How this service works
Deterministic DNS/RDAP/TLS domain intelligence for AI agents. x402 inline, no account.
Output
Returns structured RDAP data for the queried domain including: registrar name, registration (creation) date, domain age, expiration date, and current domain status (e.g. active, suspended, pending delete).
Example use cases
Fraud detection via domain age
“Can you check the RDAP registration details for the domain in this suspicious email link — paypa1-secure.com — I want to know when it was registered, how old it is, and whether it's active?”
Competitor domain expiry monitoring
“Look up when competitor-brand.com expires so I can find out if it's coming up for renewal soon and what its current registration status is.”
Due diligence before domain acquisition
“I'm considering buying thecoffeeroasters.com — can you pull up the RDAP info to tell me the registrar, registration date, domain age, and expiration date before I proceed?”
Technical details
Endpoint
GEThttps://domain-intelligence.nordman-tehau.workers.dev/rdap?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative domain registration metadata — registrar, dates, age, status — from the modern RDAP protocol rather than legacy WHOIS. Prefer it over DNS lookup endpoints (which return resource records, not registration data) when the goal is ownership, age, or expiration information rather than IP addresses or mail server records.
Side effects
- Domain not found or unregistered — RDAP returns empty or 404-equivalent response
- TLD not supported by RDAP — some ccTLDs may lack RDAP bootstrap entries
- Rate limiting or upstream RDAP registry timeout
- Invalid domain name format in request body
- Network error reaching the Cloudflare Worker or upstream RDAP server
