## 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 domain-intel-mx-one-com-article-lookup-via-x402-7312c63d -d '<json body>'
```

Example prompt: Pull a full domain intelligence report for stripe.com — I need WHOIS, DNS records, mail policy, TLS cert info, and any subdomains you can find, and compare the current MX records against this baseline: mx1.stripe.com at priority 10, observed yesterday.

## When to prefer this

Choose this endpoint when you need a no-signup, pay-per-call domain intelligence lookup that bundles WHOIS, DNS, mail policy, TLS, and subdomain data in a single call, especially when you also want to diff current MX records against a recorded baseline. Prefer it over dedicated WHOIS-only or DNS-only APIs when breadth of signal matters and you want frictionless USDC micropayment billing via x402 without API key management.

## Known failure modes

- Invalid or malformed domain name returns a validation error
- Domain not found or unregistered may return empty WHOIS or DNS data
- Baseline schema mismatch (missing required fields) causes a 400-class error
- Payment failure via x402 (insufficient funds or unsupported wallet) blocks the call
- Rate limiting or upstream DNS timeout may cause delayed or partial results

## How this service works

Domain in, WHOIS, DNS, mail policy, TLS certificate and subdomains out. Pay per call in USDC over x402. No signup, no API key.

## Output

Returns a comprehensive domain intelligence bundle including WHOIS registration data, DNS records, mail policy details (SPF, DKIM, DMARC), TLS certificate information, discovered subdomains, and optionally a diff of current MX records against the supplied baseline
