> Domain Intel by Halowerk is a paid API for AI agents from dns.halowerk.com, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-12).

Returns comprehensive domain intelligence including WHOIS, DNS records, mail policy (SPF/DKIM/DMARC), TLS certificate info, and subdomains for a given domain name, 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-by-halowerk-60751cf6 -d '<json body>'
```

Example prompt: Pull up everything you can on stripe.com — WHOIS, DNS records, mail policy, TLS cert details, and any subdomains you can find.

## When to prefer this

Choose this endpoint when you need a single, pay-per-call call that aggregates WHOIS, DNS, mail policy, TLS, and subdomain data in one shot without requiring an API key or subscription. It is ideal for ad-hoc domain investigations, security audits, or enriching a pipeline with domain metadata using micro-payments. Prefer alternatives if you need bulk batch lookups, very high-frequency polling, or need guaranteed SLA uptime.

## Known failure modes

- Invalid or malformed domain name returns validation error
- Domain does not exist (NXDOMAIN) may return empty or partial results
- Payment failure via x402 if insufficient USDC balance
- Rate limiting or temporary unavailability of upstream DNS/WHOIS resolvers
- Some WHOIS data may be redacted due to GDPR or privacy proxies
- TLS or subdomain enumeration may be incomplete for heavily firewalled domains

## How this service works

Requires an unauthenticated caller-owned baseline; returns real current NS/MX records, added/removed sets and tri-state target-provider transition. Current DNS comes from one bounded native recursive-resolver query; existing Dossier provides context. Resolver caching may apply; no account ownership or global migration-completion claim. Existing provider patterns are reused without new invented attribution. At most50records,domain253chars,9sbudget; DNSsubquery2s/oneattempt. Unknown provider remai

## Output

Returns a structured response containing: WHOIS registration data (registrar, dates, registrant), DNS records (A, AAAA, MX, NS, TXT, CNAME, etc.), mail policy records (SPF, DKIM, DMARC), TLS/SSL certificate details (issuer, validity, SANs), and a list of discovered subdomains.
