The API interface complies with the behavior stated in the RDAP's RFCs:
This implementation conforms to the RDAP Operational Profile for gTLD Registries and Registrars version 1.0. You can query for Domains, Nameservers, and Entities (Registrar objects). Querying for Contact objects is not supported.
Queries can be done for an exact match when the resource is specified directly in the URL. For example, to query for domain names, point the RESTful client to:
/rdap/domain/example.com where example.com is the TLD to query.
Queries can also be done using the asterisk as the wildcard character to match zero or more trailing characters. For example, a domain search by name:
/rdap/domains?name=exam*.com will return results for the domain names exam.com, exams.com, example.com, etc.
The only content-type supported in our responses is
application/rdap+json. If an RDAP client sends the
Accept header in its request we will ignore it.
