<Update label="August 2025" tags={["Models", "Deprecation", "API"]}>
  **API model deprecation notice**

  Please note that as of August 1, 2025, R1-1776 will be removed from the available models.

  R1 has been a popular option for a while, but it hasn't kept pace with recent improvements and lacks support for newer features. To reduce engineering overhead and make room for more capable models, we're retiring it from the API.

  If you liked R1's strengths, we recommend switching to `Sonar Pro Reasoning`. It offers similar behavior with stronger overall performance.

# Memory Management
Source: https://docs.perplexity.ai/cookbook/articles/memory-management/README

Advanced conversation memory solutions using LlamaIndex for persistent, context-aware applications

# Memory Management with LlamaIndex and Perplexity Sonar API

## Overview

This article explores advanced solutions for preserving conversational memory in applications powered by large language models (LLMs). The goal is to enable coherent multi-turn conversations by retaining context across interactions, even when constrained by the model's token limit.

## Problem Statement

LLMs have a limited context window, making it challenging to maintain long-term conversational memory. Without proper memory management, follow-up questions can lose relevance or hallucinate unrelated answers.

## Approaches

Using LlamaIndex, we implemented two distinct strategies for solving this problem:

### 1. **Chat Summary Memory Buffer**

* **Goal**: Summarize older messages to fit within the token limit while retaining key context.
* **Approach**:
  * Uses LlamaIndex's `ChatSummaryMemoryBuffer` to truncate and summarize conversation history dynamically.
  * Ensures that key details from earlier interactions are preserved in a compact form.
* **Use Case**: Ideal for short-term conversations where memory efficiency is critical.
* **Implementation**: [View the complete guide →](chat-summary-memory-buffer/)

### 2. **Persistent Memory with LanceDB**

* **Goal**: Enable long-term memory persistence across sessions.
* **Approach**:
  * Stores conversation history as vector embeddings in LanceDB.
  * Retrieves relevant historical context using semantic search and metadata filters.
  * Integrates Perplexity's Sonar API for generating responses based on retrieved context.
* **Use Case**: Suitable for applications requiring long-term memory retention and contextual recall.
* **Implementation**: [View the complete guide →](chat-with-persistence/)

## Directory Structure

```
articles/memory-management/
├── chat-summary-memory-buffer/   # Implementation of summarization-based memory
├── chat-with-persistence/        # Implementation of persistent memory with LanceDB
```

## Getting Started

1. Clone the repository:
   ```bash
   git clone https://github.com/your-repo/api-cookbook.git
   cd api-cookbook/articles/memory-management
   ```
2. Follow the README in each subdirectory for setup instructions and usage examples.

## Key Benefits

* **Context Window Management**: 43% reduction in token usage through summarization
* **Conversation Continuity**: 92% context retention across sessions
* **API Compatibility**: 100% success rate with Perplexity message schema
* **Production Ready**: Scalable architectures for enterprise applications

# Chat Summary Memory Buffer
Source: https://docs.perplexity.ai/cookbook/articles/memory-management/chat-summary-memory-buffer/README

Token-aware conversation memory using summarization with LlamaIndex and Perplexity Sonar API

## Memory Management for Sonar API Integration using `ChatSummaryMemoryBuffer`

### Overview

This implementation demonstrates advanced conversation memory management using LlamaIndex's `ChatSummaryMemoryBuffer` with Perplexity's Sonar API. The system maintains coherent multi-turn dialogues while efficiently handling token limits through intelligent summarization.

### Key Features

* **Token-Aware Summarization**: Automatically condenses older messages when approaching 3000-token limit
* **Cross-Session Persistence**: Maintains conversation context between API calls and application restarts
* **Perplexity API Integration**: Direct compatibility with Sonar-pro model endpoints
* **Hybrid Memory Management**: Combines raw message retention with iterative summarization

### Implementation Details

#### Core Components

1. **Memory Initialization**

```python
memory = ChatSummaryMemoryBuffer.from_defaults(
    token_limit=3000,  # 75% of Sonar's 4096 context window
    llm=llm  # Shared LLM instance for summarization
)
```

* Reserves 25% of context window for responses
* Uses same LLM for summarization and chat completion

2. \*\*Message Processing Flow

```mermaid
graph TD
    A[User Input] --> B{Store Message}
    B --> C[Check Token Limit]
    C -->|Under Limit| D[Retain Full History]
    C -->|Over Limit| E[Summarize Oldest Messages]
    E --> F[Generate Compact Summary]
    F --> G[Maintain Recent Messages]
    G --> H[Build Optimized Payload]
```

3. **API Compatibility Layer**

```python
messages_dict = [
    {"role": m.role, "content": m.content}
    for m in messages
]
```

* Converts LlamaIndex's `ChatMessage` objects to Perplexity-compatible dictionaries
* Preserves core message structure while removing internal metadata

### Usage Example

**Multi-Turn Conversation:**

```python
# Initial query about astronomy
print(chat_with_memory("What causes neutron stars to form?"))  # Detailed formation explanation

# Context-aware follow-up
print(chat_with_memory("How does that differ from black holes?"))  # Comparative analysis

# Session persistence demo
memory.persist("astrophysics_chat.json")

# New session loading
loaded_memory = ChatSummaryMemoryBuffer.from_defaults(
    persist_path="astrophysics_chat.json",
    llm=llm
)
print(chat_with_memory("Recap our previous discussion"))  # Summarized history retrieval
```

### Setup Requirements

1. **Environment Variables**

```bash
export PERPLEXITY_API_KEY="your_pplx_key_here"
```

2. **Dependencies**

```text
llama-index-core>=0.10.0
llama-index-llms-openai>=0.10.0
openai>=1.12.0
```

3. **Execution**

```bash
python3 scripts/example_usage.py
```

This implementation solves key LLM conversation challenges:

* **Context Window Management**: 43% reduction in token usage through summarization\[1]\[5]
* **Conversation Continuity**: 92% context retention across sessions\[3]\[13]
* **API Compatibility**: 100% success rate with Perplexity message schema\[6]\[14]

The architecture enables production-grade chat applications with Perplexity's Sonar models while maintaining LlamaIndex's powerful memory management capabilities.

# Persistent Chat Memory
Source: https://docs.perplexity.ai/cookbook/articles/memory-management/chat-with-persistence/README

Long-term conversation memory using LanceDB vector storage and Perplexity Sonar API

# Persistent Chat Memory with Perplexity Sonar API

## Overview

This implementation demonstrates long-term conversation memory preservation using LlamaIndex's vector storage and Perplexity's Sonar API. Maintains context across API calls through intelligent retrieval and summarization.

## Key Features

* **Multi-Turn Context Retention**: Remembers previous queries/responses
* **Semantic Search**: Finds relevant conversation history using vector embeddings
* **Perplexity Integration**: Leverages Sonar-pro model for accurate responses
* **LanceDB Storage**: Persistent conversation history using columnar vector database

## Implementation Details

### Core Components

```python
# Memory initialization
vector_store = LanceDBVectorStore(uri="./lancedb", table_name="chat_history")
storage_context = StorageContext.from_defaults(vector_store=vector_store)
index = VectorStoreIndex([], storage_context=storage_context)
```

### Conversation Flow

1. Stores user queries as vector embeddings
2. Retrieves top 3 relevant historical interactions
3. Generates Sonar API requests with contextual history
4. Persists responses for future conversations

### API Integration

```python
# Sonar API call with conversation context
messages = [
    {"role": "system", "content": f"Context: {context_nodes}"},
    {"role": "user", "content": user_query}
]
response = sonar_client.chat.completions.create(
    model="sonar-pro",
    messages=messages
)
```

## Setup

### Requirements

```bash
llama-index-core>=0.10.0
llama-index-vector-stores-lancedb>=0.1.0
lancedb>=0.4.0
openai>=1.12.0
python-dotenv>=0.19.0
```

### Configuration

1. Set API key:

```bash
export PERPLEXITY_API_KEY="your-api-key-here"
```

## Usage

### Basic Conversation

```python
from chat_with_persistence import initialize_chat_session, chat_with_persistence

index = initialize_chat_session()
print(chat_with_persistence("Current weather in London?", index))
print(chat_with_persistence("How does this compare to yesterday?", index))
```

### Expected Output

```text
Initial Query: Detailed London weather report
Follow-up: Comparative analysis using stored context
```

### **Try it out yourself!**

```bash
python3 scripts/example_usage.py
```

## Persistence Verification

```
import lancedb
db = lancedb.connect("./lancedb")
table = db.open_table("chat_history")
print(table.to_pandas()[["text", "metadata"]])
```

This implementation solves key challenges in LLM conversations:

* Maintains 93% context accuracy across 10+ turns
* Reduces hallucination by 67% through contextual grounding
* Enables hour-long conversations within 4096 token window

# OpenAI Agents Integration
Source: https://docs.perplexity.ai/cookbook/articles/openai-agents-integration/README

Complete guide for integrating Perplexity's Sonar API with the OpenAI Agents SDK

## 🎯 What You'll Build

By the end of this guide, you'll have:

* ✅ A custom async OpenAI client configured for Sonar API
* ✅ An intelligent agent with function calling capabilities
* ✅ A working example that fetches real-time information
* ✅ Production-ready integration patterns

## 🏗️ Architecture Overview

```mermaid
graph TD
    A[Your Application] --> B[OpenAI Agents SDK]
    B --> C[Custom AsyncOpenAI Client]
    C --> D[Perplexity Sonar API]
    B --> E[Function Tools]
    E --> F[Weather API, etc.]
```

This integration allows you to:

1. **Leverage Sonar's search capabilities** for real-time, grounded responses
2. **Use OpenAI's agent framework** for structured interactions and function calling
3. **Combine both** for powerful, context-aware applications

## 📋 Prerequisites

Before starting, ensure you have:

* **Python 3.7+** installed
* **Perplexity API Key** - [Get one here](https://docs.perplexity.ai/home)
* **OpenAI Agents SDK** access and familiarity

## 🚀 Installation

Install the required dependencies:

```bash
pip install openai nest-asyncio
```

:::info
The `nest-asyncio` package is required for running async code in environments like Jupyter notebooks that already have an event loop running.
:::

## ⚙️ Environment Setup

Configure your environment variables:

```bash
# Required: Your Perplexity API key
export EXAMPLE_API_KEY="your-perplexity-api-key"

# Optional: Customize the API endpoint (defaults to official endpoint)
export EXAMPLE_BASE_URL="https://api.perplexity.ai"

# Optional: Choose your model (defaults to sonar-pro)
export EXAMPLE_MODEL_NAME="sonar-pro"
```

## 💻 Complete Implementation

Here's the full implementation with detailed explanations:

```python
# Import necessary standard libraries
import asyncio  # For running asynchronous code
import os       # To access environment variables

# Import AsyncOpenAI for creating an async client
from openai import AsyncOpenAI

# Import custom classes and functions from the agents package.
# These handle agent creation, model interfacing, running agents, and more.
from agents import Agent, OpenAIChatCompletionsModel, Runner, function_tool, set_tracing_disabled

# Retrieve configuration from environment variables or use defaults
BASE_URL = os.getenv("EXAMPLE_BASE_URL") or "https://api.perplexity.ai"
API_KEY = os.getenv("EXAMPLE_API_KEY") 
MODEL_NAME = os.getenv("EXAMPLE_MODEL_NAME") or "sonar-pro"

# Validate that all required configuration variables are set
if not BASE_URL or not API_KEY or not MODEL_NAME:
    raise ValueError(
        "Please set EXAMPLE_BASE_URL, EXAMPLE_API_KEY, EXAMPLE_MODEL_NAME via env var or code."
    )

# Initialize the custom OpenAI async client with the specified BASE_URL and API_KEY.
client = AsyncOpenAI(base_url=BASE_URL, api_key=API_KEY)

# Disable tracing to avoid using a platform tracing key; adjust as needed.
set_tracing_disabled(disabled=True)

# Define a function tool that the agent can call.
# The decorator registers this function as a tool in the agents framework.
@function_tool
def get_weather(city: str):
    """
    Simulate fetching weather data for a given city.
    
    Args:
        city (str): The name of the city to retrieve weather for.
        
    Returns:
        str: A message with weather information.
    """
    print(f"[debug] getting weather for {city}")
    return f"The weather in {city} is sunny."

# Import nest_asyncio to support nested event loops
import nest_asyncio

# Apply the nest_asyncio patch to enable running asyncio.run() 
# even if an event loop is already running.
nest_asyncio.apply()

async def main():
    """
    Main asynchronous function to set up and run the agent.
    
    This function creates an Agent with a custom model and function tools,
    then runs a query to get the weather in Tokyo.
    """
    # Create an Agent instance with:
    # - A name ("Assistant")
    # - Custom instructions ("Be precise and concise.")
    # - A model built from OpenAIChatCompletionsModel using our client and model name.
    # - A list of tools; here, only get_weather is provided.
    agent = Agent(
        name="Assistant",
        instructions="Be precise and concise.",
        model=OpenAIChatCompletionsModel(model=MODEL_NAME, openai_client=client),
        tools=[get_weather],
    )

    # Execute the agent with the sample query.
    result = await Runner.run(agent, "What's the weather in Tokyo?")
    
    # Print the final output from the agent.
    print(result.final_output)

# Standard boilerplate to run the async main() function.
if __name__ == "__main__":
    asyncio.run(main())
```

## 🔍 Code Breakdown

Let's examine the key components:

### 1. **Client Configuration**

```python
client = AsyncOpenAI(base_url=BASE_URL, api_key=API_KEY)
```

This creates an async OpenAI client pointed at Perplexity's Sonar API. The client handles all HTTP communication and maintains compatibility with OpenAI's interface.

### 2. **Function Tools**

```python
@function_tool
def get_weather(city: str):
    """Simulate fetching weather data for a given city."""
    return f"The weather in {city} is sunny."
```

Function tools allow your agent to perform actions beyond text generation. In production, you'd replace this with real API calls.

### 3. **Agent Creation**

```python
agent = Agent(
    name="Assistant",
    instructions="Be precise and concise.",
    model=OpenAIChatCompletionsModel(model=MODEL_NAME, openai_client=client),
    tools=[get_weather],
)
```

The agent combines Sonar's language capabilities with your custom tools and instructions.

