# Domain Intel — Halowerk DNS Intelligence API

> Domain Intel — Halowerk DNS Intelligence API 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).

Given a domain name, returns WHOIS, DNS records (A, AAAA, MX, NS, TXT, CAA, SOA), mail policy (SPF/DKIM/DMARC), TLS certificate details, and subdomains, 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-halowerk-dns-intelligence-api-3034fecb -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need a single-call, comprehensive domain intelligence bundle (WHOIS + DNS + mail policy + TLS + subdomains) without signing up for an account or managing API keys. Ideal for ad-hoc domain audits, security investigations, or automated enrichment pipelines that pay per query in USDC. Prefer it over dedicated DNS resolvers when you need the full cross-section of domain metadata in one request.

## Known failure modes

- Invalid or non-existent domain name — returns error with no records
- WHOIS data unavailable for certain TLDs — partial response without WHOIS
- Payment not completed via x402 — 402 Payment Required response before data is returned
- Rate limiting or temporary upstream DNS resolver failures
- Domain input exceeds 253 character limit — validation error
- TLS certificate unavailable for domains without HTTPS — partial response

## 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 registry data (registrant, registrar, expiry), DNS records (A, AAAA, MX, NS, TXT, CAA, SOA), mail policy analysis (SPF, DKIM, DMARC), TLS/SSL certificate details, and discovered subdomains.
