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 billions of 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 is the most precise and efficient Search API available today.

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 billions of 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 offers the fastest web search products on the market that are highly precise even at low latencies. API configurations can range from 200 milliseconds to 200 seconds, depending on the needs of your AI agent.

Exa Search is the highest quality search API at every latency, accepting natural language queries and returning token-efficient results with citations.

Exa Agent is a high-compute web agent that synthesizes information from across the web for the most complex deep research, list-building, and enrichment workflows.