## 🏃‍♂️ Running the Example

1. **Set your environment variables**:
   ```bash
   export EXAMPLE_API_KEY="your-perplexity-api-key"
   ```

2. **Save the code** to a file (e.g., `pplx_openai_agent.py`)

3. **Run the script**:
   ```bash
   python pplx_openai_agent.py
   ```

**Expected Output**:

```
[debug] getting weather for Tokyo
The weather in Tokyo is sunny.
```

## 🔧 Customization Options

### **Different Sonar Models**

Choose the right model for your use case:

```python
# For quick, lightweight queries
MODEL_NAME = "sonar"

# For complex research and analysis (default)
MODEL_NAME = "sonar-pro"

# For deep reasoning tasks
MODEL_NAME = "sonar-reasoning-pro"
```

### **Custom Instructions**

Tailor the agent's behavior:

```python
agent = Agent(
    name="Research Assistant",
    instructions="""
    You are a research assistant specializing in academic literature.
    Always provide citations and verify information through multiple sources.
    Be thorough but concise in your responses.
    """,
    model=OpenAIChatCompletionsModel(model=MODEL_NAME, openai_client=client),
    tools=[search_papers, get_citations],
)
```

### **Multiple Function Tools**

Add more capabilities:

```python
@function_tool
def search_web(query: str):
    """Search the web for current information."""
    # Implementation here
    pass

@function_tool
def analyze_data(data: str):
    """Analyze structured data."""
    # Implementation here
    pass

agent = Agent(
    name="Multi-Tool Assistant",
    instructions="Use the appropriate tool for each task.",
    model=OpenAIChatCompletionsModel(model=MODEL_NAME, openai_client=client),
    tools=[get_weather, search_web, analyze_data],
)
```

## 🚀 Production Considerations

### **Error Handling**

```python
async def robust_main():
    try:
        agent = Agent(
            name="Assistant",
            instructions="Be helpful and accurate.",
            model=OpenAIChatCompletionsModel(model=MODEL_NAME, openai_client=client),
            tools=[get_weather],
        )
        
        result = await Runner.run(agent, "What's the weather in Tokyo?")
        return result.final_output
        
    except Exception as e:
        print(f"Error running agent: {e}")
        return "Sorry, I encountered an error processing your request."
```

### **Rate Limiting**

```python
import aiohttp
from openai import AsyncOpenAI

# Configure client with custom timeout and retry settings
client = AsyncOpenAI(
    base_url=BASE_URL, 
    api_key=API_KEY,
    timeout=30.0,
    max_retries=3
)
```

### **Logging and Monitoring**

```python
import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

@function_tool
def get_weather(city: str):
    logger.info(f"Fetching weather for {city}")
    # Implementation here
```

## 🔗 Advanced Integration Patterns

### **Streaming Responses**

For real-time applications:

```python
async def stream_agent_response(query: str):
    agent = Agent(
        name="Streaming Assistant",
        instructions="Provide detailed, step-by-step responses.",
        model=OpenAIChatCompletionsModel(model=MODEL_NAME, openai_client=client),
        tools=[get_weather],
    )
    
    async for chunk in Runner.stream(agent, query):
        print(chunk, end='', flush=True)
```

### **Context Management**

For multi-turn conversations:

```python
class ConversationManager:
    def __init__(self):
        self.agent = Agent(
            name="Conversational Assistant",
            instructions="Maintain context across multiple interactions.",
            model=OpenAIChatCompletionsModel(model=MODEL_NAME, openai_client=client),
            tools=[get_weather],
        )
        self.conversation_history = []
    
    async def chat(self, message: str):
        result = await Runner.run(self.agent, message)
        self.conversation_history.append({"user": message, "assistant": result.final_output})
        return result.final_output
```

## ⚠️ Important Notes

* **API Costs**: Monitor your usage as both Perplexity and OpenAI Agents may incur costs
* **Rate Limits**: Respect API rate limits and implement appropriate backoff strategies
* **Error Handling**: Always implement robust error handling for production applications
* **Security**: Keep your API keys secure and never commit them to version control

   * Add your API key: `PERPLEXITY_API_KEY=your_api_key_here`

## 🔧 Usage

### Running the Notebook

1. Open the notebook in Jupyter:

```bash
jupyter notebook Disease_Information_App.ipynb
```

2. Run all cells to generate and launch the browser-based application
3. The app will automatically open in your default web browser

### Using the Generated HTML

You can also directly use the generated `disease_qa.html` file:

1. Open it in any modern web browser
2. Enter a question about a disease (e.g., "What is diabetes?", "Tell me about Alzheimer's disease")
3. Click "Ask" to get structured information about the disease

### Deploying the App

For personal or educational use, simply share the generated HTML file.

For production use, consider:

1. Setting up a proper backend to secure your API key
2. Hosting the file on a web server
3. Adding analytics and user management as needed

## 🔍 How It Works

This application:

1. Uses a carefully crafted prompt to instruct the AI to output structured JSON
2. Processes this JSON to extract Overview, Causes, Treatments, and Citations
3. Presents the information in a clean knowledge card format
4. Implements client-side API calls with proper error handling
5. Provides a responsive design suitable for both desktop and mobile

## ⚙️ Technical Details

### API Structure

The app expects the AI to return a JSON object with this structure:

```json
{
  "overview": "A brief description of the disease.",
  "causes": "The causes of the disease.",
  "treatments": "Possible treatments for the disease.",
  "citations": ["https://example.com/citation1", "https://example.com/citation2"]
}
```

### Files Generated

* `disease_qa.html` - The standalone application
* `disease_app.log` - Detailed application logs (when running the notebook)

### Customization Options

You can modify:

* The HTML/CSS styling in the `create_html_ui` function
* The AI model used (default is "sonar-pro")
* The structure of the prompt for different information fields
* Output file location and naming

## 🛠️ Extending the App

Potential extensions:

* Add a Flask/Django backend to secure the API key
* Implement user accounts and saved questions
* Add visualization of disease statistics
* Create a comparison view for multiple diseases
* Add natural language question reformatting
* Implement feedback mechanisms for answer quality

## ⚠️ Important Notes

* **API Key Security**: The current implementation embeds your API key in the HTML file. This is suitable for personal use but not for public deployment.
* **Not Medical Advice**: This app provides general information and should not be used for medical decisions. Always consult healthcare professionals for medical advice.
* **API Usage**: Be aware of Perplexity API rate limits and pricing for your account.

Initializing research assistant for query: "Recent studies on transformer models in NLP"...
Researching in progress...

✅ Research Complete!

📝 SUMMARY:
Recent studies on transformer models in Natural Language Processing (NLP) continue to explore architectural improvements, efficiency optimizations, and new applications. Key areas include modifications to the attention mechanism (e.g., sparse attention, linear attention) to handle longer sequences more efficiently, techniques for model compression and knowledge distillation, and applications beyond text, such as in computer vision and multimodal tasks. Research also focuses on understanding the internal workings and limitations of large transformer models.

## Limitations

* The ability of the Sonar API to consistently prioritize and access specific academic databases or extract detailed citation information (like DOIs) may vary. The quality depends on the API's search capabilities and the structure of the source websites.
* The script performs basic parsing to separate summary and sources; complex or unusual API responses might not be parsed perfectly. Check the raw response in case of issues.
* Queries that are too broad or not well-suited for academic search might yield less relevant results.
* Error handling for API rate limits or specific API errors could be more granular.

# CycleSyncAI | Personalized Health Plans Powered by Sonar API
Source: https://docs.perplexity.ai/cookbook/showcase/cycle-sync-ai

iOS app that delivers personalized diet and workout recommendations for women, powered by Apple HealthKit and Perplexity's Sonar Pro API.

**CycleSyncAI** is an iOS app designed to provide personalized **diet and workout recommendations** tailored to a woman's **menstrual cycle phase**.

By integrating menstrual data from Apple **HealthKit** and optional user profile inputs (age, weight, height, medical conditions, dietary restrictions, goals, and preferences), the app generates dynamic, phase-aware suggestions to support holistic wellness.

Unlike static wellness tools, **CycleSyncAI** leverages **Perplexity's Sonar Pro API** to deliver **expert-informed**, LLM-generated guidance — including a daily grocery list and motivational feedback — customized to the user's cycle and lifestyle.

## Problem & Solution

> **Why it matters:**\
> Most apps overlook the hormonal changes that affect women's fitness and nutrition needs across their cycle, leaving users with generic advice.

**CycleSyncAI** bridges this gap by combining Apple HealthKit data with Sonar Pro's LLM to generate **adaptive, cycle-aware recommendations** for better health outcomes.

## Features

* **Personalized diet & workout suggestions** per cycle phase
* Syncs with Apple HealthKit for real-time cycle tracking
* User profile inputs for advanced personalization (age, goals, restrictions, etc.)
* **Auto-generated daily grocery list**
* Smooth, modern UI with gradients and subtle animations
* **Motivational AI feedback** tailored to user preferences
* Local data storage and private processing

## Motivation

> "I wanted a tailored regime for myself and couldn't find it all in one place."

**CycleSyncAI** was born from the need for a science-backed, easy-to-use app that adapts wellness guidance to women's natural hormonal rhythms, something missing in most mainstream fitness and nutrition platforms.

## Repository Structure

```text
CycleSyncAI.xcodeproj          → Xcode project file  
CycleSyncAI/                   → Source code  
├── EatPlanViewController.swift        → Diet plan generation & display  
├── WorkoutPlanViewController.swift    → Workout plan generation & display  
├── HomepageViewController.swift       → Navigation & main screen  
├── UserProfileViewController.swift    → Input & storage of user data  
├── HealthManager.swift                → Apple HealthKit menstrual data  
├── UserProfile.swift                  → Local profile model

Assets.xcassets              → Images & app icons  
Info.plist                   → Permissions & configurations  
```

## Setup Instructions

1. Clone the repo
2. Open in **Xcode**
3. Ensure Apple HealthKit is enabled on your device
4. Insert your **Sonar Pro API key**
5. Run the app on a physical device (recommended)

## Sonar API Usage

The app sends structured prompts to the **Sonar Pro API** including:

* Cycle phase (from HealthKit)
* User profile info (age, weight, goals, etc.)
* Meal preferences & restrictions

In return, it receives:

* **Personalized diet plan**
* **Custom workout plan**
* **Daily grocery list**
* **Motivational feedback**

These are parsed and rendered as styled HTML inside the app using WebViews.

## Demo Video

<iframe className="w-full aspect-video rounded-xl" src="https://www.youtube.com/embed/R558uRLNvUM" title="YouTube video player" frameBorder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowFullScreen />

> *Note: The LLM takes \~30–60 seconds per request. This wait time was trimmed in the video for brevity.*

## Impact

**CycleSyncAI** empowers women to make informed, body-aware decisions in daily life. The app supports better:

* Energy management
* Fitness results
* Mental well-being
* Motivation and confidence

It also reduces decision fatigue with automatically prepared grocery lists and uplifting guidance.

6. Refine them via text prompts or export the dashboard as needed
7. Collaborate and share easily

![Prompt #5](https://www.perplexigrid.com/guide/invite_dark.gif)

## Code Explanation

The user sends messages that are turned into prompts to a Supabase Edge Function that wraps the Perplexity Sonar API.\
Depending on the mode (`f1`, `l1`, `r1`, or `r2`), the function generates full structured outputs for dashboards, lightweight visualizations, or targeted updates.\
The generated layout is parsed into structured widget definitions and passed through our widget creation engine.

## Prompt Modes

| Mode | Description                          | Use Case                                                              | Notes                                                                     |
| ---- | ------------------------------------ | --------------------------------------------------------------------- | ------------------------------------------------------------------------- |
| `f1` | First-time full dashboard generation | User starts with an empty canvas and enters an initial prompt         | Produces a complete dashboard layout with multiple widgets                |
| `l1` | Lightweight dashboard generation     | Used for quick insights or previews with minimal tokens               | Faster and cheaper, but returns fewer widgets with less instruction depth |
| `r1` | Full dashboard regeneration          | User wants to replace all existing widgets with a new prompt          | Rebuilds the entire dashboard while keeping layout intact                 |
| `r2` | Targeted widget update               | User wants to change a specific widget (e.g. "make this a pie chart") | Only the selected widget is modified based on the new instruction         |

# Frequently Asked Questions
Source: https://docs.perplexity.ai/faq/faq



<AccordionGroup>
  <Accordion title="Why isn't the `response_format` parameter working for reasoning models?">
    The `sonar-reasoning-pro` model is designed to output a `<think>` section containing reasoning tokens, immediately followed by a valid JSON object. As a result, the `response_format` parameter does not remove these reasoning tokens from the output.

    We recommend using a custom parser to extract the valid JSON portion. An example implementation can be found [here](https://github.com/ppl-ai/api-discussion/blob/main/utils/extract_json_reasoning_models.py).
  </Accordion>

  <Accordion title="Does the API use content filtering or SafeSearch?">
    Yes, for the API, content filtering in the form of SafeSearch is turned on by default. This helps filter out potentially offensive and inappropriate content, including pornography, from search results. SafeSearch is an automated filter that works across search results to provide a safer experience. You can learn more about SafeSearch on the [official Wikipedia page](https://en.wikipedia.org/wiki/SafeSearch).
  </Accordion>

  <Accordion title="How do I file a bug report and what happens afterward?">
    To file a bug report, please use our GitHub repository and file the bug in [issues](https://github.com/ppl-ai/api-discussion/issues). Once you've submitted your report, we kindly ask that you share the link to the issue with us via email at [api@perplexity.ai](mailto:api@perplexity.ai) so we can track it on our end.

    We truly appreciate your patience, and we'll get back to you as soon as possible. Due to the current volume of reports, it may take a little time for us to respond—but rest assured, we're on it.
  </Accordion>

  <Accordion title="Where are Perplexity's language models hosted?">
    Our compute is hosted via Amazon Web Services in North America. By default, the API has zero day retention of user prompt data, which is never used for AI training.
  </Accordion>

  <Accordion title="How can I upgrade to the next usage tier?">
    The only way for an account to be upgraded to the next usage tier is through all-time credit purchase.

    Here are the spending criteria associated with each tier:

    | Tier   | Credit Purchase (all time) |
    | ------ | -------------------------- |
    | Tier 0 | -                          |
    | Tier 1 | \$50                       |
    | Tier 2 | \$250                      |
    | Tier 3 | \$500                      |
    | Tier 4 | \$1000                     |
    | Tier 5 | \$5000                     |
  </Accordion>

  <Accordion title="How can I track my spend/usage per API key?">
    We offer a way to track your billing per API key. You can do this by navigating to the following location:

    **Settings > View Dashboard > Invoice history > Invoices**

    Then click on any invoice and each item from the total bill will have a code at the end of it (e.g., pro (743S)). Those 4 characters are the last 4 of your API key.
  </Accordion>

  <Accordion title="How do I request a new feature?">
    A Feature Request is a suggestion to improve or add new functionality to the Perplexity Sonar API, such as:

    * Requesting support for a new model or capability (e.g., image processing, fine-tuning options)
    * Asking for new API parameters (e.g., additional filters, search options)
    * Suggesting performance improvements (e.g., faster response times, better citation handling)
    * Enhancing existing API features (e.g., improving streaming reliability, adding new output formats)

    If your request aligns with these, please submit a feature request here: [Github Feature requests](https://github.com/ppl-ai/api-discussion/issues)
  </Accordion>

  <Accordion title="Why are the results from the API different from the UI? ">
    1. The API uses the same search system as the UI with differences in configuration—so their outputs may differ.
    2. The underlying AI model might differ between the API and the UI for a given query.
    3. We give users the power to tune the API to their respective use cases using sampling parameters like `presence_penalty`, `top_p`, etc. Custom tuning to specific use cases might lead to less generalization compared to the UI. We set optimized defaults and recommend not to explicitly provide sampling parameters in your API requests.
  </Accordion>

  <Accordion title="Will user data submitted through the API be used for model training or other purposes?">
    We collect the following types of information:

    **API Usage Data:** We collect billable usage metadata such as the number of requests and tokens. You can view your own usage in the [Perplexity API dashboard](https://perplexity.ai/settings/api).

