Introducing the Perplexity Search API

Perplexity has launched its Search API, giving developers access to the global-scale search infrastructure behind its public answer engine and an index spanning hundreds of billions of webpages. Designed for AI and conventional applications, the API returns structured, fine-grained and ranked content snippets rather than only document-level results, reducing preprocessing and improving downstream relevance. Perplexity says its infrastructure emphasizes accuracy, source-backed information, and real-time freshness through tens of thousands of index updates per second and AI-driven web-content parsing that adapts using evaluations and user-query signals. The company also released a Search SDK, an API platform, documentation, and the open-source search_evals framework for comparing public search APIs on quality and latency. Perplexity positions the offering as a lower-cost, high-performance and easy-to-integrate option for developers, researchers, enterprises, and startups building internet-scale search and AI-agent capabilities.
