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-email-domain-enrich-fe767fae
```

Example prompt: Can you check if the email domain for payments@acmecorp.com is OFAC-compliant and pull any billing verification or rate info associated with it?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call OFAC screening or email domain enrichment check without committing to a full KYC vendor contract. At $0.006 USDC per call via x402, it suits AI agents needing on-demand compliance checks before processing payments or onboarding counterparties.