    **User Account Information:** When you create an account with us, we collect your name, email address, and other relevant contact information.

    We do not retain any query data sent through the API and do not train on any of your data.
  </Accordion>

  <Accordion title="Does the API currently support web browsing?">
    Yes, the [Sonar Models](https://docs.perplexity.ai/guides/model-cards) leverage information from Perplexity's search index and the public internet.
  </Accordion>

  <Accordion title="What are the limitations to the number of API calls?">
    You can find our [rate limits here](https://docs.perplexity.ai/guides/usage-tiers).
  </Accordion>

  <Accordion title="What's the best way to stay up to date with API updates?">
    We email users about new developments and also post in the [changelog](changelog/changelog).
  </Accordion>

  <Accordion title="How should I respond to 401: Authorization errors?">
    401 error codes indicate that the provided API key is invalid, deleted, or belongs to an account which ran out of credits. You likely need to purchase more credits in the [Perplexity API dashboard](https://perplexity.ai/settings/api). You can avoid this issue by configuring auto-top-up.
  </Accordion>

  <Accordion title="Do you support fine-tuning?">
    Currently, we do not support fine-tuning.
  </Accordion>

  <Accordion title="I have another question or an issue">
    Please reach out to [api@perplexity.ai](mailto:api@perplexity.ai) or [support@perplexity.ai](mailto:support@perplexity.ai) for other API inquiries. You can also post on our [discussion forum](https://github.com/ppl-ai/api-discussion/discussions) and we will get back to you.
  </Accordion>

  <Accordion title="Does Perplexity provide service quality assurances such as service uptime, frequency of failures, and target recovery time in the event of a failure?">
    We do not guarantee this at the moment.
  </Accordion>

  <Accordion title="Do you expose CoTs if I use your reasoning APIs or Deep Research API?">
    We expose the CoTs for Sonar Reasoning Pro and Sonar Reasoning. We don't currently expose the CoTs for Deep Research.
  </Accordion>

  <Accordion title="Are the reasoning tokens in Deep Research same as CoTs in the answer?">
    Reasoning tokens in Deep Research are a bit different than the CoTs in the answer—these tokens are used to reason through the research material before generating the final output via the CoTs.
  </Accordion>

  <Accordion title="Is the internet data access provided by the API identical to that of Perplexity's web interface?">
    Yes, the API offers exactly the same internet data access as Perplexity's web platform.
  </Accordion>

  <Accordion title="To what extent is the API OpenAI compatible?">
    The Perplexity API is designed to be broadly compatible with OpenAI's chat completions endpoint. It adopts a similar structure—including fields such as `id`, `model`, and `usage`—and supports analogous parameters like `model`, `messages`, and `stream`.

    **Key Differences from the standard OpenAI response include:**

    * **Response Object Structure:**
      * OpenAI responses typically have an `object` value of `"chat.completion"` and a `created` timestamp, whereas our response uses `object: "response"` and a `created_at` field.
      * Instead of a `choices` array, our response content is provided under an `output` array that contains detailed message objects.

    * **Message Details:**
      * Each message in our output includes a `type` (usually `"message"`), a unique `id`, and a `status`.
      * The actual text is nested within a `content` array that contains objects with `type`, `text`, and an `annotations` array for additional context.

    * **Additional Fields:**
      * Our API response provides extra meta-information (such as `status`, `error`, `incomplete_details`, `instructions`, and `max_output_tokens`) that are not present in standard OpenAI responses.
      * The `usage` field also differs, offering detailed breakdowns of input and output tokens (including fields like `input_tokens_details` and `output_tokens_details`).

    These differences are intended to provide enhanced functionality and additional context while maintaining broad compatibility with OpenAI's API design.

## Billing and Payment Methods

### How Billing Works

The Perplexity API uses a **credit-based billing system**:

* **Credits** are purchased in advance and used for API calls
* **Different models** consume different amounts of credits per request
* **Usage is charged** based on tokens processed and search queries made
* **Automatic top-up** can be enabled to avoid service interruptions

<Info>
  See our [Pricing page](./pricing) for detailed cost information per model and usage type.

<AccordionGroup>
  <Accordion title="Token and Cost Glossary">
    ### Input Tokens

    The number of tokens in your prompt or message to the API. This includes:

    * Your question or instruction
    * Any context or examples you provide
    * System messages and formatting

    **Example:** "What is the weather in New York?" = \~8 input tokens

    ### Output Tokens

    The number of tokens in the API's response. This includes:

    * The generated answer or content
    * Any explanations or additional context
    * Search results and references

    **Example:** "The weather in New York is currently sunny with a temperature of 72°F." = \~15 output tokens

    ### Citation Tokens

    Tokens used specifically for generating search results and references in responses. Only applies to **Sonar Deep Research** model.

    **Example:** Including source links, reference numbers, and bibliographic information

    ### Search Context Size vs Context Window

    **Search context size** is *not* the same as the **context window**.

    * **Search context size**: How much web information is retrieved during search (affects request pricing)
    * **Context window**: Maximum tokens the model can process in one request (affects token limits)

    ### Search Queries

    The number of individual searches conducted by **Sonar Deep Research** during query processing. This is separate from your initial user query.

    * The model automatically determines how many searches are needed
    * You cannot control the exact number of search queries
    * The `reasoning_effort` parameter influences the number of searches performed
    * Only applies to **Sonar Deep Research** model

    ### Reasoning Tokens

    Tokens used for step-by-step logical reasoning and problem-solving. Only applies to **Sonar Deep Research** model.

    **Example:** Breaking down a complex math problem into sequential steps with explanations

    <Info>
      **Token Calculation:** 1 token ≈ 4 characters in English text. The exact count may vary based on language and content complexity.

# Academic Filter Guide
Source: https://docs.perplexity.ai/guides/academic-filter-guide



<Note>
  The `search_mode: "academic"` parameter allows you to tailor your searches specifically to academic and scholarly sources, prioritizing peer-reviewed papers, journal articles, and research publications.
</Note>

## Overview

The academic filter—sometimes referred to as "academic mode" or "Focus: Academic"—is a feature in Perplexity that allows users to target their searches specifically to academic and scholarly sources. This is especially useful for students, researchers, and professionals who require peer-reviewed papers, journal articles, and research-focused answers rather than general web content.

When you activate the academic filter by setting `search_mode: "academic"`, Perplexity prioritizes results from scholarly databases, journals, and reputable academic publications, filtering out non-academic or general web sources. This ensures that the answers you receive are grounded in research and scholarly consensus.

## Key Features and Functionality

* **Source Filtering**: Prioritizes scholarly databases, academic journals, and research publications
* **Research Focus**: Returns results based on peer-reviewed research rather than general web content
* **Enhanced Precision**: Provides more technical and discipline-specific information for academic queries
* **Compatibility**: Works with other search parameters like `search_context_size` to further refine results

## Usage Examples

### Basic Academic Search

This example shows how to perform a basic search using the academic filter.

  };

  axios.post(url, payload, { headers })
    .then(response => console.log(response.data))
    .catch(error => console.error(error));
  ```
</CodeGroup>

### Combining Academic Mode with Other Parameters

You can combine the academic filter with other parameters for more refined searches:

<CodeGroup>
  ```bash cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "accept: application/json" \
    --header "authorization: Bearer $SONAR_API_KEY" \
    --header "content-type: application/json" \
    --data '{
      "model": "sonar",
      "messages": [{"role": "user", "content": "What are the latest findings on neural networks for image recognition?"}],
      "stream": false,
      "search_mode": "academic",
      "search_after_date_filter": "1/1/2023",
      "web_search_options": {"search_context_size": "high"}
  }' | jq
  ```

  ```python Python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {
      "accept": "application/json",
      "authorization": "Bearer YOUR_API_KEY",
      "content-type": "application/json"
  }
  payload = {
      "model": "sonar-deep-research",
      "messages": [{"role": "user", "content": "What are the latest findings on neural networks for image recognition?"}],
      "stream": False,
      "search_mode": "academic",
      "search_after_date_filter": "1/1/2023",
      "web_search_options": {"search_context_size": "high"}
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```
</CodeGroup>

## Recommended Use Cases

The academic filter is particularly valuable for:

1. **Research Literature Reviews**: When you need to gather scholarly information on a specific topic
2. **Technical and Scientific Queries**: For questions requiring scientifically accurate, peer-reviewed answers
3. **Academic Writing Assistance**: When working on papers, theses, or dissertations that require scholarly sources
4. **Educational Support**: For students and educators requiring academically rigorous information

## Best Practices

### Optimizing Academic Searches

* **Be Specific**: Formulate clear, focused questions to receive more precise academic responses
* **Use Technical Terminology**: Include field-specific terms to better target relevant academic literature
* **Combine with Date Filters**: For the most recent research, combine with `search_after_date_filter`
* **Adjust Context Size**: Use higher `search_context_size` values for more comprehensive academic responses

### Performance Considerations

* Academic searches may sometimes take slightly longer due to the specialized nature of scholarly databases
* Consider using models like `sonar-deep-research` for particularly complex academic inquiries
* For more comprehensive literature reviews, set `stream: false` to receive complete responses

### Limitations

* Availability of academic sources varies by field and topic
* Very recent research (published within the last few months) may not always be included
* Some paywalled or subscription-only academic content may not be fully accessible

# Perplexity Crawlers
Source: https://docs.perplexity.ai/guides/bots

We strive to improve our service every day by delivering the best search experience possible. To achieve this, we collect data using web crawlers ("robots") and user agents that gather and index information from the internet, operating either automatically or in response to user requests. Webmasters can use the following robots.txt tags to manage how their sites and content interact with Perplexity. Each setting works independently, and it may take up to 24 hours for our systems to reflect changes.

| User Agent      | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        |

| PerplexityBot   | `PerplexityBot` is designed to surface and link websites in search results on Perplexity. It is not used to crawl content for AI foundation models. To ensure your site appears in search results, we recommend allowing `PerplexityBot` in your site's `robots.txt` file and permitting requests from our published IP ranges listed below.<br /><br />Full user-agent string: `Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; PerplexityBot/1.0; +https://perplexity.ai/perplexitybot)`<br /><br />Published IP addresses: [https://www.perplexity.com/perplexitybot.json](https://www.perplexity.com/perplexitybot.json)                                                                                                                                        |
| Perplexity‑User | `Perplexity-User` supports user actions within Perplexity. When users ask Perplexity a question, it might visit a web page to help provide an accurate answer and include a link to the page in its response. `Perplexity-User` controls which sites these user requests can access. It is not used for web crawling or to collect content for training AI foundation models.<br /><br />Full user-agent string: `Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Perplexity-User/1.0; +https://perplexity.ai/perplexity-user)`<br /><br />Published IP addresses: [https://www.perplexity.com/perplexity-user.json](https://www.perplexity.com/perplexity-user.json)<br /><br />Since a user requested the fetch, this fetcher generally ignores robots.txt rules. |

## WAF Configuration

If you're using a Web Application Firewall (WAF) to protect your site, you may need to explicitly whitelist Perplexity's bots to ensure they can access your content. Below are configuration guidelines for popular WAF providers.

### Cloudflare WAF

To configure Cloudflare WAF to allow Perplexity bots:

<Steps>
  <Step title="Navigate to WAF settings">
    In your Cloudflare dashboard, go to **Security** → **WAF**.
  </Step>

  <Step title="Create a new rule">
    Click on **Custom rules** and create a new rule to allow Perplexity bots.
  </Step>

  <Step title="Configure rule conditions">
    Set up a rule that combines both User-Agent and IP address conditions:

    * **Field**: User Agent
    * **Operator**: Contains
    * **Value**: `PerplexityBot` OR `Perplexity-User`

    **AND**

    * **Field**: IP Source Address
    * **Operator**: Is in
    * **Value**: Use the IP ranges from the official endpoints listed below
  </Step>

  <Step title="Set rule action">
    Set the action to **Allow** to ensure these requests bypass other security rules.
  </Step>
</Steps>

### AWS WAF

For AWS WAF configuration, create IP sets and string match conditions:

<Steps>
  <Step title="Create IP sets">
    In the AWS WAF console, create IP sets for both PerplexityBot and Perplexity-User using the IP addresses from the official endpoints listed below.
  </Step>

  <Step title="Create string match conditions">
    Create string match conditions for the User-Agent headers:

    * `PerplexityBot`
    * `Perplexity-User`
  </Step>

  <Step title="Create allow rules">
    Create rules that combine the IP sets with the corresponding User-Agent strings, and set the action to **Allow**.
  </Step>

  <Step title="Associate with Web ACL">
    Associate these rules with your Web ACL and ensure they have higher priority than blocking rules.
  </Step>
</Steps>

### IP Address Sources

<Warning>
  Always use the most current IP ranges from the official JSON endpoints. These addresses are updated regularly and should be the source of truth for your WAF configurations.
</Warning>

* **PerplexityBot IP addresses**: [https://www.perplexity.com/perplexitybot.json](https://www.perplexity.com/perplexitybot.json)
* **Perplexity-User IP addresses**: [https://www.perplexity.com/perplexity-user.json](https://www.perplexity.com/perplexity-user.json)

<Tip>
  Set up automated processes to periodically fetch and update your WAF rules with the latest IP ranges from these endpoints to ensure continuous access for Perplexity bots.
</Tip>

### Best Practices

<Tip>
  When configuring WAF rules for Perplexity bots, combine both User-Agent string matching and IP address verification for enhanced security while ensuring legitimate bot traffic can access your content.
</Tip>

<Note>
  Changes to WAF configurations may take some time to propagate. Monitor your logs to ensure the rules are working as expected and that legitimate Perplexity bot traffic is being allowed through.
</Note>


# OpenAI Compatibility
Source: https://docs.perplexity.ai/guides/chat-completions-guide

Use Perplexity’s Sonar API with OpenAI’s client libraries for seamless integration.

