Introduction¶
The Registration Data Access Protocol (RDAP) is built as a RESTful API using the benefits of HTTP(S).
The RDAP standard allows only two HTTP methods: HEAD and GET. More on usage of HTTP in RFC 7480.
Client authentication is not implemented, all data in responses is public.
IDNs are fully supported (both A-labels and U-labels, RFC 5890#section-2.3.2.1).
Registered RDAP servers can be found at https://data.iana.org/rdap/dns.json.
