The Whois API returns well-parsed whois fields in XML and JSON formats. Use it to track domain registrations, check domain name availability, detect credit card fraud, locate users geographically. The service automatically follows the whois registry referral chains until it finds the correct whois registrars with the most complete whois data. Works over basic HTTP and avoices firewall-related problems of accessing Whois servers on port 43.
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,