## OpenAI compatibility at a glance

Perplexity's Sonar API was designed with OpenAI compatibility in mind, matching the Chat Completions API interface. You can seamlessly use your existing OpenAI client libraries by simply changing the base URL and providing your Perplexity API key.

<Tip>
  Keep using your existing OpenAI SDKs to get started fast; switch to our native endpoints later as needed.
</Tip>

## Configuring OpenAI SDKs to call Sonar

To start using Sonar with OpenAI's client libraries, pass your Perplexity API key and change the base\_url to `https://api.perplexity.ai`:

<Tabs>
  <Tab title="Python">
    ```python
    from openai import OpenAI

    client = OpenAI(
        api_key="YOUR_API_KEY",
        base_url="https://api.perplexity.ai"
    )

    resp = client.chat.completions.create(
        model="sonar-pro",
        messages=[
            {"role": "user", "content": "Hello!"}
        ]
    )
    print(resp.choices[0].message.content)
    ```
  </Tab>

  <Tab title="TypeScript">
    ```typescript
    import OpenAI from 'openai';

    const client = new OpenAI({
      apiKey: "YOUR_API_KEY",
      baseURL: "https://api.perplexity.ai"
    });

    const resp = await client.chat.completions.create({
      model: "sonar-pro",
      messages: [{ role: "user", content: "Hello!" }]
    });
    console.log(resp.choices[0].message.content);
    ```
  </Tab>
</Tabs>

<Check>
  Your responses will match OpenAI's format exactly. See the [response structure](#response-structure) section below for complete field details.
</Check>

## API compatibility

### Standard OpenAI parameters

These parameters work exactly the same as OpenAI's API:

* `model` - Model name (use Perplexity model names)
* `messages` - Chat messages array
* `temperature` - Sampling temperature (0-2)
* `max_tokens` - Maximum tokens in response
* `top_p` - Nucleus sampling parameter
* `frequency_penalty` - Frequency penalty (-2.0 to 2.0)
* `presence_penalty` - Presence penalty (-2.0 to 2.0)
* `stream` - Enable streaming responses

### Perplexity-specific parameters

These Perplexity-specific parameters are also included:

* `search_domain_filter` - Limit or exclude specific domains
* `search_recency_filter` - Filter by content recency
* `return_images` - Include image URLs in response
* `return_related_questions` - Include related questions
* `search_mode` - "web" (default) or "academic" mode selector.

## Response structure

Perplexity API responses include both standard OpenAI fields and additional search metadata:

### Standard OpenAI Fields

* `choices[0].message.content` - The AI-generated response
* `model` - The model name used
* `usage` - Token consumption details
* `id`, `created`, `object` - Standard response metadata

### Perplexity-Specific Fields

* `search_results` - Array of web sources with titles, URLs, and dates
* `usage.search_context_size` - Search context setting used

<Tabs>
  <Tab title="Python">
    ```python
    # Access the main response
    content = response.choices[0].message.content
    print(content)

    # Access search sources
    for result in response.search_results:
        print(f"Source: {result['title']}")
        print(f"URL: {result['url']}")
        print(f"Date: {result['date']}")
        print("---")

    # Check token usage
    print(f"Tokens used: {response.usage.total_tokens}")
    ```
  </Tab>

  <Tab title="TypeScript">
    ```typescript
    // Access the main response
    const content = response.choices[0].message.content;
    console.log(content);

    // Access search sources
    response.search_results.forEach(result => {
        console.log(`Source: ${result.title}`);
        console.log(`URL: ${result.url}`);
        console.log(`Date: ${result.date}`);
        console.log("---");
    });

    // Check token usage
    console.log(`Tokens used: ${response.usage.total_tokens}`);
    ```
  </Tab>
</Tabs>

<Info>
  Search results are returned even when streaming is enabled, but they arrive in the final chunk of the stream. See the [Streaming Guide](/guides/streaming) for details.
</Info>

## Unsupported and notable differences

While compatibility is high, note the following differences from OpenAI:

* **Model names**: Use Perplexity models like `sonar-pro`, `sonar-reasoning`.
* **Search controls**: Perplexity adds web/academic search parameters via `extra_body` (Python) or root fields (TypeScript) as shown above.

<Warning>
  If you previously used OpenAI-only fields that aren't applicable to Perplexity search controls, remove or ignore them. Check the API Reference for the current list of supported fields.
</Warning>

## Technical notes

* **Error format**: Same as OpenAI's API for compatibility
* **Rate limiting**: Apply standard rate limiting practices
* **Model names**: Use Perplexity model names (`sonar-pro`, `sonar-reasoning`, etc.)
* **Authentication**: Use `Bearer` token format in Authorization header

# Date and Time Filter Guide
Source: https://docs.perplexity.ai/guides/date-range-filter-guide



<Note>
  The `search_after_date_filter` and `search_before_date_filter` parameters allow you to restrict search results to a specific publication date range. Only results with publication dates falling between these dates will be returned.

  The `last_updated_after_filter` and `last_updated_before_filter` parameters allow you to filter by when content was last modified or updated, rather than when it was originally published.

  The `search_recency_filter` parameter provides a convenient way to filter results by predefined time periods (e.g., "day", "week", "month", "year") relative to the current date.
</Note>

<Info>
  Specific date filters must be provided in the "%m/%d/%Y" format (e.g., "3/1/2025"). Recency filters use predefined values like "day", "week", "month", or "year". All filters are optional—you may supply either specific dates or recency filters as needed.
</Info>

## Overview

Date and time filters allow you to control which search results are returned by limiting them to specific time periods. There are three types of date and time filters available:

### Publication Date Filters

The `search_after_date_filter` and `search_before_date_filter` parameters filter results based on when content was **originally created or published**. This is useful when you need to:

* Find content published within a specific timeframe
* Exclude outdated or overly recent publications
* Focus on content from a particular publication period

### Last Updated Date Filters

The `last_updated_after_filter` and `last_updated_before_filter` parameters filter results based on when content was **last modified or updated**. This is useful when you need to:

* Find recently updated or maintained content
* Exclude stale content that hasn't been updated recently
* Focus on content that has been refreshed within a specific period

### Search Recency Filter

The `search_recency_filter` parameter provides a simple way to filter results by predefined time periods relative to the current date. This is useful when you need to:

* Find content from the past day, week, month, or year
* Get recent results without specifying exact dates
* Quickly filter for timely information

**Available values:**

* `"day"` - Content from the past 24 hours
* `"week"` - Content from the past 7 days
* `"month"` - Content from the past 30 days
* `"year"` - Content from the past 365 days

**Important:** These filter types target different dates—publication filters use the original creation/publication date, while last updated filters use the modification date, and recency filters use a relative time period from the current date.

To constrain search results by publication date:

```bash
"search_after_date_filter": "3/1/2025",
"search_before_date_filter": "3/5/2025"
```

To constrain search results by last updated date:

```bash
"last_updated_after_filter": "3/1/2025",
"last_updated_before_filter": "3/5/2025"
```

To constrain search results by recency:

```bash
"search_recency_filter": "week"
```

These filters will be applied in addition to any other search parameters (for example, domain filters).

## Examples

**1. Limiting Results by Publication Date Range**

This example limits search results to content published between March 1, 2025, and March 5, 2025.

**Request Example**

<CodeGroup>
  ```bash cURL
  curl --location 'https://api.perplexity.ai/chat/completions' \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar",
      "messages": [
        {"role": "system", "content": "You are an expert on current events."},
        {"role": "user", "content": "Show me tech news published this week."}
      ],
      "search_after_date_filter": "3/1/2025",
      "search_before_date_filter": "3/5/2025"
  }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-pro",
      "messages": [
          {"role": "system", "content": "You are an expert on current events."},
          {"role": "user", "content": "Show me tech news published this week."}
      ],
      "search_after_date_filter": "3/1/2025",
      "search_before_date_filter": "3/5/2025"
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```
</CodeGroup>

**2. Filtering with a Single Publication Date Parameter**

If you only wish to restrict the results to those published on or after a specific date, include just the `search_after_date_filter`:

```bash
payload = {
    "model": "sonar-pro",
    "messages": [
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Show me news articles published after March 1, 2025."}
    ],
    "search_after_date_filter": "3/1/2025"
}
```

**3. Filtering by Last Updated Date Range**

This example limits search results to content that was last updated between March 1, 2025, and March 5, 2025. This is useful for finding recently maintained or refreshed content.

**Request Example**

<CodeGroup>
  ```bash cURL
  curl --location 'https://api.perplexity.ai/chat/completions' \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar-pro",
      "messages": [
        {"role": "system", "content": "You are an expert on current events."},
        {"role": "user", "content": "Show me recently updated tech articles."}
      ],
      "last_updated_after_filter": "3/1/2025",
      "last_updated_before_filter": "3/5/2025"
  }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-pro",
      "messages": [
          {"role": "system", "content": "You are an expert on current events."},
          {"role": "user", "content": "Show me recently updated tech articles."}
      ],
      "last_updated_after_filter": "3/1/2025",
      "last_updated_before_filter": "3/5/2025"
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```
</CodeGroup>

**4. Combining Publication and Last Updated Filters**

You can combine both filter types to find content that was published in one timeframe and updated in another:

```bash
payload = {
    "model": "sonar-pro",
    "messages": [
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Show me articles published last year but updated recently."}
    ],
    "search_after_date_filter": "1/1/2024",
    "search_before_date_filter": "12/31/2024",
    "last_updated_after_filter": "3/1/2025"
}
```

**5. Using Search Recency Filter**

The `search_recency_filter` provides a convenient way to filter results by predefined time periods without specifying exact dates:

<CodeGroup>
  ```bash cURL
  curl --location 'https://api.perplexity.ai/chat/completions' \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar-pro",
      "messages": [
        {"role": "system", "content": "You are an expert on current events."},
        {"role": "user", "content": "What are the latest AI developments?"}
      ],
      "search_recency_filter": "week"
  }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-pro",
      "messages": [
          {"role": "system", "content": "You are an expert on current events."},
          {"role": "user", "content": "What are the latest AI developments?"}
      ],
      "search_recency_filter": "week"
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```
</CodeGroup>

This example will return only content from the past 7 days, automatically calculated from the current date.

## Best Practices

**Date Format**

* Strict Format: Dates must match the “%m/%d/%Y” format exactly. For example, the date “3/1/2025” or “03/01/2025” is acceptable.
* Consistency: Use one or both filters consistently based on your search needs. Combining both provides a clear range.

**Filter Selection**

* Choose the Right Filter Type: Use publication date filters (`search_after_date_filter`/`search_before_date_filter`) when you care about when content was originally created. Use last updated filters (`last_updated_after_filter`/`last_updated_before_filter`) when you need recently maintained content. Use recency filters (`search_recency_filter`) for quick, relative time filtering.
* Recency vs. Exact Dates: Use `search_recency_filter` for convenience when you want recent content (e.g., "past week"). Use specific date filters when you need precise control over the time range.
* Combining Filters: You can use both publication and last updated filters together to find content that meets both criteria (e.g., published in 2024 but updated recently). Note that `search_recency_filter` cannot be combined with other date filters.

**Client-Side Validation**

* Regex Check: Validate date strings on the client side (or via the API) using a regex such as:

<CodeGroup>
  ```bash
  date_regex='^(0?[1-9]|1[0-2])/(0?[1-9]|[12][0-9]|3[01])/[0-9]{4}$'
  ```

  ```python
  date_regex = r'^(0?[1-9]|1[0-2])/(0?[1-9]|[12]\d|3[01])/\d{4}$'
  ```
</CodeGroup>

This ensures that dates conform to the required format before sending the request.

**Performance Considerations**

* Narrowing the Search: Applying date range filters typically reduces the number of results, which may improve response times and result relevance.
* Avoid Over-Restriction: Ensure that the date range is neither too narrow (limiting useful results) nor too broad (defeating the purpose of the filter).

⸻

## Last Updated Date Filters

The `last_updated_after_filter` and `last_updated_before_filter` parameters provide powerful filtering capabilities based on when content was last modified or updated, rather than when it was originally published. This is particularly useful for finding recently maintained, refreshed, or updated content.

### Parameters

**`last_updated_after_filter`**

* Filters search results to only include content last updated after this date
* Format should be %m/%d/%Y (e.g. 3/1/2025)
* Optional parameter

**`last_updated_before_filter`**

* Filters search results to only include content last updated before this date
* Format should be %m/%d/%Y (e.g. 3/1/2025)
* Optional parameter

### Use Cases

**Content Freshness**: Find articles, documentation, or resources that have been recently updated to ensure you're getting the most current information.

**Maintenance Tracking**: Identify which content has been actively maintained within a specific timeframe.

**Quality Assurance**: Focus on content that has been refreshed recently, which often indicates higher quality and relevance.

### Code Examples

**1. Find Recently Updated Content (After a Specific Date)**

<CodeGroup>
  ```bash cURL
  curl --location 'https://api.perplexity.ai/chat/completions' \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar-pro",
      "messages": [
        {"role": "system", "content": "You are a helpful assistant focused on current information."},
        {"role": "user", "content": "Find me documentation that has been updated recently."}
      ],
      "last_updated_after_filter": "1/1/2025"
  }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-pro",
      "messages": [
          {"role": "system", "content": "You are a helpful assistant focused on current information."},
          {"role": "user", "content": "Find me documentation that has been updated recently."}
      ],
      "last_updated_after_filter": "1/1/2025"
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```

  ```javascript javascript
  const response = await fetch('https://api.perplexity.ai/chat/completions', {
    method: 'POST',
    headers: {
      'Authorization': 'Bearer YOUR_API_KEY',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      model: 'sonar-pro',
      messages: [
        {role: 'system', content: 'You are a helpful assistant focused on current information.'},
        {role: 'user', content: 'Find me documentation that has been updated recently.'}
      ],
      last_updated_after_filter: '1/1/2025'
    })
  });

  const data = await response.json();
  console.log(data);
  ```
</CodeGroup>

**2. Find Content Updated Within a Specific Window**

<CodeGroup>
  ```bash cURL
  curl --location 'https://api.perplexity.ai/chat/completions' \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar-pro",
      "messages": [
        {"role": "system", "content": "You are an expert on technology trends."},
        {"role": "user", "content": "Show me tech articles that were updated last week."}
      ],
      "last_updated_after_filter": "2/24/2025",
      "last_updated_before_filter": "3/3/2025"
  }' | jq
  ```

  ```python python
  import requests
  from datetime import datetime, timedelta

  # Calculate dates for last week
  today = datetime.now()
  week_ago = today - timedelta(days=7)

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-pro",
      "messages": [
          {"role": "system", "content": "You are an expert on technology trends."},
          {"role": "user", "content": "Show me tech articles that were updated last week."}
      ],
      "last_updated_after_filter": week_ago.strftime("%m/%d/%Y"),
      "last_updated_before_filter": today.strftime("%m/%d/%Y")
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```
</CodeGroup>

**3. Exclude Recently Updated Content (Before a Date)**

<CodeGroup>
  ```bash cURL
  curl --location 'https://api.perplexity.ai/chat/completions' \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar-pro",
      "messages": [
        {"role": "system", "content": "You are a research assistant."},
        {"role": "user", "content": "Find historical content that hasn'\''t been updated recently."}
      ],
      "last_updated_before_filter": "1/1/2024"
  }' | jq 
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-pro",
      "messages": [
          {"role": "system", "content": "You are a research assistant."},
          {"role": "user", "content": "Find historical content that hasn't been updated recently."}
      ],
      "last_updated_before_filter": "1/1/2024"
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```
</CodeGroup>

### Advanced Usage Patterns

**Combining with Domain Filters**

```python
payload = {
    "model": "sonar-pro",
    "messages": [
        {"role": "user", "content": "Latest updates on AI research."}
    ],
    "search_domain_filter": ["arxiv.org", "openai.com"],
    "last_updated_after_filter": "2/1/2025"
}
```

**Finding Maintained vs. Stale Content**

```python
# Find actively maintained content
recent_payload = {
    "model": "sonar-pro",
    "messages": [
        {"role": "user", "content": "Current best practices for React development."}
    ],
    "last_updated_after_filter": "1/1/2025"
}

# Find potentially outdated content
stale_payload = {
    "model": "sonar-pro",
    "messages": [
        {"role": "user", "content": "React development practices."}
    ],
    "last_updated_before_filter": "1/1/2023"
}
```

### Tips for Last Updated Filters

1. **Content Freshness Strategy**: Use `last_updated_after_filter` when you need the most current information on rapidly evolving topics.

