This page shows pricing information to help you understand API costs. For billing setup, payment methods, and usage monitoring, visit the Admin section.
Total cost per query = Token costs + Request fee (varies by search context size, applies to Sonar, Sonar Pro, Sonar Reasoning, and Sonar Reasoning Pro models only)
Token Pricing
Token pricing is based on the number of tokens in your request and response.| Model | Input Tokens ($/1M) | Output Tokens ($/1M) | Citation Tokens ($/1M) | Search Queries ($/1K) | Reasoning Tokens ($/1M) |
|---|---|---|---|---|---|
| Sonar | $1 | $1 | - | - | - |
| Sonar Pro | $3 | $15 | - | - | - |
| Sonar Reasoning | $1 | $5 | - | - | - |

Token and Cost Glossary
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
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
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 informationSearch 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_effortparameter 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 explanationsToken Calculation: 1 token ≈ 4 characters in English text. The exact count may vary based on language and content complexity.
