Exa - The world's data for AI agents

About Exa

Exa is a tool that provides a search API and related APIs designed for developers building AI agents and applications that need up-to-date web data, deep research, and structured content from one endpoint. It emphasizes serving the needs of AI researchers, developers, and teams building agentic or RAG-enabled systems by delivering passages, structured data, and citations from the live web.

Exa supports embedding and agentic search for contexts like coding, finance, and GTM intelligence, with capabilities to configure token-efficient search, grounded citations, and structured outputs. It highlights enterprise-grade security, privacy, and governance features, as well as a vision of powering high-scale AI workflows with a large, high-quality index of documents and URLs.

Exa promotes its services across multiple APIs (Search API, Contents API, Agent API, Monitors API, Exa Library, Integrations, Exa Connect) and notes its availability to developers and enterprises with options to talk to sales or try for free. It also mentions monitoring, analytics, and partner integrations as part of its ecosystem and deployment options.

because the site's pages describe a software product with APIs, data indexing, and tooling for AI agents, Exa is presented as a software product rather than a generic site.

Frequently asked questions

How do I add web search to my LLM app or assistant?

Add Exa as a tool your model can call. When a question needs current information, your app sends it to Exa, and Exa returns ranked pages with their URLs, dates, and the passages that answer the question, so the model can write its reply with citations for each source.

Does Exa return cited passages instead of full pages?

Yes. With Highlights turned on, Exa returns only the passages from each page that answer the query, each with its source URL.

Can Exa be used for proactive briefings and monitors?

Create an Exa Monitor with a search query, a schedule, and a webhook URL. On each run, Exa reruns the search, deduplicates against results it already sent, and posts new updates to your webhook as a text summary or as JSON in your pre-defined schema.

Is Exa a replacement for Bing or similar search APIs?

Yes. Microsoft retired the Bing Search APIs in August 2025. Exa does the same job for agents and applications that rely on search.

What about security and compliance?

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.
