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 object including WHOIS registration data, full DNS record set, mail policy records (SPF, DKIM, DMARC), TLS certificate metadata, and discovered subdomains for the queried domain. If a baseline snapshot is provided, it can be used for change-detection comparisons.
Example use cases
Phishing domain investigation
“I've got a suspicious domain — phishingsite-login.com — can you look it up and give me its WHOIS registration details, DNS records, TLS certificate info, and any subdomains? I want to know if it's newly registered and what infrastructure it's using.”
Email deliverability audit
“Check the mail policy configuration for mycompany.io — I need to see the SPF, DKIM, and DMARC records to make sure our email setup is correct.”
Competitor infrastructure recon
“Run a full domain intel report on competitor-brand.com — I want to see their nameservers, DNS records, subdomains, and TLS certificate details to understand their infrastructure.”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-mittwald?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, no-signup, pay-as-you-go call that bundles WHOIS, DNS, mail policy, TLS, and subdomain data together. It is ideal for agents doing one-off domain investigations, security triage, or infrastructure audits without committing to a subscription. Prefer it over dedicated WHOIS-only or DNS-only APIs when breadth of domain intelligence in a single round-trip matters and when paying in USDC via x402 is acceptable.
Side effects
- Domain not found or unresolvable — returns empty or error response
- Invalid domain format exceeding 253 characters — validation error
- WHOIS data unavailable for certain TLDs or privacy-protected registrations
- TLS certificate absent if domain has no HTTPS endpoint
- Subdomain enumeration may be incomplete depending on DNS zone exposure
- x402 payment failure if USDC balance is insufficient — request rejected before processing
