## 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-domain-trust-881c1775
```

Example prompt: Before making any calls to stripe.com, check if that domain is trustworthy — give me a trust assessment so I know whether it's safe to proceed.

## When to prefer this

Use this endpoint when an AI agent needs a quick, pay-per-call trust signal about an unknown domain before interacting with it, especially in agentic pipelines where safety gates are needed. Prefer this over manual WHOIS lookups or reputation databases when you need a single structured trust score optimized for agent consumption and are already operating in an x402/Base mainnet payment context.

## Known failure modes

- Payment not provided or incorrect — endpoint returns 402 Payment Required
- Invalid or malformed domain string — endpoint may return an error or low-confidence result
- Domain not recognized or too new to have reputation data — may return low trust score with low confidence
- Network timeout or worker unavailability — returns 5xx error

## How this service works
