Exa

Overview

Exa is infrastructure, not a destination. It gives developers a search endpoint designed to be called by an LLM or an agent: you can search by meaning rather than keywords, pull clean page contents and highlights instead of scraping HTML yourself, run deeper multi-step research calls, and set up monitors that watch the web for new matches. Pricing is pay-as-you-go per thousand requests, with cheap content extraction and a free monthly allowance to build against. If you are wiring a retrieval layer into an agent and have been fighting scrapers and rate limits, this removes a genuinely annoying class of work. The caveats are practical rather than philosophical. There is no consumer interface, so this is for people who write code. Costs are easy to underestimate because agents loop, and a chatty agent can burn a lot of requests before anyone notices. And semantic search is not always the right tool — for exact strings and known entities, a plain keyword index still wins.
