Overview
Exa is a web search engine built for AI agents. Its API searches the web in natural language, with categories for company pages and people profiles, returns clean page contents, answers questions with citations, reruns searches on a schedule as monitors, and runs Exa Agent for multi-step research, list building and enrichment with structured output. The hosted MCP server also works without a key at free rate limits. Signing in with OAuth (the `?login` URL) uses your team's plan and turns on `agent_run`; a client without OAuth can send an API key in the `x-api-key` header instead. The API takes the key as a Bearer token or in `x-api-key`. Usage is pay-as-you-go, and new accounts start with free credits.
