Exa
Exa is a web search API and AI research platform built specifically for LLMs and agents — semantic and keyword search across the open web with token-efficient highlights, structured outputs, sub-200ms latency tiers, and verticals for code, companies, news, people, research, and financials. The platform pairs the core Search, Contents, and Answer endpoints with Research (asynchronous deep research), Agent (managed multi-step agents at four effort modes), Monitors (scheduled searches with webhooks), and Websets (curated, enrichable result collections). Customers include Cognition (Devin), HubSpot, Monday, Databricks, AWS, and Cursor; Exa raised a $250M Series C to build the search engine for AIs. Open SDKs in Python and JavaScript, an MCP server, Google Sheets and n8n integrations, and a free tier of 1,000 requests/month round out the surface.
Exa publishes 19 APIs on the APIs.io network, including Agent API, Answer API, Contents API, and 16 more. Tagged areas include AI, Search, Web Search, Neural Search, and LLM.
The Exa catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Exa’s developer surface includes authentication, changelog, developer portal, documentation, getting-started guide, signup flow, sandbox, and 63 more developer resources.
