## 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 x402helper-xyz-domain-trust-assessment-ab2e9f5f
```

Example prompt: Can you check whether example.com is OFAC-compliant and trustworthy before I send a payment to it?

## When to prefer this

Use this endpoint when an AI agent needs to perform compliance screening on a domain before initiating a payment or transaction, particularly when OFAC sanctions screening, trust scoring, and billing verification are all needed in a single call. Prefer this over general WHOIS or domain lookup services when the specific need is financial compliance and sanctions checking tied to a micropayment workflow.

## Known failure modes

- Missing required query parameter (domain, host, or url) — returns error response
- Domain not resolvable or malformed hostname — may return null result or error
- Payment not completed via x402 protocol — returns 402 Payment Required before delivering result
- OFAC service unavailable — may return failure or incomplete result
- Rate limiting or upstream compliance data unavailability

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a 'result' field containing the domain trust assessment outcome, including OFAC screening status, applicable rates, and billing verification details, plus a boolean 'success' flag indicating whether the lookup completed successfully.
