Perplexity API

Integrate a real-time, web-grounded LLM (Large Language Model) into your application, delivering current, cited answers and search results.

The Perplexity API grants programmatic access to its search infrastructure and Grounded LLM models, including `sonar-pro` and `sonar-small-online`. Unlike static LLMs, this system executes real-time online searches, ensuring all generated responses are current, factually grounded, and include verifiable citations. Developers utilize the OpenAI-compatible chat completions endpoint or the dedicated Search API to embed unparalleled, web-wide research and Q&A capabilities directly into their products.
