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, registrant, dates), full DNS record set (A, MX, NS, TXT, etc.), mail policy evaluation (SPF, DKIM, DMARC), TLS certificate details (issuer, validity, SANs), and a list of discovered subdomains for the queried domain.
Example use cases
Security audit of suspicious domain
“I received an email from support@paypa1-secure.com and I want to know if this domain is legit — can you look up its WHOIS ownership, DNS records, mail policy, and TLS certificate so I can tell if it's a phishing domain?”
Monitor competitor infrastructure changes
“Check the full DNS and subdomain profile for competitor.com and compare it against the baseline I observed last week — I want to see if anything has changed in their infrastructure.”
Email deliverability configuration check
“Can you audit the mail security setup for mybusiness.io? I need to see if SPF, DKIM, and DMARC are properly configured, along with the current DNS records.”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-variomedia?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal domain intelligence report in a single call without API key registration — ideal for ad-hoc security investigations, one-off domain audits, or agentic workflows requiring pay-as-you-go access. Prefer it over traditional WHOIS-only tools when you also need DNS, TLS, and mail policy data in one response.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain does not exist (NXDOMAIN) may return empty or partial results
- Payment failure via x402 prevents the call from executing
- Rate limiting or upstream DNS/WHOIS provider outages may cause timeouts
- Private WHOIS registrations return redacted registrant details
- TLS data unavailable for domains not serving HTTPS
