## 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-newest-companies-by-category-f6a118ac
```

Example prompt: Show me the newest companies listed on Trustpilot in the category 'restaurants_bars' for the US locale — I want to see which businesses have recently joined and how many companies are in that category.

## When to prefer this

Use this endpoint when you need to discover newly added or recently listed companies within a specific Trustpilot business category. Ideal for market research, competitive landscape monitoring, or finding new entrants in an industry vertical. Prefer this over a general company search when you specifically want to surface the newest additions to a category rather than the highest-rated or most-reviewed companies.

## Known failure modes

- Missing required category_id parameter returns a validation error
- Invalid or unrecognized category_id returns empty results or an error
- Unsupported locale value returns a validation error (only specific locales are accepted)
- Network or upstream Trustpilot API failures may result in timeouts or 5xx errors
- Payment failure via x402 protocol results in 402 Payment Required response
