How this service works
Registrar, creation and expiry dates, status codes and name servers of a domain from the registry's RDAP record, and whether the name looks available.
Output
Returns the domain's RDAP record including: registrar name, creation date, expiry/expiration date, last updated date, ICANN status codes (e.g. clientTransferProhibited), name servers, and a boolean or signal indicating whether the domain appears to be available for registration.
Example use cases
Domain availability pre-purchase check
“Is shopify.io available to register? Check the RDAP record and tell me if it's taken, and if so who registered it and when it expires.”
Brand protection monitoring
“Look up the WHOIS record for nike.net — I need to know the registrar, registration status, and expiry date to see if it's owned by Nike or someone else.”
Due diligence on acquired domain
“I'm about to buy the domain cryptovault.com — can you pull its RDAP record and tell me the creation date, expiry, registrar, name servers, and status codes?”
Technical details
Endpoint
GEThttps://api.cra-agent.tech/v1/paid/domains/whois?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable RDAP data about a domain — including registrar, dates, status codes, name servers, and availability — rather than raw WHOIS text parsing. Prefer it over manual WHOIS tools when building agents that need to programmatically check domain registration status or perform domain due diligence at scale.
Side effects
- Domain not found in RDAP (unregistered or TLD not supported) — may return empty or availability=true
- Invalid domain format supplied — 400 Bad Request
- TLD not covered by RDAP protocol — partial or no data returned
- RDAP upstream registry timeout — 502 or 504 error
- Rate limit exceeded — 429 Too Many Requests
