EXA

EXA is a web search API and AI web researcher built to provide AI applications with high-quality, up-to-date information from the open web. Instead of relying on static datasets, Exa helps developers retrieve relevant sources in real time, crawl and extract page content, and use those results to generate grounded answers. It’s designed for business-grade search and crawling, making it suitable for production workflows where coverage, freshness, and structured outputs matter.

Through Exa’s API, you can run web searches, fetch full page contents, and retrieve useful metadata and summaries for URLs. This makes it easier to build RAG pipelines, research agents, monitoring tools, and analytics systems that need reliable web evidence. Exa also offers “LLM Answers,” which lets you ask a question and receive a response informed by Exa search results, helping reduce hallucinations by tying outputs to retrieved sources.

For teams that need to find and enrich sets of entities (for example, companies or people), Exa Websets supports data discovery and enrichment for workflows like sales prospecting, recruiting, and market research. Exa is based in San Francisco, and support is available via [email protected] or through their contact page at https://cal.com/team/exa/exa-intro-chat.
