RDAP Record Lookup

RDAP (Registration Data Access Protocol) is the standardized successor to the traditional WHOIS protocol. Developed by ICANN and the IETF, RDAP provides machine-readable JSON data, standardized error messages, and granular role-based authentication and privacy controls.

Unlike unstructured text WHOIS queries, RDAP guarantees standardized output schema across all generic and country-code top level domains.
