## 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 agent-trust-registry-1467e7a5 -d '<json body>'
```

Example prompt: Can you run a live trust verification on https://my-agent-service.example and get me the trust score, report, and badge URL so I can display it publicly?

## When to prefer this

Use this endpoint when you need an independent, live, third-party trust signal for an autonomous agent service — especially before integrating with or listing an unknown agent. Prefer it over self-reported credentials or static whitelists when you want a scored, badgeable, publicly verifiable result.

## Known failure modes

- Invalid or unreachable origin URL returns an error or low score
- Malformed URI input causes validation error
- Service unavailable if the registry's worker is down
- Origin domain that blocks verification crawls may return inconclusive report
- Payment failure (x402 protocol) blocks the call entirely

## How this service works

## Output

Returns a JSON object containing a numeric trust score (0–100), the verified origin URL, a boolean verified flag, a detailed report object with underlying checks, and a badgeUrl pointing to an embeddable public badge image.
