The Whois XML Domain Availability API allows users to check whether a domain name is available for registration. It has a coverage of 7.0+ billion WHOIS records and close to 600 million domains tracked across 2.864+ TLDs. Query results are available in both parsed fields and raw text in XML & JSON format. WHOIS data is updated in near real-time.
The following is a list of historical changes that were made to this asset. Typically, once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change. As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset, we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb. If you spot an error in our data and believe that a record needs to be updated in some way, the ProgrammableWeb team would very much like to hear from you at firstname.lastname@example.org
