Overview
Exa is an answer-engines product: a neural web search API built for AI applications that returns meaning-based results and full page content rather than keyword-matched links. It is run by Exa, a US company founded in 2021. You use it through its documented HTTP API and dashboard, plus the MCP server it publishes for AI toolchains. No material change was found in this review. Licence and regional coverage are not stated on the vendor pages checked in this review, so those points remain unconfirmed.
