x402
Domain Intelligence - DNS/RDAP/TLS Lookup is a paid API for AI agents from domain-intelligence.nordman-tehau.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-11).
Returns deterministic DNS records, RDAP registrar data, and TLS certificate info for any domain name in a single call.

How this service works
Deterministic DNS/RDAP/TLS domain intelligence for AI agents. x402 inline, no account.
Output
A JSON object containing: DNS records (A, AAAA, MX, NS, TXT, CAA, CNAME, per-record errors, minimum TTL), TLS info (certificate count, subject CN, TLS version), RDAP registrar details and source URL, a confidence score (0–1), data age in seconds, whether the result was cached, and which sources (dns, rdap, tls) were queried. Also includes an ok flag and schema_version.
Example use cases
Verify domain before sending email campaign
“Before I send this marketing campaign, check the DNS MX records and TLS status for mailchimp-partner.com — I want to make sure it's a legit domain and not a lookalike.”
Security audit of competitor infrastructure
“Pull up the full DNS, RDAP registrar, and TLS certificate details for acme-corp.io — I need to understand their infrastructure setup.”
Check if newly purchased domain is propagated
“I just registered newstartup.dev — can you check its DNS A records, nameservers, and TLS certificate to see if everything has propagated correctly?”
Technical details
Endpoint
GEThttps://domain-intelligence.nordman-tehau.workers.dev/intelligence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call aggregation of DNS, RDAP, and TLS data for a domain without managing multiple separate lookups. It is ideal for agents doing domain verification, security audits, or infrastructure checks where paying $0.002 per call via x402 (no account required) is acceptable. Prefer this over raw DNS libraries when you also need registrar/RDAP and TLS cert metadata in one response.
Side effects
- Domain not found or does not exist — RDAP/DNS queries return errors per source
- TLS lookup fails if domain has no HTTPS endpoint — tls.ok will be false
- RDAP source unavailable for some TLDs — rdap.ok may be false
- Invalid domain format in query parameter returns error response
- Network timeout to upstream DNS/RDAP/TLS servers may cause partial results with per-source errors
