Exa

Exa is a search engine designed to be called by software, especially AI agents and apps that need fresh information from the web. Instead of a results page, you send a query to its API and get back a list of matching pages, with options to include the cleaned text of each page, highlights or summaries.

It supports searches by meaning as well as by keywords, so a query can describe the kind of page you want rather than exact words. It also offers ways to find pages similar to a given URL and to filter by domain or date.

When comparing it with other search APIs, test it on your own queries, look at how fresh results are for your topic, how page content is returned, rate limits and pricing at your volume, and the terms on storing and showing results to your users.
