Exa

Exa is a web intelligence platform for developers and AI products. Its APIs provide semantic and keyword web search, page contents, crawling, answers, deep research workflows, and monitoring through products such as Search, Contents, Agent, Monitors, and Websets. Developers can use Exa to give coding agents, chatbots, voice agents, and research systems current web information, then retrieve clean page text and structured results for downstream processing.

✨ Key Features

• Use keyword and neural search modes — Select the retrieval style that fits the application.
• Retrieve page contents — Fetch clean text, highlights, summaries, and additional results for selected pages.
• Crawl websites — Collect relevant content from websites for agent and research workflows.
• Build deep research flows — Use Deep Search and Deep-Reasoning Search endpoints for harder information tasks.
• Generate search answers — Use the Answer endpoint to return an answer grounded in retrieved web material.
• Monitor the web — Track searches and receive new matching results through Monitors.
• Create Websets — Enrich and monitor structured collections of web entities for people, companies, and other research targets.
• Support AI agents — Supply fresh web context to coding agents, chatbots, and voice agents.
