Exa is an applied AI lab building a web search API designed for AI agents. Its Search API returns ranked, token-efficient results with highlights and page contents, while Deep Search reasons across sources and returns structured outputs grounded in citations. The Agent API runs asynchronous deep research, list building, and enrichment, and Monitors track fresh web events on a schedule. Developers use Exa to ground coding agents, chatbots, GTM workflows, and research pipelines in current web data. Access starts with free monthly credits, with pay-as-you-go and custom enterprise plans available.
