WhoisXML Reverse Whois API

The service provides a listing of web domains registered by a specified person. A search can target partial names or multiple names to identify the desired set of domains. Both current registrations and historical information are available.

API methods support submission of a domain search query specifying at least one registrant name, or part of a name, possibly including wildcard characters to control the accuracy of matches in search results. Methods support search for current or historical registrations or both. The API also supports registration of currently available domains discovered in its search results.
