## 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 trustpilot-category-search-4d3d5b15
```

Example prompt: Search Trustpilot for companies in the 'software' category and show me the list of matching businesses, using en-US locale.

## When to prefer this

Use this endpoint when you need to discover or enumerate companies listed under a specific category or keyword on Trustpilot, especially as a first step before fetching individual company reviews. Prefer this over a direct company lookup when you don't know the exact Trustpilot company ID and need to search by topic or industry.

## Known failure modes

- Missing required 'query' parameter returns validation error
- Invalid locale enum value causes request rejection
- No matching companies found returns empty data array
- Rate limiting or payment failure returns 402 or 429 error
- Trustpilot upstream outage may cause 5xx errors
