# Domain Intel MX Titan — Mail Policy & DNS Intelligence via x402

> Domain Intel MX Titan — Mail Policy & DNS Intelligence via x402 is a paid API for AI agents from dns.halowerk.com, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-13).

Accepts a domain name and optional MX baseline, returning WHOIS, DNS records, mail policy (SPF/DKIM/DMARC), TLS certificate details, and subdomain data — 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 domain-intel-mx-titan-mail-policy-dns-intelligence-via-x402-70360e96 -d '<json body>'
```

Example prompt: Can you do a full domain intelligence check on stripe.com — pull its WHOIS, DNS records, MX configuration, mail policy, TLS cert, and any subdomains you find? Compare the MX records against this baseline: [{"exchange":"mail.stripe.com","priority":10}] observed on 2024-01-15T00:00:00Z.

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call domain intelligence report covering WHOIS, DNS, mail policy, TLS, and subdomains together — especially when you want to avoid signup or API key management and can pay micro-amounts in USDC via x402. Prefer it over raw DNS resolvers when you need mail security posture (SPF/DKIM/DMARC) and TLS cert data in the same response, or when you want MX baseline comparison built in.

## Known failure modes

- Invalid or malformed domain name returns a validation error
- Domain not found in WHOIS returns empty or partial WHOIS data
- DNS resolution timeout for unresponsive nameservers
- Baseline schema mismatch (missing required fields: domain, observed_at, records) causes request rejection
- Payment failure via x402 results in 402 response before any data is returned
- Rate or quota limits may apply per payment wallet address

## 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 structured report for the queried domain including: WHOIS registration data, resolved DNS records (A, AAAA, MX, NS, TXT, CAA, SOA), mail policy details (SPF, DKIM, DMARC), TLS certificate information, enumerated subdomains, and — when a baseline is supplied — a diff highlighting changes in MX configuration since the observed timestamp.