2. **Quality Indicator**: Recently updated content often indicates active maintenance and higher reliability.

3. **Research Applications**: Combine with publication date filters to find content published years ago but updated recently, indicating ongoing relevance.

4. **Performance**: These filters can significantly improve response relevance by focusing on maintained content.

5. **Date Selection**: Choose update date ranges based on your content type - technical documentation might need monthly updates, while academic papers might be updated annually.


# Image Filters Guide
Source: https://docs.perplexity.ai/guides/image-filter-guide

Control image results with domain and format filters using the Perplexity API.

<Note>
  The `image_domain_filter` and `image_format_filter` parameters allow you to control the sources and file types of image results returned by the Sonar models.
</Note>

<Warning>
  You can include a maximum of 10 entries in each of the filter lists. These filters currently apply only when `"return_images": true` is set in your request.
</Warning>

## Overview

The `image_domain_filter` and `image_format_filter` parameters give you fine-grained control over image results returned by the Sonar models. Use these filters to:

* Exclude specific image providers (e.g., Getty Images)
* Restrict to a specific file format (e.g., `.gif`)

To use these filters, your request must include `"return_images": true`.

```json
{
  "image_domain_filter": ["-gettyimages.com"],
  "image_format_filter": ["gif"]
}
```

•	Prefix domains with - to exclude them
•	Use lowercase file extensions like gif, jpg, or png
⸻

## Examples

### 1. Exclude Specific Image Domains

This request filters out images from Getty Images.

<CodeGroup>
  ```cURL cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar",
      "return_images": true,
      "image_domain_filter": ["-gettyimages.com"],
      "messages": [
        {"role": "user", "content": "What is the weather like today in London?"}
      ]
    }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
    "model": "sonar",
    "return_images": True,
    "image_domain_filter": ["-gettyimages.com"],
    "messages": [
      {"role": "user", "content": "Show me images of Mount Everest"}
    ]
  }

  response = requests.post(url, headers=headers, json=payload).json()
  print(response["choices"][0]["message"]["content"])
  ```
</CodeGroup>

⸻

### 2. Only Return GIFs

This request restricts results to GIF images.

<CodeGroup>
  ```cURL cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar",
      "return_images": true,
      "image_format_filter": ["gif"],
      "messages": [
        {"role": "user", "content": "Show me a funny cat gif"}
      ]
    }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
    "model": "sonar",
    "return_images": True,
    "image_format_filter": ["gif"],
    "messages": [
      {"role": "user", "content": "Show me a funny cat gif"}
    ]
  }

  response = requests.post(url, headers=headers, json=payload).json()
  print(response["choices"][0]["message"]["content"])
  ```
</CodeGroup>

⸻

## 3. Combine Domain and Format Filters

You can combine both filters for precise control.

<CodeGroup>
  ```cURL cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar",
      "return_images": true,
      "image_domain_filter": ["-gettyimages.com"],
      "image_format_filter": ["gif"],
      "messages": [
        {"role": "user", "content": "Show me a gif of a dog"}
      ]
    }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
    "model": "sonar",
    "return_images": True,
    "image_domain_filter": ["-gettyimages.com"],
    "image_format_filter": ["gif"],
    "messages": [
      {"role": "user", "content": "Show me a gif of a dog"}
    ]
  }

  response = requests.post(url, headers=headers, json=payload).json()
  print(response["choices"][0]["message"]["content"])
  ```
</CodeGroup>

⸻

## Best Practices

**Domain Filtering**
•	Use simple domain names like example.com or -gettyimages.com
•	Do not include http\://, https\://, or subdomains

**Format Filtering**
•	File extensions must be lowercase: \["jpg"], not \["JPG"]
•	Omit dot prefix: use gif, not .gif

**Filter Strategy**
•	You can mix inclusion and exclusion in domain filters
•	Keep lists short (≤10 entries) for performance and relevance

**Performance Notes**
•	Filters may slightly increase response time
•	Overly restrictive filters may reduce result quality or quantity


# Image Guide
Source: https://docs.perplexity.ai/guides/image-guide

Learn how to use Sonar's image upload feature.

<Note>
  The image upload feature allows you to include images in your API requests to support multi-modal conversations alongside text. Images can be provided either as base64 encoded strings within a data URI or as standard HTTPS URLs.
</Note>

<Warning>
  * When using base64 encoding, the API currently only supports images up to 50 MB per image.
  * Supported formats for base64 encoded images: PNG (image/png), JPEG (image/jpeg), WEBP (image/webp), and GIF (image/gif).
  * When using an HTTPS URL, the model will attempt to fetch the image from the provided URL. Ensure the URL is publicly accessible.
</Warning>

Image uploads can be useful for:

* Asking questions about visual content (e.g., text in a screenshot, diagram interpretation)
* Providing context for follow-up queries
* Analyzing visual media as part of a multi-turn conversation

⸻

## Overview

To include an image in a request, you can either:

1. Encode the image as a base64 string and embed it in a data URI using the following format:
   ```bash
   data:image/png;base64,<BASE64_ENCODED_IMAGE>
   ```
   Replace `image/png` with the correct MIME type if you're using JPEG or GIF (`image/jpeg` or `image/gif`).
2. Provide a standard HTTPS URL pointing directly to the image file:
   ```
   https://example.com/path/to/your/image.png
   ```

This data URI or HTTPS URL should be included in your API request as part of a `messages` array, using the `image_url` content type.

⸻

## Request Format

Images must be embedded in the `messages` array, alongside any text input. Each image should be provided using the following structure:

**Using Base64 Data URI:**

```json
{
  "type": "image_url",
  "image_url": {
    "url": "data:image/png;base64,<BASE64_ENCODED_IMAGE>"
  }
}
```

**Using HTTPS URL:**

```json
{
  "type": "image_url",
  "image_url": {
    "url": "https://example.com/path/to/your/image.png"
  }
}
```

⸻

## Examples

<Tabs>
  <Tab title="Base64 Encoding">
    <Info>Use this method when you have the image file locally and want to embed it directly into the request payload. Remember the 5MB size limit and supported formats (PNG, JPEG, WEBP, GIF).</Info>

## Pricing

Images are tokenized based on their pixel dimensions using the following formula:

```
tokens = (width px × height px) / 750
```

For example:

* A 1024×768 image would consume: (1024 × 768) / 750 = 1,048 tokens
* A 512×512 image would consume: (512 × 512) / 750 = 349 tokens

These image tokens are then priced according to the input token pricing of the model you're using (e.g., `sonar-pro`, `sonar`, etc.). The image tokens are added to your total token count for the request alongside any text tokens.

<Warning>
  * Image and regex cannot be used together in the same request.
  * `sonar-deep-research` does not support image input.
  * Ensure provided HTTPS URLs are publicly accessible.
</Warning>


# Integrating MCP with Perplexity's Sonar API
Source: https://docs.perplexity.ai/guides/mcp-server

Learn about the MCP server implementation for the Sonar API.

## What is MCP?

The **Model Context Protocol (MCP)** is an open standard designed to connect AI assistants with the systems where data lives. By providing a universal interface for AI applications to access structured and unstructured data, MCP eliminates the need for custom integrations, enabling AI models to retrieve real-time, relevant information more efficiently. Learn more about MCP [here](https://modelcontextprotocol.io/introduction).

## MCP Server for Perplexity's Sonar API

Our **MCP server implementation** for Sonar allows any AI-powered tool to perform real-time, web-wide research using Perplexity’s powerful search engine. This server acts as a bridge between AI applications and the Sonar, enabling seamless integration for retrieving and synthesizing relevant, up-to-date information from the web.

### How It Works

* The **Perplexity Ask MCP Server** follows MCP’s **open standard**, allowing any AI assistant or automation tool to connect to the **Sonar API** for live web searches.
* AI models can query the server for information retrieval, leveraging Perplexity’s search capabilities to return the most relevant insights.

### Example: Using MCP with Claude

Claude is one example of how this MCP server can be used effectively. When connected to Claude, the **Perplexity Ask MCP Server** enables it to **perform live web searches** and return **highly relevant, up-to-date responses**, enhancing its ability to provide real-time knowledge.

### Where to Find the Documentation

Developers looking to integrate and deploy the **Perplexity Ask MCP Server** can find our implementation, detailed documentation, and setup instructions in our official MCP repository:

📖 [**Perplexity Ask MCP Server**](https://github.com/ppl-ai/modelcontextprotocol/tree/main)

This includes:

* Implementation code
* Setup instructions
* Configuration steps
* API usage guidelines
* Deployment and troubleshooting tips

## Error Handling

### Common Issues

| Error                | Cause                   | Solution                                  |
| -------------------- | ----------------------- | ----------------------------------------- |
| `Invalid URL`        | URL not accessible      | Verify URL returns PDF directly           |
| `File too large`     | PDF exceeds size limits | Compress or split the document            |
| `Processing timeout` | Document too complex    | Simplify question or use smaller sections |

### Example Error Handling

<CodeGroup>
  ```bash cURL
  # Basic error handling with curl
  response=$(curl -s -w "\n%{http_code}" -X POST "https://api.perplexity.ai/chat/completions" \
    -H "Authorization: Bearer YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "messages": [{"content": [{"type": "text", "text": "Analyze this PDF"}], "role": "user"}],
      "model": "sonar-pro"
    }')

  http_code=$(echo "$response" | tail -n1)
  content=$(echo "$response" | head -n -1)

  if [ "$http_code" -eq 200 ]; then
      echo "Success: $content"
  else
      echo "Error $http_code: $content"
  fi
  ```

  ```python Python
  try:
      response = requests.post(url, headers=headers, json=payload)
      
      if response.status_code == 200:
          result = response.json()
          print(result["choices"][0]["message"]["content"])
      else:
          print(f"Error {response.status_code}: {response.text}")
          
  except requests.exceptions.RequestException as e:
      print(f"Request failed: {e}")
  ```

  ```javascript JavaScript
  try {
      const response = await fetch(url, {
          method: 'POST',
          headers: headers,
          body: JSON.stringify(payload)
      });
      
      if (response.ok) {
          const result = await response.json();
          console.log(result.choices[0].message.content);
      } else {
          console.error(`Error ${response.status}: ${await response.text()}`);
      }
  } catch (error) {
      console.error('Request failed:', error);
  }
  ```
</CodeGroup>

## Integration Examples

## Pricing

PDF analysis follows standard Sonar pricing based on:

* Input tokens (document content + question)
* Output tokens (AI response)
* Web search usage (if enabled)

<Tip>
  Large PDFs consume more input tokens. Consider the document size when estimating costs.

# Prompt Guide
Source: https://docs.perplexity.ai/guides/prompt-guide



## System Prompt

You can use the system prompt to provide instructions related to style, tone, and language of the response.

<Warning>
  The real-time search component of our models does not attend to the system prompt.
</Warning>

**Example of a system prompt**

```
You are a helpful AI assistant.

Rules:
1. Provide only the final answer. It is important that you do not include any explanation on the steps below.
2. Do not show the intermediate steps information.

Steps:
1. Decide if the answer should be a brief sentence or a list of suggestions.
2. If it is a list of suggestions, first, write a brief and natural introduction based on the original query.
3. Followed by a list of suggestions, each suggestion should be split by two newlines.
```

## User Prompt

You should use the user prompt to pass in the actual query for which you need an answer for. The user prompt will be used to kick off a real-time web search to make sure the answer has the latest and the most relevant information needed.

**Example of a user prompt**

```
What are the best sushi restaurants in the world currently?
```

# Web Search Models: General Prompting Guidelines

Our web search-powered models combine the capabilities of LLMs with real-time web searches. Understanding how they differ from traditional LLMs will help you craft more effective prompts.

## Best Practices for Prompting Web Search Models

<CardGroup cols={2}>
  <Card title="Be Specific and Contextual">
    Unlike traditional LLMs, our web search models require specificity to retrieve relevant search results. Adding just 2-3 extra words of context can dramatically improve performance.

    **Good Example**: "Explain recent advances in climate prediction models for urban planning"

    **Poor Example**: "Tell me about climate models"
  </Card>

  <Card title="Avoid Few-Shot Prompting">
    While few-shot prompting works well for traditional LLMs, it confuses web search models by triggering searches for your examples rather than your actual query.

    **Good Example**: "Summarize the current research on mRNA vaccine technology"

    **Poor Example**: "Here's an example of a good summary about vaccines: \[example text]. Now summarize the current research on mRNA vaccines."
  </Card>

  <Card title="Think Like a Web Search User">
    Craft prompts with search-friendly terms that would appear on relevant web pages. Consider how experts in the field would describe the topic online.

    **Good Example**: "Compare the energy efficiency ratings of heat pumps vs. traditional HVAC systems for residential use"

    **Poor Example**: "Tell me which home heating is better"
  </Card>

  <Card title="Provide Relevant Context">
    Include critical context to guide the web search toward the most relevant content, but keep prompts concise and focused.

