Returns the registry record of a registered domain name through the Registration Data Access Protocol: registrar, registration, expiry and last-change dates, status codes, nameservers and whether DNSSEC is on. It never returns the registrant’s name or contacts. Covers top-level domains whose registry is listed in the IANA RDAP directory with an https server; others answer rdap_available false.
Authentication
Requires x402 payment in thepayment-signature header.
Request Body

200.Notes
- Give the registered name itself, not a web address or a host under it: a host under a registered name (www.example.com) answers not found. Give an internationalized name in its
xn--form. foundfalse withrdap_availabletrue means the registry has no registration for that exact name.rdap_availablefalse means the tool could not ask: the IANA RDAP directory lists no registry server for the top-level domain, or lists one reachable over http only (the tool asks over https alone). It does not mean the name is free.- Status codes are in the registry’s words, for example
client transfer prohibited. - Dates are
YYYY-MM-DDUTC; a date the registry does not state is null. - The registry record carries no owner: the registrant’s name and contacts are never returned.
- Results return inline. The finished job stays available at
