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
A structured report containing: WHOIS registration details (registrar, registrant, creation/expiry dates), full DNS record set (A, MX, NS, TXT, CNAME etc.), mail security policy evaluation (SPF, DKIM, DMARC), TLS/SSL certificate metadata (issuer, validity, SANs), and a list of discovered subdomains.
Example use cases
Security audit of vendor domain
“I need to vet a new vendor before onboarding them — can you pull the full domain intel on acmecorp.io? I want to see who registered it, when it expires, their mail security setup like SPF and DMARC, their TLS cert, and any subdomains you can find.”
Monitoring DNS changes over time
“I took a baseline snapshot of example.com's DNS records last week — here it is. Can you run a new domain intel lookup on example.com and compare it against my baseline to see if anything has changed?”
Investigating a suspicious email sender domain
“I got an email from someone at payments-verify-us.com and I'm not sure if it's legit. Can you pull the domain intelligence on payments-verify-us.com so I can see the WHOIS ownership, mail policy records, and TLS certificate details?”
Technical details
Endpoint
POSThttps://dns.halowerk.com/domain/articles/ns-godaddy?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-faceted domain intelligence report in a single call without API key registration — especially suitable for AI agents that need pay-as-you-go access via x402/USDC micropayments. Prefer this over separate DNS, WHOIS, and certificate tools when you want consolidated output covering DNS, mail policy, TLS, and subdomains simultaneously at sub-cent cost per query.
Side effects
- Invalid or malformed domain name returns validation error
- Domain does not exist or is not registered — may return empty WHOIS or NXDOMAIN
- Payment failure via x402 results in 402 response with no data returned
- Timeout on DNS or WHOIS lookups for slow registrars
- Rate limiting or blocking by upstream WHOIS providers for certain TLDs
- Subdomain enumeration may be incomplete for large or well-shielded domains
