Nearly every piece of data you'll find us using on the DomainTools site is available for your use, including Whois Lookup, Whois History, Reverse Whois, Domain Suggestions, and more.
Discover relationships among web sites, domain owners and IP addresses with Name Server Reports, Reverse IP lookups and Reverse Whois Reports.
Find domains to register or buy with Domain Suggestions and Domain Search APIs.
Monitor hundreds of thousands of new domain registrations each day for keywords or ownership profiles with the Trademark Alert and Registrant Alert APIs.
Click the "Track this API" button on any profile page and never miss an API update, new app, or breaking news for that API again.
There are no source code libraries or how-to links for DomainTools. If you know one why not add it?
Could not get this to work. It keeps complaining "Unauthorized access to API service"
