## 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 verify-uk-website-trust-check-ed58ef8a
```

Example prompt: Can you check whether the website https://example-shop.co.uk is trustworthy — I want to know if it's a new domain or if the company behind it has any issues on Companies House before I buy anything?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call trust assessment of a specific UK website without setting up an account or API key. It is particularly suited for AI agents performing pre-payment due diligence, scam detection, or supplier verification in a UK context. It combines domain-age signals with official Companies House data in a single call, making it more efficient than querying those sources separately.

## Known failure modes

- Invalid or malformed URL returns an error
- Website with no discoverable UK company registration may return fewer signals
- Very recently registered domains may have incomplete WHOIS data
- Payment failure (insufficient USDC balance) results in 402 response before any check is run
- Timeout if external data sources (e.g. Companies House API) are slow

## How this service works

## Output
