The Whois XML Reverse WHOIS API allows developers to find all domain names which contain a specified search term (i.e., name, email, address, phone, etc.) in their WHOIS records. Query results provide all the domain records that correspond to the search terms used and are made available in XML & JSON formats. With the API, it's possible to discover all domain names associated with an individual or an organization as well as find connections with other domains and their owners. Practical usages include cybersecurity, law enforcement, brand protection, marketing research, and cyber fraud prevention.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