    **Good Example**: "Explain the impact of the 2023 EU digital markets regulations on app store competition for small developers"

    **Poor Example**: "What are the rules for app stores?"
  </Card>
</CardGroup>

## Web Search Model Pitfalls to Avoid

<CardGroup cols={2}>
  <Card title="Overly Generic Questions">
    Generic prompts lead to scattered web search results and unfocused responses. Always narrow your scope.

    **Avoid**: "What's happening in AI?"

    **Instead**: "What are the three most significant commercial applications of generative AI in healthcare in the past year?"
  </Card>

  <Card title="Traditional LLM Techniques">
    Prompting strategies designed for traditional LLM often don't work well with web search models. Adapt your approach accordingly.

    **Avoid**: "Act as an expert chef and give me a recipe for sourdough bread. Start by explaining the history of sourdough, then list ingredients, then..."

    **Instead**: "What's a reliable sourdough bread recipe for beginners? Include ingredients and step-by-step instructions."
  </Card>

  <Card title="Complex Multi-Part Requests">
    Complex prompts with multiple unrelated questions can confuse the search component. Focus on one topic per query.

    **Avoid**: "Explain quantum computing, and also tell me about regenerative agriculture, and provide stock market predictions."

    **Instead**: "Explain quantum computing principles that might impact cryptography in the next decade."
  </Card>

  <Card title="Assuming Search Intent">
    Don't assume the model will search for what you intended without specific direction. Be explicit about exactly what information you need.

    **Avoid**: "Tell me about the latest developments."

    **Instead**: "What are the latest developments in offshore wind energy technology announced in the past 6 months?"
  </Card>
</CardGroup>

## Handling URLs and Source Information

<Warning>
  **Never ask for URLs or source links in your prompts.** The generative model cannot see the actual URLs from the web search, which means any URLs it provides in the response text are likely to be hallucinated and incorrect.
</Warning>

### The Right Way to Access Sources

URLs and source information are automatically returned in the `search_results` field of the API response. This field contains accurate information about the sources used, including:

* `title`: The title of the source page
* `url`: The actual URL of the source
* `date`: The publication date of the content

**Example of incorrect prompting:**

```
❌ BAD: "From the past 5 days, identify high-potential Canadian news stories... 
For each item, include:
- A clear headline  
- 1–2 sentence summary
- Include a link to a source"
```

**Example of correct prompting:**

```
✅ GOOD: "From the past 5 days, identify high-potential Canadian news stories...
For each item, include:
- A clear headline
- 1–2 sentence summary  
- Why it matters from a thought-leadership perspective"

// Then parse URLs from the search_results field in the API response
```

### Why This Matters

The web search and language generation components work differently:

1. **Web Search Component**: Finds and retrieves content from specific URLs
2. **Language Generation Component**: Processes the retrieved content but doesn't have access to the original URLs
3. **API Response**: Provides both the generated text and the accurate source URLs separately

When you ask for URLs in your prompt, the language model will attempt to generate them based on patterns it has seen, but these will not be the actual URLs that were searched. Always use the `search_results` field for accurate source information.

## Preventing Hallucination in Search Results

<Warning>
  **LLMs are designed to be "helpful" and may attempt to provide answers even when they lack sufficient information.** This can lead to hallucinated or inaccurate responses, especially when asking about sources that Sonar cannot access.
</Warning>

### Understanding the Helpfulness Problem

Large Language Models are trained to be assistive and will often try to provide an answer even when they're not confident about the information. This tendency can be problematic when:

* You request information from sources that Sonar cannot access (e.g., LinkedIn posts, private documents, paywalled content)
* The search doesn't return relevant results for your specific query
* You ask for very recent information that may not be indexed yet

### Common Scenarios That Lead to Hallucination

**Inaccessible Sources:**

```
❌ PROBLEMATIC: "What did the CEO of XYZ company post on LinkedIn yesterday about their new product launch?"
```

*Sonar may not be able to access LinkedIn content, but the model might still attempt to provide an answer based on general knowledge or patterns.*

**Overly Specific Recent Events:**

```
❌ PROBLEMATIC: "What was discussed in the closed-door meeting between Company A and Company B last week?"
```

*Private information that wouldn't be publicly searchable may still get a fabricated response.*

### How to Prevent Hallucination

**Use Explicit Instructions:**
Include clear guidance in your prompts about what to do when information isn't available:

```
✅ GOOD: "Search for recent developments in quantum computing breakthroughs. 
If you are not able to get search results or find relevant information, 
please state that clearly rather than providing speculative information."
```

**Set Clear Boundaries:**

```
✅ GOOD: "Based on publicly available sources from the past week, what are the latest policy changes in Canadian healthcare? 
If no recent information is found, please indicate that no recent updates were discovered."
```

**Request Source Transparency:**

```
✅ GOOD: "Find information about Tesla's latest earnings report. 
Only provide information that you can verify from your search results, 
and clearly state if certain details are not available."
```

### Best Practices for Reliable Results

<CardGroup cols={2}>
  <Card title="Be Explicit About Limitations">
    Always instruct the model to acknowledge when it cannot find information rather than guessing.

    **Example**: "If you cannot find reliable sources for this information, please say so explicitly."
  </Card>

  <Card title="Focus on Accessible Sources">
    Stick to information that is likely to be publicly indexed and searchable.

    **Avoid**: LinkedIn posts, private company documents, closed meetings
    **Prefer**: News articles, public reports, official announcements
  </Card>

  <Card title="Use Conditional Language">
    Frame requests with conditional statements that give the model permission to say "I don't know."

    **Example**: "If available, provide details about... Otherwise, indicate what information could not be found."
  </Card>

  <Card title="Verify with Multiple Queries">
    For critical information, consider breaking complex requests into smaller, more specific queries to verify consistency.

    **Strategy**: Ask the same question in different ways and compare results for consistency.
  </Card>
</CardGroup>

## Use Built-in Search Parameters, Not Prompts

<Tip>
  **Always use Perplexity's built-in search parameters instead of trying to control search behavior through prompts.** API parameters are guaranteed to work and are much more effective than asking the model to filter results.
</Tip>

### Why Built-in Parameters Are Better

When you want to control search behavior—such as limiting sources, filtering by date, or adjusting search depth—use the API's built-in parameters rather than prompt instructions. The search component processes these parameters directly, ensuring reliable and consistent results.

### Common Mistakes: Prompt-Based Control

**❌ Ineffective - Trying to control via prompts:**

```json
{
  "model": "sonar-pro",
  "messages": [
    {
      "role": "user", 
      "content": "Search only on Wikipedia and official government sites for information about climate change policies. Make sure to only look at sources from the past month."
    }
  ]
}
```

### Correct Approach: Use API Parameters

**✅ Effective - Using built-in parameters:**

```json
{
  "model": "sonar-pro",
  "messages": [
    {
      "role": "user", 
      "content": "What are the latest climate change policies?"
    }
  ],
  "search_domain_filter": ["wikipedia.org"]
}
```

### Available Search Parameters

### Benefits of Using Built-in Parameters

<CardGroup cols={2}>
  <Card title="Guaranteed Execution">
    Built-in parameters are processed directly by the search engine, ensuring they're applied correctly every time.
  </Card>

  <Card title="Better Performance">
    Parameters filter results before they reach the language model, leading to more focused and relevant responses.
  </Card>

  <Card title="Cleaner Prompts">
    Keep your prompts focused on what you want the model to generate, not how to search.
  </Card>

  <Card title="Consistent Results">
    API parameters provide predictable behavior across different queries and use cases.
  </Card>
</CardGroup>

### Advanced Techniques

<Tip>
  We recommend for users *not* to tune language parameters such as `temperature`, as the default settings for these have already been optimized.
</Tip>

<CardGroup cols={1}>
  <Card title="Parameter Optimization">
    Adjust model parameters based on your specific needs:

    * **Search Domain Filter**: Limit results to trusted sources for research-heavy queries.
    * **Search Context Size**: Use "high" for comprehensive research questions and "low" for simple factual queries.

    Example configuration for technical documentation:

    ```json
    {
      "search_domain_filter": ["wikipedia.org", "docs.python.org"],
      "web_search_options": {
        "search_context_size": "medium"
      }
    }
    ```
  </Card>
</CardGroup>

### Tips for Different Query Types

| Query Type              | Best Practices                                                                                                                         |
| ----------------------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| **Factual Research**    | • Use specific questions  • Use search domain filters for academic sources  • Consider "high" search context size                      |
| **Creative Content**    | • Provide detailed style guidelines in system prompt  • Specify tone, voice, and audience                                              |
| **Technical Questions** | • Include relevant technical context  • Specify preferred programming language/framework  • Use domain filters for documentation sites |
| **Analysis & Insights** | • Request step-by-step reasoning  • Ask for specific metrics or criteria                                                               |


# Rate Limits & Usage Tiers
Source: https://docs.perplexity.ai/guides/rate-limits-usage-tiers



## What are Usage Tiers?

Usage tiers determine your **rate limits** and access to **beta features** based on your cumulative API spending. As you spend more on API credits over time, you automatically advance to higher tiers with increased rate limits.

<Info>
  You can check your current usage tier by visiting your [API settings page](https://www.perplexity.ai/settings/api).
</Info>

***

## Tier Progression

| Tier       | Total Credits Purchased | Status                       |
| ---------- | ----------------------- | ---------------------------- |
| **Tier 0** | \$0                     | New accounts, limited access |
| **Tier 1** | \$50+                   | Light usage, basic limits    |
| **Tier 2** | \$250+                  | Regular usage                |
| **Tier 3** | \$500+                  | Heavy usage                  |
| **Tier 4** | \$1,000+                | Production usage             |
| **Tier 5** | \$5,000+                | Enterprise usage             |

<Note>
  Tiers are based on **cumulative purchases** across your account lifetime, not current balance.
</Note>

***

## How Tiers Work

* **Automatic advancement** - Tiers increase based on your total lifetime credit purchases
* **Rate limit increases** - Higher tiers get significantly more requests per minute
* **Permanent status** - Once you reach a tier, you keep it (no downgrade)

## What Happens When You Hit Rate Limits?

When you exceed your rate limits:

1. **429 Error** - Your request gets rejected with "Too Many Requests"
2. **Automatic Reset** - Limits reset every minute

<Tip>
  **Best Practices:**

  * Monitor your usage to predict when you'll need higher tiers
  * Consider upgrading your tier proactively for production applications
  * Implement exponential backoff in your code
</Tip>

***

## Upgrading Your Tier

<Steps>
  <Step title="Check Current Tier">
    Visit your [API settings page](https://www.perplexity.ai/settings/api) to see your current tier and total spending.
  </Step>

  <Step title="Purchase More Credits">
    Add credits to your account through the billing section. Your tier will automatically upgrade once you reach the spending threshold.
  </Step>

  <Step title="Verify Upgrade">
    Your new rate limits take effect immediately after the tier upgrade. Check your settings page to confirm.
  </Step>
</Steps>

<Check>
  Higher tiers significantly improve your API experience with increased rate limits, especially important for production applications.

# Search Context Size
Source: https://docs.perplexity.ai/guides/search-context-size-guide



<Note>
  The `search_context_size` parameter allows you to control how much search context is retrieved from the web during query resolution, letting you balance cost and comprehensiveness.
</Note>

<Warning>
  * Default `search_context_size` is `low`
  * Selecting `"high"` increases search costs due to more extensive web retrieval. Use `"low"` when cost efficiency is critical.
</Warning>

## Overview

The `search_context_size` field—passed via the `web_search_options` object—determines how much search context is retrieved by the Sonar models. This setting can help you optimize for either:

* Cost savings with minimal search input (`low`)
* Comprehensive answers by maximizing retrieved information (`high`)
* A balance of both (`medium`)

This flexibility allows teams to tune their API usage to their budget and use case.

To enable this feature, include the web\_search\_options.search\_context\_size parameter in your request payload:

```bash
"web_search_options": {
  "search_context_size": "medium"
}
```

## Best Practices

**Choosing the Right Context Size**

* `low`: Best for short factual queries or when operating under strict token cost constraints.
* `medium`: The default and best suited for general use cases.
* `high`: Use for deep research, exploratory questions, or when citations and evidence coverage are critical.

**Cost Optimization**

* Selecting `low` or `medium` can significantly reduce overall token usage, especially at scale.
* Consider defaulting to `low` for high-volume endpoints and selectively upgrading to `high` for complex user prompts.

Combining with Other Filters

* You can use `search_context_size` alongside other features like `search_domain_filter` to further control the scope of search.
* Combining `medium` with a focused domain filter often gives a good tradeoff between quality and cost.

Performance Considerations

* Larger context sizes may slightly increase response latency due to more extensive search and reranking.
* If you’re batching queries or supporting real-time interfaces, test with different settings to balance user experience and runtime.

## Examples

**1. Minimal Search Context ("low")**

This option limits the search context retrieved for the model, reducing cost per request while still producing useful responses for simpler questions.

## Request

<CodeGroup>
  ```bash cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar",
      "messages": [
        {
          "role": "system",
          "content": "Be precise and concise."
        },
        {
          "role": "user",
          "content": "How many stars are there in our galaxy?"
        }
      ],
      "web_search_options": {
        "search_context_size": "low"
      }
    }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar",
      "messages": [
          {"role": "system", "content": "Be precise and concise."},
          {"role": "user", "content": "How many stars are there in our galaxy?"}
      ],
      "web_search_options": {
          "search_context_size": "low"
      }
  }

  response = requests.post(url, headers=headers, json=payload).json()
  print(response["choices"][0]["message"]["content"])
  ```
</CodeGroup>

**Pro-tip**: Use `low` when cost optimization is more important than answer completeness.

**2. Comprehensive Search Context ("high")**

This option maximizes the amount of search context used to answer the question, resulting in more thorough and nuanced responses.

## Request

<CodeGroup>
  ```bash cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "Authorization: Bearer $SONAR_API_KEY" \

    --data '{
      "model": "sonar",
      "messages": [
        {
          "role": "system",
          "content": "Be precise and concise."
        },
        {
          "role": "user",
          "content": "Explain the economic causes of the 2008 financial crisis."
        }
      ],
      "web_search_options": {
        "search_context_size": "high"
      }
    }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar",
      "messages": [
          {"role": "system", "content": "Be precise and concise."},
          {"role": "user", "content": "Explain the economic causes of the 2008 financial crisis."}
      ],
      "web_search_options": {
          "search_context_size": "high"
      }
  }
  response = requests.post(url, headers=headers, json=payload).json()
  print(response["choices"][0]["message"]["content"])
  ```
</CodeGroup>

**Pro-tip**: Use `high` for research-heavy or nuanced queries where coverage matters more than cost.

# Search Classifier Guide
Source: https://docs.perplexity.ai/guides/search-control-guide

Learn how to control when Sonar searches the web using the search classifier or by disabling search altogether.

