## 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-aeo-audit-endpoint-d13aceec
```

Example prompt: Can you audit the domain example.com to check if it passes OFAC screening and billing verification?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call OFAC compliance audit or billing verification on a specific URL or domain without setting up a full compliance infrastructure. Best suited for one-off checks on third-party sites where regulatory screening is required before transacting.

## Known failure modes

- Missing required 'input' parameter returns validation error
- No URL, host, or domain provided results in incomplete audit
- Invalid or unreachable domain may return empty or error result
- Payment failure (insufficient USDC) blocks access with 402 response
- Sanctioned or blocked domains may return restricted result

## How this service works

## Output

Returns a JSON object with a 'success' boolean and a 'result' object containing the audit outcome, which may include OFAC screening status, rates information, and billing verification details for the submitted URL, hostname, or domain.
