The Perplexity API Platform is a suite of models and endpoints designed to power new applications.
Our dedicated developer documentation can be found at API Platform
Search API offers programmatic access to the same global-scale retrieval infrastructure that powers Perplexity’s public answer engine, with an index spanning hundreds of billions of webpages. It returns ranked, structured results optimized for AI use cases and supports options like regional targeting and multi-query requests for efficient research workflows.
Sonar is the family of fast, cost-efficient, web-grounded models exposed via the API that produce cited answers and support source customization for higher control and trust.
For setup and first calls, see the Quickstart in the developer documentation.
