# Community Showcase

> Applications developers have built on the Perplexity API Platform.

The Community Showcase highlights applications developers have built on the Agent API and Search API.

Projects built on Sonar Chat Completions were removed from this section when Sonar support ended on September 27, 2026. New submissions are open.

2. Fork the [API Cookbook repository](https://github.com/perplexityai/api-cookbook).
3. Add an MDX write-up under `docs/showcase/` with what the project does, which Perplexity APIs it uses, and screenshots or a demo link.