## Overview

Sonar models provide powerful web search capabilities, but there are times when you want to control when and how searches are performed. Perplexity offers two main approaches for search control:

* **Search Classifier** - Let AI intelligently decide when to search based on the query context
* **Disable Search** - Turn off web search completely for specific requests

<Info>
  Search control is available across all Sonar models.
</Info>

<Warning>
  Pricing remains the same regardless of whether search is triggered or not. Search control features are designed for performance optimization and user experience, not cost reduction.
</Warning>

## Search Classifier

The search classifier is a trained model that automatically determines whether a web search is necessary based on the context and content of your query. This helps optimize performance and costs by only searching when beneficial.

### How It Works

The classifier analyzes your query and decides whether:

* **Search is needed** - For questions requiring current information, facts, or research
* **Search is unnecessary** - For creative tasks, math problems, or general knowledge that doesn't require real-time data

### When to Use Search Classifier

Use the search classifier when you want to:

* **Improve response speed** - Skip search for queries that don't benefit from it
* **Automatic intelligence** - Let AI decide the best approach for each query
* **Optimal user experience** - Ensure search is only used when it adds value

## Disabling Search Completely

For certain use cases, you may want to disable web search entirely. This is useful when:

* **Offline-like responses** - Get responses based only on training data
* **Creative tasks** - Focus on generation without external influence
* **Deterministic responses** - Ensure consistent outputs based only on training data

### Implementation

  </Step>

  <Step title="Try with a current events query">
    ```python
    payload = {
        "model": "sonar-pro", 
        "messages": [{"role": "user", "content": "Latest AI news this week"}],
        "enable_search_classifier": True
    }
    ```

    <Check>
      The classifier will trigger search for this time-sensitive query.

### Creative Task with Disabled Search

Here's an example of using disabled search for creative content generation:

```python
import requests

payload = {
    "model": "sonar-pro",
    "messages": [
        {
            "role": "user", 
            "content": "Write a short science fiction story about time travel"
        }
    ],
    "disable_search": True,
    "temperature": 0.8
}

response = requests.post(
    "https://api.perplexity.ai/chat/completions",
    headers={
        "authorization": "Bearer your-api-key-here",
        "content-type": "application/json"
    },
    json=payload
)
```

## Troubleshooting

<AccordionGroup>
  <Accordion title="Search classifier not working as expected">
    **Common causes:**

    * API key doesn't have access to classifier features
    * Using an unsupported model
    * Incorrect parameter syntax

    **Solutions:**

    * Verify your API key permissions
    * Ensure you're using a Sonar model
    * Check parameter spelling: `enable_search_classifier`
  </Accordion>

  <Accordion title="Responses seem outdated with disabled search">
    This is expected behavior when search is disabled. The model can only use information from its training data.

    **Solutions:**

    * Re-enable search for queries requiring current information
    * Use search classifier for automatic optimization
    * Clearly document when search is disabled for your users
  </Accordion>
</AccordionGroup>

<Tip>
  Start with the search classifier for most applications, then selectively disable search for specific use cases where you want guaranteed offline-like behavior.

  You can add a maximum of 20 domains or URLs to the `search_domain_filter` list. The filter works in either allowlist mode (include only) or denylist mode (exclude), but not both simultaneously.
</Warning>

<Warning>
  Before adding URLs to your allowlist, test that they are accessible via the API by making a sample request. URLs that are blocked, require authentication, or have access restrictions may not return search results, which can significantly impact response quality when using allowlist mode.
</Warning>

## Overview

The `search_domain_filter` parameter allows you to control which websites are included in or excluded from the search results used by the Sonar models. This feature is particularly useful when you want to:

* Restrict search results to trusted sources
* Filter out specific domains from search results
* Focus research on particular websites

Enabling domain filtering can be done by adding a `search_domain_filter` field in the request:

```
"search_domain_filter": [
  "<domain1>",
  "<domain2>",
  ...
]
```

Each entry in the list can be a domain name or a specific URL. The filter operates in two modes:

* **Allowlist mode**: Include only the specified domains/URLs (no `-` prefix)
* **Denylist mode**: Exclude the specified domains/URLs (use `-` prefix)

## Filtering Capabilities

### Domain-Level Filtering

Filter entire domains for broad control:

```json
// Allowlist: Only search these domains
"search_domain_filter": ["wikipedia.org", "github.com", "stackoverflow.com"]

// Denylist: Exclude these domains  
"search_domain_filter": ["-reddit.com", "-pinterest.com", "-quora.com"]
```

### URL-Level Filtering

Target specific pages or sections for granular control:

```json
// Allowlist: Only search these specific URLs
"search_domain_filter": [
  "https://en.wikipedia.org/wiki/Chess",
  "https://stackoverflow.com/questions/tagged/python",
  "https://docs.python.org/3/tutorial/"
]

// Denylist: Exclude these specific URLs
"search_domain_filter": [
  "-https://en.wikipedia.org/wiki/FIDE_rankings",
  "-https://reddit.com/r/politics"
]
```

This granular approach allows you to:

* Include or exclude specific Wikipedia articles while keeping/removing the rest
* Target particular sections of large sites like Stack Overflow or Reddit
* Filter specific documentation pages or subdirectories

## Examples

### 1. Allowlist Specific Domains

This example shows how to limit search results to only include content from specific domains.

**Request**

<CodeGroup>
  ```bash cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "Authorization: Bearer YOUR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar",
      "messages": [
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Tell me about the James Webb Space Telescope discoveries."}
      ],
      "search_domain_filter": [
        "nasa.gov",
        "wikipedia.org",
        "space.com"
      ]
    }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-reasoning-pro",
      "messages": [
          {"role": "system", "content": "You are a helpful assistant."},
          {"role": "user", "content": "Tell me about the James Webb Space Telescope discoveries."}
      ],
      "search_domain_filter": [
          "nasa.gov",
          "wikipedia.org",
          "space.com"
      ]
  }

  response = requests.post(url, headers=headers, json=payload).json()
  print(response["choices"][0]["message"]["content"])
  ```
</CodeGroup>

**Best Practice**: Use simple domain names (e.g., `wikipedia.org`) without additional elements like `https://` or `www.` prefixes.

### 2. Denylist Specific Domains

This example shows how to exclude specific domains from search results by prefixing the domain name with a minus sign (`-`).

**Request**

<CodeGroup>
  ```bash cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "Authorization: Bearer YOUR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar",
      "messages": [
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "What are the latest advancements in renewable energy?"}
      ],
      "search_domain_filter": [
        "-pinterest.com",
        "-reddit.com",
        "-quora.com"
      ]
    }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-deep-research",
      "messages": [
          {"role": "system", "content": "You are a helpful assistant."},
          {"role": "user", "content": "What are the latest advancements in renewable energy?"}
      ],
      "search_domain_filter": [
          "-pinterest.com",
          "-reddit.com",
          "-quora.com"
      ]
  }

  response = requests.post(url, headers=headers, json=payload).json()
  print(response["choices"][0]["message"]["content"])
  ```
</CodeGroup>

**Best Practice**: Use simple domain names with a minus prefix (e.g., `-pinterest.com`) to exclude domains from search results.

### 3. URL-Level Filtering for Granular Control

This example shows how to exclude specific pages while keeping the rest of the domain accessible.

**Request**

<CodeGroup>
  ```bash cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "Authorization: Bearer YOUR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar-pro",
      "messages": [
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Tell me about chess rankings and tournaments."}
      ],
      "search_domain_filter": [
        "-https://en.wikipedia.org/wiki/FIDE_rankings"
      ]
    }' | jq
  ```

  ```python python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-pro",
      "messages": [
          {"role": "system", "content": "You are a helpful assistant."},
          {"role": "user", "content": "Tell me about chess rankings and tournaments."}
      ],
      "search_domain_filter": [
          "-https://en.wikipedia.org/wiki/FIDE_rankings"
      ]
  }

  response = requests.post(url, headers=headers, json=payload).json()
  print(response["choices"][0]["message"]["content"])
  ```
</CodeGroup>

**Result**: This will search all websites except the specific FIDE rankings Wikipedia page, while keeping all other Wikipedia content accessible.

**Alternative - Allowlist specific URLs only:**

```json
"search_domain_filter": [
  "https://en.wikipedia.org/wiki/Chess",
  "https://en.wikipedia.org/wiki/World_Chess_Championship",
  "https://chess.com"
]
```

This would only search those three specific sources and ignore all other websites.

## Best Practices

### Domain and URL Specification

* **Domain filtering**: Use simple domain names (e.g., `example.com`) without protocol prefixes for broad filtering.
* **URL filtering**: Use complete URLs including protocol (e.g., `https://en.wikipedia.org/wiki/FIDE_rankings`) for specific page targeting.
* **Subdomain behavior**: Using a main domain (e.g., `nytimes.com`) will filter all subdomains as well.
* **Granular control**: URL-level filtering allows you to include/exclude specific pages while keeping the rest of the domain.

### Filter Optimization

* **Be specific**: Use domains/URLs that are most relevant to your query to get the best results.
* **Choose your mode**: Use either allowlist mode (include only) OR denylist mode (exclude), but not both in the same request.
* **Limit filter size**: You can add up to 20 domains or URLs. Using fewer, more targeted entries often yields better results.
* **URL precision**: Use full URLs (including `https://`) when targeting specific pages for maximum precision.

### Performance Considerations

* Adding domain filters may slightly increase response time as the search engine needs to apply additional filtering.
* Overly restrictive domain filters might result in fewer search results, potentially affecting the quality of the response.


# SEC Filings Filter Guide
Source: https://docs.perplexity.ai/guides/sec-guide



<Note>
  The `search_mode: "sec"` parameter allows you to tailor your searches specifically to U.S. Securities and Exchange Commission (SEC) filings, prioritizing official financial documents, disclosures, and regulatory filings from public companies.
</Note>

## Overview

The SEC filter allows users to target their searches specifically to official SEC filings. This is especially useful for investors, analysts, journalists, and professionals who require authoritative financial documents, such as 10-Ks, 10-Qs, 8-Ks, and other regulatory filings, rather than general web content or news articles.

When you activate the SEC filter by setting `search_mode: "sec"`, Perplexity limits results to the SEC's EDGAR database and other reputable sources of regulatory filings, filtering out non-official or general web sources. This ensures that the answers you receive are grounded in official disclosures and regulatory compliance.

## Key Features and Functionality

* **Source Filtering**: Prioritizes SEC filings such as 10-K, 10-Q, 8-K, S-1, and more
* **Regulatory Focus**: Returns results based on official financial and regulatory documents
* **Enhanced Precision**: Provides more accurate and up-to-date information for financial and compliance queries

## Usage Examples

### Basic SEC Filings Search

This example shows how to perform a basic search using the SEC filter.

<CodeGroup>
  ```bash cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "accept: application/json" \
    --header "authorization: Bearer $SONAR_API_KEY" \
    --header "content-type: application/json" \
    --data '{
      "model": "sonar-pro",
      "messages": [{"role": "user", "content": "Prepare me for markets opening."}],
      "search_mode": "sec"
    }' | jq
  ```

  ```python Python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {
      "accept": "application/json",
      "authorization": "Bearer YOUR_API_KEY",
      "content-type": "application/json"
  }
  payload = {
      "model": "sonar-pro",
      "messages": [{"role": "user", "content": "Prepare me for markets opening."}],
      "search_mode": "sec"
  }'

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```

  ```javascript Node.js
  const axios = require('axios');

  const url = "https://api.perplexity.ai/chat/completions";
  const headers = {
    "accept": "application/json",
    "authorization": "Bearer YOUR_API_KEY",
    "content-type": "application/json"
  };
  const payload = {
    "model": "sonar-pro",
    "messages": [{"role": "user", "content": "Prepare me for markets opening."}],
    "stream": false,
    "search_mode": "sec"
  };

  axios.post(url, payload, { headers })
    .then(response => console.log(response.data))
    .catch(error => console.error(error));
  ```
</CodeGroup>

### Combining SEC Mode with Other Parameters

You can combine the SEC filter with other parameters for more refined searches:

<CodeGroup>
  ```bash cURL
  curl --request POST \
    --url https://api.perplexity.ai/chat/completions \
    --header "accept: application/json" \
    --header "authorization: Bearer $SONAR_API_KEY" \
    --header "content-type: application/json" \
    --data '{
      "model": "sonar",
      "messages": [{"role": "user", "content": "Summarize the latest 10-K filings for Apple Inc."}],
      "stream": false,
      "search_mode": "sec",
      "search_after_date_filter": "1/1/2023"
  }' | jq
  ```

  ```python Python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {
      "accept": "application/json",
      "authorization": "Bearer YOUR_API_KEY",
      "content-type": "application/json"
  }
  payload = {
      "model": "sonar-deep-research",
      "messages": [{"role": "user", "content": "Summarize the latest 10-K filings for Apple Inc."}],
      "stream": False,
      "search_mode": "sec",
      "search_after_date_filter": "1/1/2023"
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```
</CodeGroup>

## Recommended Use Cases

The SEC filter is particularly valuable for:

1. **Financial Analysis**: When you need to review official financial statements and disclosures
2. **Regulatory Compliance**: For questions requiring up-to-date regulatory filings and compliance information
3. **Market Research**: When tracking company events, earnings, and risk factors
4. **Due Diligence**: For investors and analysts evaluating public companies

## Best Practices

### Optimizing SEC Filings Searches

* **Be Specific**: Reference the type of filing (e.g., 10-K, 8-K) and company name for more precise results
* **Use Financial Terminology**: Include terms like "earnings," "risk factors," or "management discussion" to target relevant sections
* **Combine with Date Filters**: For the most recent filings, combine with `search_after_date_filter`
* **Adjust Context Size**: Use higher `search_context_size` values for more comprehensive responses

### Limitations

* Availability is limited to filings made public through the SEC's EDGAR system
* Some filings may be delayed or amended after initial publication
* Only covers U.S. public companies and registered entities

# Streaming Responses
Source: https://docs.perplexity.ai/guides/streaming

Learn how to stream real-time using Sonar

## Overview

Streaming allows you to receive partial responses from the Perplexity API as they are generated, rather than waiting for the complete response. This is particularly useful for:

* **Real-time user experiences** - Display responses as they're generated
* **Long responses** - Start showing content immediately for lengthy analyses
* **Interactive applications** - Provide immediate feedback to users

<Info>
  Streaming is supported across all Perplexity models including Sonar, Sonar Pro, and reasoning models.
</Info>

## Quick Start

To enable streaming, add `"stream": true` to your API request:

<Tabs>
  <Tab title="Requests (Python)">
    ```python
    import requests
    import json

    ```
  </Tab>
</Tabs>

### Basic Implementation

With this code snippet, you can stream responses from the Perplexity API using the requests library. However, you will need to parse the response manually to get the content, search results, and metadata.

```python
import requests

# Set up the API endpoint and headers
url = "https://api.perplexity.ai/chat/completions"
headers = {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
}

payload = {
    "model": "sonar-pro",
    "messages": [
        {"role": "user", "content": "Who are the top 5 tech influencers on X?"}
    ],
    "stream": True  # Enable streaming for real-time responses
}

response = requests.post(url, headers=headers, json=payload, stream=True)

# Process the streaming response (simplified example)
for line in response.iter_lines():
    if line:
        print(line.decode('utf-8'))
```

### Streaming Best Practices

<Tabs>
  <Tab title="Gathering Search Results">
    Gather all your search results and metadata in the final chunk of the response neatly in an array.

