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 containing WHOIS registration data (registrar, dates, registrant), full DNS record set, MX records with priorities, mail policy records (SPF, DKIM, DMARC), TLS certificate metadata (issuer, validity, SANs), and a list of discovered subdomains.
Example use cases
Email security posture audit
“Check the mail policy setup for acmecorp.com — I need to see their MX records, SPF, DKIM, and DMARC configuration to assess their email security posture.”
Competitor domain reconnaissance
“Pull a full domain intel report on rivalstartup.io — I want WHOIS ownership info, DNS records, TLS certificate details, and a list of any subdomains.”
Phishing domain investigation
“Investigate suspiciousdomain.net for me — I want to see who registered it, what DNS records it has, whether it has valid TLS, and any subdomains that might be hosting malicious infrastructure.”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/mx-hornetsecurity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal domain intelligence snapshot in a single call — covering WHOIS, DNS, mail policy, TLS, and subdomains — without signing up for an account or managing API keys. Ideal for ad-hoc investigations, security research, or agent workflows that need to pay per-lookup in USDC via x402. Prefer this over dedicated WHOIS-only or DNS-only APIs when breadth of signal matters more than depth on a single record type.
Side effects
- Domain does not exist — empty or error response for unregistered domains
- WHOIS privacy protection — registrant details may be redacted
- Rate limiting or payment failure — x402 payment not accepted
- Invalid domain input — malformed domain string rejected
- TLS certificate absent — domain may not serve HTTPS
- Subdomain enumeration may be incomplete for large or well-protected domains
