Exa provides cloud APIs for public-web search, page-content retrieval, deep research, and monitoring. It is designed for developers and organizations adding AI-powered search or retrieval to applications and agents. Search can return webpage text and highlights, while Deep Search supports multi-step workflows, structured outputs, and web-grounded citations. The API also covers searches for people, companies, scholarly works, and general web content.

The Free (Starter) plan includes $10 in monthly credits, a $10 onboarding bonus, no payment method requirement, MCP server access, 50+ integrations, and access to all endpoints. Paid developer pricing is usage-based: Search costs $7 per 1,000 requests, Contents costs $1 per 1,000 pages, Deep Search costs $12 per 1,000 requests, and Monitors costs $15 per 1,000 requests. Contents adds full page contents for LLM context and token-efficient highlights; Deep Search adds multi-step agent workflows and structured outputs; Monitors adds fresh-event detection, scheduled searches, and webhook updates. Enterprise uses custom pricing and includes a custom MSA and DPA, zero data retention, SOC 2 Type II and HIPAA, SSO and SCIM, a dedicated Slack channel, and enterprise SLAs.

Exa fits ecosystems that need an API layer rather than a standalone search destination. Integrations include Claude Connector, ChatGPT plugin, MCP server, n8n, OpenAI, Make, Zapier, LangChain, LlamaIndex, and Vercel AI SDK, with email, documentation, and community support. Its broad endpoint set suits teams building retrieval, research, citation, or monitoring features across small, mid-market, and enterprise deployments. Teams seeking a browser-based research experience or a conventional end-user search interface should choose a different type of product; Exa is most appropriate when developers control the application and can manage usage-based billing.