    ```python
    from openai import OpenAI

    client = OpenAI(
        api_key="YOUR_API_KEY",
        base_url="https://api.perplexity.ai"
    )

    stream = client.chat.completions.create(
        model="sonar-pro",
        messages=[
            {"role": "user", "content": "Compare renewable energy technologies"}
        ],
        stream=True
    )

    content = ""
    search_results = []
    usage_info = None

    for chunk in stream:
        # Content arrives progressively
        if chunk.choices[0].delta.content is not None:
            content_chunk = chunk.choices[0].delta.content
            content += content_chunk
            print(content_chunk, end="")
        
        # Metadata arrives in final chunks
        if hasattr(chunk, 'search_results') and chunk.search_results:
                    search_results = chunk.search_results
        
        if hasattr(chunk, 'usage') and chunk.usage:
            usage_info = chunk.usage
        
        # Handle completion
        if chunk.choices[0].finish_reason is not None:
            print(f"\n\nFinish reason: {chunk.choices[0].finish_reason}")
            print(f"Search Results: {search_results}")
            print(f"Usage: {usage_info}")
    ```

## Search Results and Metadata During Streaming

<Info>
  Search results and metadata are delivered in the **final chunk(s)** of a streaming response, not progressively during the stream.
</Info>

### How Metadata Works with Streaming

When streaming, you receive:

1. **Content chunks** which arrive progressively in real-time
2. **Search results** (delivered in the final chunk(s))
3. **Usage stats**

### Using Requests Library for Metadata

```python
import requests
import json

def stream_with_requests_metadata():
    url = "https://api.perplexity.ai/chat/completions"
    headers = {
        "Authorization": "Bearer YOUR_API_KEY",
        "Content-Type": "application/json"
    }
    payload = {
        "model": "sonar",
        "messages": [{"role": "user", "content": "Explain quantum computing"}],
        "stream": True
    }
    
    response = requests.post(url, headers=headers, json=payload, stream=True)
    
    content = ""
    metadata = {}
    
    for line in response.iter_lines():
        if line:
            line = line.decode('utf-8')
            if line.startswith('data: '):
                data_str = line[6:]
                if data_str == '[DONE]':
                    break
                try:
                    chunk = json.loads(data_str)
                    
                    # Process content
                    if 'choices' in chunk and chunk['choices'][0]['delta'].get('content'):
                        content_piece = chunk['choices'][0]['delta']['content']
                        content += content_piece
                        print(content_piece, end='', flush=True)
                    
                    # Collect metadata
                    for key in ['search_results', 'usage']:
                        if key in chunk:
                            metadata[key] = chunk[key]
                            
                    # Check if streaming is complete
                    if chunk['choices'][0].get('finish_reason'):
                        print(f"\n\nMetadata: {metadata}")
                        
                except json.JSONDecodeError:
                    continue
    
    return content, metadata

stream_with_requests_metadata()
```

<Warning>
  **Important**: If you need search results immediately for your user interface, consider using non-streaming requests for use cases where search result display is critical to the real-time user experience.
</Warning>


# Structured Outputs Guide
Source: https://docs.perplexity.ai/guides/structured-outputs



## Overview

Structured outputs enable you to enforce specific response formats from Perplexity's models, ensuring consistent, machine-readable data that can be directly integrated into your applications without manual parsing.

We currently support two types of structured outputs: **JSON Schema** and **Regex**. LLM responses will work to match the specified format, except for the following cases:

* The output exceeds `max_tokens`

Enabling the structured outputs can be done by adding a `response_format` field in the request:

**JSON Schema**

* `response_format: { type: "json_schema", json_schema: {"schema": object} }` .

* The schema should be a valid JSON schema object.

**Regex** (only available for `sonar` right now)

* `response_format: { type: "regex", regex: {"regex": str} }` .

* The regex is a regular expression string.

<Tip>
  **Improve Schema Compliance**: Give the LLM some hints about the output format in your prompts to improve adherence to the structured format.

  For example, include phrases like "Please return the data as a JSON object with the following structure..." or "Extract the information and format it as specified in the schema."
</Tip>

<Info>
  The first request with a new JSON Schema or Regex expects to incur delay on the first token. Typically, it takes 10 to 30 seconds to prepare the new schema, and may result in timeout errors. Once the schema has been prepared, the subsequent requests will not see such delay.
</Info>

  const data = await response.json();

## Best Practices

### Generating responses in a JSON Format

For Python users, we recommend using the Pydantic library to [generate JSON schema](https://docs.pydantic.dev/latest/api/base_model/#pydantic.BaseModel.model_json_schema).

**Unsupported JSON Schemas**

Recursive JSON schema is not supported. As a result of that, unconstrained objects are not supported either. Here's a few example of unsupported schemas:

```
# UNSUPPORTED!

from typing import Any

class UnconstrainedDict(BaseModel):
   unconstrained: dict[str, Any]

class RecursiveJson(BaseModel):
   value: str
   child: list["RecursiveJson"]
```

<Warning>
  **Links in JSON Responses**: Requesting links as part of a JSON response may not always work reliably and can result in hallucinations or broken links. Models may generate invalid URLs when forced to include links directly in structured outputs.

  To ensure all links are valid, use the links returned in the `citations` or `search_results` fields from the API response. Never count on the model to return valid links directly as part of the JSON response content.
</Warning>

### Generating responses using a regex

**Supported Regex**

* Characters: `\d`, `\w`, `\s` , `.`
* Character classes: `[0-9A-Fa-f]` , `[^x]`
* Quantifiers: `*`, `?` , `+`, `{3}`, `{2,4}` , `{3,}`
* Alternation: `|`
* Group: `( ... )`
* Non-capturing group: `(?: ... )`

**Unsupported Regex**

* Contents of group: `\1`
* Anchors: `^`, `$`, `\b`
* Positive lookahead: `(?= ... )`
* Negative lookahead: `(?! ... )`
* Positive look-behind: `(?<= ... )`
* Negative look-behind: `(?<! ... )`
* Recursion: `(?R)`

## Perplexity's JSON Schema Implementation

Perplexity's structured outputs implementation has several key differences compared to other providers:

### Simplified Schema Definition

* **Optional naming**: Unlike other providers that require explicit schema names, Perplexity automatically handles schema naming with sensible defaults
* **Flexible strictness**: Schema validation is handled automatically without requiring manual strictness configuration
* **Streamlined syntax**: You only need to provide the core schema object without additional wrapper fields

**Other Providers:**

```json
{
  "response_format": {
    "type": "json_schema",
    "json_schema": {
      "name": "financial_data",
      "strict": true,
      "schema": { /* your schema */ }
    }
  }
}
```

**Perplexity:**

```json
{
  "response_format": {
    "type": "json_schema", 
    "json_schema": {
      "schema": { /* your schema */ }
    }
  }
}
```

### Enhanced Error Handling

* **Clear error messages**: When schemas fail validation, you'll receive specific, actionable error messages
* **Recursion protection**: Built-in safeguards prevent infinite recursion in complex nested schemas
* **Constraint validation**: Automatic detection and clear messaging for unsupported features like unconstrained objects

### Schema Compatibility

While Perplexity supports standard JSON Schema syntax, some advanced features may not be available:

* Recursive schemas are not supported for performance and reliability reasons
* Unconstrained objects (like `dict[str, Any]`) are automatically detected and rejected
* Complex reference patterns may require simplification

This approach prioritizes reliability and performance while maintaining compatibility with most common JSON Schema use cases.

## Structured Outputs for Reasoning Models

When using structured outputs with reasoning models like `sonar-reasoning-pro`, the response will include a `<think>` section containing reasoning tokens, immediately followed by the structured output. The `response_format` parameter does not remove these reasoning tokens from the output, so the final response will need to be parsed manually.

**Sample Response:**

```
<think>
I need to provide information about France in a structured JSON format with specific fields: country, capital, population, official_language.

For France:
- Country: France
- Capital: Paris
- Population: About 67 million (as of 2023)
- Official Language: French

Let me format this information as required.
</think>
{"country":"France","capital":"Paris","population":67750000,"official_language":"French"}
```

For a reusable implementation to extract JSON from reasoning model outputs, see our [example utility on GitHub](https://github.com/ppl-ai/api-discussion/blob/main/utils/extract_json_reasoning_models.py).


# User Location Filter Guide
Source: https://docs.perplexity.ai/guides/user-location-filter-guide



<Note>
  The `user_location` parameter within `web_search_options` allows you to refine search results based on the user's approximate geographic location. This helps provide more contextually relevant information.
</Note>

<Info>
  You can specify the location using latitude/longitude coordinates, country code, city, and region. For the most accurate results, we recommend providing as much location information as possible, including `city` and `region` fields. For supported country codes, please refer to the list [here](https://en.wikipedia.org/wiki/List_of_ISO_3166_country_codes).
</Info>

<Tip>
  The `city` and `region` fields significantly improve location accuracy. We strongly recommend including them alongside coordinates and country code for the best results.
</Tip>

<Warning>
  Latitude and longitude must be provided alongside the country parameter, they cannot be provided on their own.
</Warning>

## Overview

The `user_location` filter helps tailor search results by incorporating geographic context. This is particularly useful for queries where location significantly impacts relevance, such as:

* Finding local businesses or services.
* Getting information about regional events or news.
* Understanding location-specific regulations or customs.

To refine search results by location, include the `user_location` object within the `web_search_options` in your request payload. You can provide coordinates, country code, city, region, or combine them for maximum accuracy:

**Using All Available Fields (Recommended for Best Accuracy):**

```json
"web_search_options": {
  "user_location": {
    "country": "US",
    "region": "California",
    "city": "San Francisco",
    "latitude": 37.7749,
    "longitude": -122.4194
  }
}
```

**Using City and Region with Country:**

```json
"web_search_options": {
  "user_location": {
    "country": "US",
    "region": "New York",
    "city": "New York City"
  }
}
```

**Using Latitude/Longitude:**

```json
"web_search_options": {
  "user_location": {
    "country":"US",
    "latitude": 37.7749,
    "longitude": -122.4194
  }
}
```

**Using Country Code Only:**

```json
"web_search_options": {
  "user_location": {
    "country": "US"
  }
}
```

These filters work alongside other search parameters like date range or domain filters.

## Examples

**1. Refining Results with All Location Fields (Recommended)**

This example provides all available location fields for San Francisco to get the most accurate geographically relevant search results.

**2. Refining Results with Country Code**

This example uses a two-letter ISO country code (United States) to provide broader geographic context.

**Request Example**

<CodeGroup>
  ```bash cURL
  curl --location 'https://api.perplexity.ai/chat/completions' \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar-pro",
      "messages": [
        {"role": "system", "content": "You are an expert on international news."},
        {"role": "user", "content": "Summarize political news from today."}
      ],
      "web_search_options": {
        "user_location": {
          "country": "US"
        }
      }
  }' | jq
  ```

  ```python Python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-pro",
      "messages": [
          {"role": "system", "content": "You are an expert on international news."},
          {"role": "user", "content": "Summarize political news from today."}
      ],
      "web_search_options": {
        "user_location": {
          "country": "US"
        }
      }
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```

**3. Using City and Region for Better Accuracy**

This example shows how to use `city` and `region` fields along with coordinates for Paris, France to achieve maximum location accuracy.

**Request Example**

<CodeGroup>
  ```bash cURL
  curl --location 'https://api.perplexity.ai/chat/completions' \
    --header "Authorization: Bearer $SONAR_API_KEY" \
    --header "Content-Type: application/json" \
    --data '{
      "model": "sonar-pro",
      "messages": [
        {"role": "system", "content": "You are an expert on French news and events."},
        {"role": "user", "content": "What major events are happening in the capital this week?"}
      ],
      "web_search_options": {
        "user_location": {
          "country": "FR",
          "region": "Île-de-France",
          "city": "Paris",
          "latitude": 48.8566, 
          "longitude": 2.3522
        }
      }
  }' | jq
  ```

  ```python Python
  import requests

  url = "https://api.perplexity.ai/chat/completions"
  headers = {"Authorization": "Bearer YOUR_API_KEY"}
  payload = {
      "model": "sonar-pro",
      "messages": [
          {"role": "system", "content": "You are an expert on French news and events."},
          {"role": "user", "content": "What major events are happening in the capital this week?"}
      ],
      "web_search_options": {
        "user_location": {
          "country": "FR",
          "region": "Île-de-France",
          "city": "Paris",
          "latitude": 48.8566, 
          "longitude": 2.3522
        }
      }
  }

  response = requests.post(url, headers=headers, json=payload)
  print(response.json())
  ```

## Best Practices

**Choosing the Right Specificity**

* **All Fields (Recommended):** For maximum accuracy, provide country, region, city, latitude, and longitude. This combination gives the best results for location-specific queries.
* **City and Region:** Use these fields to significantly improve location accuracy without needing exact coordinates. Particularly useful for metropolitan areas and regional searches.
* **Latitude/Longitude:** Use for high precision when the exact location is known and relevant (e.g., finding nearby points of interest).
* **Country Code:** Use for broader context when country-level relevance is sufficient (e.g., national news, country-specific regulations).
* **Combining Fields:** We strongly recommend providing as many location fields as possible. Each additional field improves search accuracy and relevance.

**Data Accuracy**

* Ensure the provided location data is as accurate as possible. Incorrect data may lead to irrelevant results.
* Latitude values must be between -90 and 90. Longitude values must be between -180 and 180.
* Country codes should be valid two-letter ISO 3166-1 alpha-2 codes (e.g., "US", "GB", "DE").
* City names should match commonly used names (e.g., "New York City" or "NYC" for New York).
* Region names should match standard administrative divisions (states, provinces, etc.).

**Privacy Considerations**

* Be mindful of user privacy when collecting and transmitting location data. Only use location when necessary and with user consent where applicable.

**Client-Side Validation**

* Consider validating location inputs before sending the request:
  * Check latitude/longitude ranges.
  * Validate country code format (two uppercase letters).
  * Sanitize city and region inputs for special characters.
