Web search, built for enterprise agentsThe highest quality search API at every latency

An enterprise web search API is a service that lets a company's own software query the live web programmatically, rather than through a browser.

Exa is a web search API built for that use. It accepts a natural-language query, searches a continuously refreshed index of 100 billion pages, and returns the relevant passages with a source URL for each one, in a format an AI agent or application can consume directly.

Exa returns the most relevant passages, not just links, so agents spend fewer tokens per answer.

Unlike traditional keyword-based search engines, Exa performs best when you prompt it like you would prompt an LLM. Exa retrieves relevant pages by meaning, so a query written in plain language returns pages that match what you meant, including ones that never use your terms.

Results come back as token-efficient excerpts with citations. That is what makes Exa a fit for AI agents, where context is limited and every token has a cost.

Exa tracks, indexes, crawls, and monitors over 100 billion webpages that are made available via the Exa API. Additionally, Exa partners with quality data providers to source information that is not available on the public web.

Many of Exa's data partners can be accessed via the Exa Connect program.

Exa Search returns results in about 250 ms with the instant search type. Slower search types trade speed for depth: fast takes about 450 ms, auto about 1 second, and the deep types 4 to 40 seconds, while Exa Agent runs longer research asynchronously. Teams pick the type that most closely resembles their request.
