Ground code generation across 1B+ webpages

Search documentation and public repositories for examples that use the exact library, method, or API your agent needs. Exa's index covers over 1B webpages, including repositories, docs pages, and changelogs with up-to-date information.

Up-to-date library docs for every coding agent

Keep agents current on every package they use with live documentation from Exa, including changes made after the model's training cutoff. Catch renamed functions, deprecated arguments, and breaking changes before they reach code review.

Give coding agents the context they need with 95% fewer tokens

Exa Highlights select the passages that answer your agent's question across retrieved pages, reducing context tokens by 95% on average compared with full-page content.

Coding agents grounded in the live web

Devin, Cognition's AI software engineer, uses Exa to look up errors, read documentation, and find the right libraries as it writes code.

Common questions

Exa indexes documentation and API references, repositories and issue threads, changelogs and release notes, and technical writing across the open web, alongside a code index of working examples.

Exa returns Highlights, excerpts of pages and documents that answer the agent's query, instead of whole pages. On the Auth.js Google provider docs, a highlight on implementation is about 180 tokens where the full page is about 2,400. Across Exa's evaluations, Dynamic Highlights cut tokens by an average of 95% compared with full pages.

Yes. Set the search type on each request. The lite type returns results in about 450 ms, and auto, the default, in about 1 second. For research questions, deep (4 to 15 seconds) searches in several steps and combines the results.

Yes, for coding agents that work beyond a fixed set of libraries. Context7 serves documentation for the libraries it has indexed, which suits work in predictable, common libraries. Exa searches the live web through Exa MCP, across docs, repositories, issue threads, and changelogs, so agents also find answers for newer libraries and unfamiliar errors more often.

Yes. Claude Code has a built-in web search tool, and Exa's search costs less per query. Add Exa to Claude Code with claude plugin install exa@claude-plugins-official for web search and page contents, including code and documentation search.

In all of these tools, connect Exa's hosted MCP server at https://mcp.exa.ai/mcp, or ask your agent to install Exa MCP and it will handle the rest. No API key is needed to start. Point your agent to the Exa MCP setup guide, which also covers Windsurf, Zed, Gemini CLI, and other clients.

Exa is the search layer embedded in Devin and CodeRabbit. Both use Exa as the knowledge layer that surfaces the latest documentation, libraries, and reference code. Any agent that calls an API or an MCP server can use Exa, including Claude Code, Cursor, and Codex.

Yes. Exa is SOC 2 Type II audited and honors GDPR and CCPA data-subject rights. Enterprise plans offer zero data retention, HIPAA with a BAA, SSO and SCIM, and a custom MSA and DPA. To access audit reports, request them in the Trust Center or talk to our team.

Exa is free to start: the free tier includes $10 in credits each month, and Exa MCP works without an API key on a rate-limited free tier. After that, Exa Search starts at $4 per 1,000 requests, and page contents cost $1 per 1,000 pages.
