How a call works
curl -s -X POST https://dns.halowerk.com/domain \
-H "Content-Type: application/json" \
-d '{"domain":"example.com","subdomains":true}'The first call answers with HTTP 402 and the accepted payment terms. An x402 capable client signs the terms and repeats the request; the answer arrives in the same round trip. Any x402 client library, or an MCP client pointed at /mcp, handles this without further setup.
What one answer contains
- WHOIS: registrar, creation, expiry, days remaining, status codes.
- DNS: A, AAAA, CNAME, MX, NS, TXT, CAA, SOA.
- Mail: SPF and DMARC with parsed policy, probed DKIM selectors, MTA-STS, provider.
- TLS: issuer, validity, chain, SAN list, trust result.
- Subdomains from Certificate Transparency.
- Nameserver operator and registrability.
Rules we follow
- Per TLD query budgets are respected; one lane per registry.
- A throttled registry yields
unknownfields with a reason, never a guess. - No invented fields. A silent DKIM selector is not reported as missing DKIM.
- Profiles cached 6 hours, WHOIS 24 hours.
- Public data only. No port scanning, no access control bypass.
