## 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 halowerk-domain-intel-mx-tencent-exmail-article-88b7460c -d '<json body>'
```

Example prompt: Pull the full domain intel for tencent.com — WHOIS, DNS, MX records, mail policy, TLS cert, and subdomains — and compare the MX records against my baseline where mx3.qq.com has priority 10 as observed on 2024-01-15.

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one domain intelligence snapshot — WHOIS, DNS, MX, SPF/DKIM/DMARC, TLS, and subdomains — in a single pay-per-call request with no API key or signup required. It is especially useful when you want to optionally diff current MX records against a stored baseline to detect mail infrastructure changes. Prefer it over separate WHOIS or DNS lookup tools when you need multiple record types at once, and when the x402 micropayment model (USDC, no subscription) fits your usage pattern.

## Known failure modes

- Invalid or malformed domain name returns a validation error
- Domain does not exist (NXDOMAIN) results in empty or error response
- Baseline schema mismatch (missing required fields like observed_at or records) causes a 400-level error
- Network timeout resolving DNS for obscure TLDs
- Payment failure via x402 prevents the call from completing
- Rate limiting or upstream DNS resolver errors

## 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 report including WHOIS registration data, DNS records, mail policy records (SPF, DKIM, DMARC), TLS certificate details, discovered subdomains, and current MX records. When a baseline is provided, the response includes a comparison highlighting changes in MX configuration since the observed baseline.
