Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-halowerk-dns-intelligence-loopia-ns-articles-5d85f87d -d '<json body>'
```

Example prompt: Can you pull full domain intelligence for example.com — I need WHOIS info, DNS records, mail policy, TLS certificate details, and any subdomains you can find?

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call domain intelligence snapshot covering WHOIS, DNS, mail policy, TLS, and subdomains without signing up for an account or managing API keys. It is ideal for agents that need pay-as-you-go domain lookups billed in USDC, or for change-detection workflows where a baseline snapshot is compared against current state. Prefer it over general DNS resolvers when you need multi-dimensional domain data in one call.

## Known failure modes

- Invalid or malformed domain name returns a validation error
- Domain not found or unresolvable returns empty or error response
- Payment failure via x402 prevents the call from executing
- Rate limiting or upstream DNS/WHOIS service unavailability may cause timeouts
- Baseline schema mismatch (missing required fields) returns a 400-class error

## 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

A structured report containing WHOIS registration data, DNS records (A, MX, NS, TXT, etc.), mail policy details (SPF, DKIM, DMARC), TLS/SSL certificate information, and discovered subdomains for the queried domain. If a baseline is provided, the response may also include change detection relative to that snapshot.
