# Trustpilot Discovery API

> Public Trustpilot data: a company's record and reviews, category directories, free-text search, and the full company index.

- [List category companies](https://docs.toolzerhub.com/reference/trustpilot/discovery/get-trustpilot-category.md): Returns one page of a Trustpilot category directory: 20 companies with TrustScore, rating, review count, location and claim status, in Trustpilot's own ranking. Requires slug. data is null when Trustpilot has no page for that slug.
- [List company domains](https://docs.toolzerhub.com/reference/trustpilot/discovery/get-trustpilot-domains.md): Returns a window of Trustpilot's complete company index — all 874,063 keys, each the exact string /trustpilot/company takes as domain. Names only, no score or review count. Paginate with shard, offset and limit.
- [Search companies](https://docs.toolzerhub.com/reference/trustpilot/discovery/get-trustpilot-search.md): Free-text company search, 10 results per page with TrustScore, rating, location and contact details. Requires query. data is null only when Trustpilot serves no results page; a query matching nothing returns an empty results array.
