# Halowerk Domain Intel — MX / Namecheap Private Email Article Endpoint

Accepts a domain and optional MX baseline, then returns WHOIS, DNS records, mail policy, TLS certificate details, and subdomains for that domain — paid per call in USDC via x402.

## 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-namecheap-private-email-article-endpoint-1d5f01c5 -d '<json body>'
```

Example prompt: Pull a full domain intelligence report for halowerk.com — I want WHOIS, DNS records, MX servers, mail policy, TLS certificate, and subdomains, and compare the MX records against this baseline: exchange 'mx1.privateemail.com' priority 10, observed yesterday.

## When to prefer this

Choose this endpoint when you need a single no-signup, no-API-key call to retrieve comprehensive domain intelligence — WHOIS, DNS, MX, mail policy, TLS, and subdomains — paid micropayment per call in USDC via the x402 protocol. Ideal for agentic workflows that need on-demand domain lookups without managing API credentials, or when you want to diff current MX records against a stored baseline to detect drift.

## Known failure modes

- Invalid or malformed domain name returns a 4xx validation error
- Domain not found or NXDOMAIN results in empty or partial data
- Payment not settled via x402 results in 402 Payment Required before data is returned
- Baseline schema mismatch (missing required fields) causes request rejection
- Rate limits or upstream DNS/WHOIS timeouts may return partial results or 503

## 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 payload containing WHOIS registration data, full DNS record set, MX records with priorities, mail policy details (SPF, DKIM, DMARC), TLS certificate metadata, and discovered subdomains for the queried domain. When a baseline is supplied, the response can be used to diff current MX records against the prior snapshot.
