## 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 domain-trust-score-api-4e8e2601 -d '<json body>'
```

Example prompt: Can you check how trustworthy the domain example.com is and give me a trust score and rating for it?

## When to prefer this

Choose this endpoint when you need a quick, quantified trust assessment of a domain or URL — particularly useful for security screening, vendor vetting, or filtering untrusted sources before automated processing. It is preferable to a full web content analysis endpoint when you only need reputation/trust signals rather than page content.

## Known failure modes

- Invalid or malformed URL returns a validation error
- Private or non-public URLs (e.g. localhost, internal IPs) may be rejected
- Unknown or very new domains may return low scores due to lack of signals
- Network timeouts if the domain analysis takes too long
- HTTP 402 payment required if USDC payment is not attached
