Exa

What Exa is

Exa Labs builds a web search engine for AI systems. Agents, chatbots, coding assistants and data pipelines call its APIs and get back ranked results, page text, token-efficient highlights, structured fields or cited answers.

Products

• Search API: Lite (~450 ms), Auto (~1 s) and Deep (~10 s) search, with news, company, research, people and financial categories.
• Contents API: full page text, highlights and summaries with live-crawl controls.
• Agent API and Websets: asynchronous deep research and list-building with structured, cited outputs.
• Monitors API (v2): scheduled searches that remember what was already sent and deliver only new, relevant results to your webhook as a summary or JSON, now $2 per 1,000 runs (down from $15).
• Exa Connect, MCP server, Claude connector, ChatGPT plugin and 50+ integrations.
