## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agents-openwebninja-com-trustpilot-companies-by-category-e7c06998
```

Example prompt: Show me the top-rated verified companies in the 'gaming' category on Trustpilot in the US, sorted by most reviews, with a minimum rating of 4 stars — give me the first page of results.

## When to prefer this

Use this endpoint when you need to discover or enumerate companies within a specific Trustpilot category with rich filtering (by country, city, rating, claimed/verified status). Prefer this over a general web search when you need structured, paginated company data tied directly to Trustpilot's taxonomy and review metrics.

## Known failure modes

- Invalid or unknown category_id returns an error or empty result
- Unsupported country code returns a validation error
- Page number beyond available results returns empty data set
- Invalid min_rating enum value causes a 400-level error
- Rate limiting or quota exhaustion returns a 402 or 429 response

## How this service works

Get the full list of companies in a specific company, with extensive filtering capabilities and pagination support.  Supports the options / filters available on the best companies in category page (e.g. https://www.trustpilot.com/categories/gaming).

## Output

Returns a JSON object containing category metadata (id, name, level, parent_id, company count), the total number of matching companies, a list of companies matching the filters, and request/pagination metadata including the page, locale, and category_id used.
