## 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-breach-lookup-endpoint-45d68b7a
```

Example prompt: Can you run an OFAC compliance screen on the domain example.com and tell me if it's sanctioned, along with any billing verification status?

## When to prefer this

Use this endpoint when you need a quick per-domain compliance lookup combining OFAC screening, exchange rate data, and billing verification in a single call, and your agent supports x402 USDC micropayments. Prefer this over manual sanctions databases when automating onboarding or partner verification workflows.

## Known failure modes

- Missing required domain/host/url query parameter returns an error
- Domain not found in screening database returns empty or null result
- Payment not completed (x402 flow incomplete) blocks access to response
- Malformed domain input may return a validation error
- Sanctioned domain may return a positive OFAC flag rather than data

## 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 'success' boolean and a 'result' object containing OFAC screening status, exchange rate data, and billing verification information for the queried domain.
