Exa

Exa is a search API built for AI agents rather than people. It indexes the public web along with people, company and scholarly datasets, and returns raw results, a direct answer or structured output from a single endpoint. Latency is configurable, from an instant tier returning in well under a second to deep research runs that take around ten seconds, so an agent can trade speed against thoroughness per call. It is aimed at developers building coding agents, chatbots, research tools, sales enrichment and news monitoring. The product line covers a Search API, a Contents API that returns full page text and token efficient highlights with configurable live crawl policies, an Agent API for asynchronous deep research with citations and structured outputs, and a Monitors API that reruns a search on a schedule to surface fresh events. Access routes include an MCP server, a Claude connector, a ChatGPT plugin and more than fifty integrations, while Exa Connect adds external data providers. Enterprise terms cover zero data retention, HIPAA, custom indexes and custom rate limits. Pricing is published per request. Starter is free, with $10 of credits each month plus a $10 onboarding bonus and no payment method required. Developer is usage based: Search from $4 per thousand requests, Contents at $1 per thousand pages per content type, Deep Search at $12 to $15 per thousand requests, and Monitors at $15 per thousand requests. Agent runs cost $0.012 to $1.00 each depending on effort level, with compute units at $0.10 and search tool calls at $0.005. Enterprise pricing is custom. Exa describes itself as an applied AI lab and recently added Exa Places, an index covering 211 million places.
