x402
Domain Intel — WHOIS, DNS, TLS & Subdomain Lookup (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).
Given a domain name, returns aggregated intelligence including WHOIS data, DNS records (A, AAAA, MX, NS, TXT, CAA, SOA), mail policy (SPF/DKIM/DMARC), TLS certificate details, and discovered subdomains — paid per call in USDC via x402.

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 object containing: WHOIS registration data (registrar, registrant, dates), all major DNS record types (A, AAAA, MX, NS, TXT, CAA, SOA), mail authentication policy (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and a list of discovered subdomains.
Example use cases
Email deliverability audit for a domain
“Check the mail policy for mailchimp.com — I want to see the SPF, DKIM, and DMARC records along with any other DNS info relevant to email deliverability.”
TLS and subdomain recon for security review
“Run a full domain intel scan on acmecorp.io — I need the TLS certificate details and a list of discovered subdomains so I can assess our attack surface.”
WHOIS and nameserver lookup for due diligence
“Who owns the domain openai.com and what nameservers is it using? Give me the WHOIS data and full DNS records.”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-scaleway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive, all-in-one domain intelligence (WHOIS + DNS + mail policy + TLS + subdomains) in a single call, without requiring API key signup — especially when operating in an x402 micropayment context. Prefer this over individual DNS lookup tools when you need correlated multi-layer domain data. The optional baseline parameter allows diff-based monitoring against a previously observed DNS snapshot.
Side effects
- Invalid or malformed domain name returns validation error
- Domain not found or unregistered may return empty WHOIS and limited DNS results
- Payment failure via x402 results in HTTP 402 and no data returned
- TLS lookup may fail for domains without valid certificates
- Subdomain enumeration may return incomplete results for large or well-protected domains
- Rate limiting or upstream resolver timeouts may cause partial responses
