Developers building agents that need live web results get a monthly free allowance, then $4 per 1,000 searches, which adds up at volume.

Kenning's take

What it does

Exa runs its own web index and sells search to developers through an API, so AI apps and agents can look things up on the live web. Endpoints cover fast search, full page contents, deep multi-step search, scheduled monitors and an asynchronous research agent. It also offers an MCP server and connectors for Claude and ChatGPT.

• Search API with 180ms to 1s latency options
• Contents API for full page text
• Deep Search with cited answers
• Monitors for scheduled searches
• People, company and research paper indexes
• MCP server

Who it suits. Developers building AI assistants, coding agents and research tools that need live web data.
