Brand Alert API searches across all recently registered & deleted domain names and returns result sets consisting of domain names that contain term(s) that are specified by you.


  • If a newly registered or dropped (on-hold, deleted) domain name contains any of the search terms, then it will be returned in the search result.
  • You can monitor for domain registration, expiration or ownership change.
  • The Brand Alert API searches new .com, .net, .org, .biz, .mobi, .us, .pro, .coop, .asia and thousands of gtlds and cctlds for your specified terms.
  • You have the option to exclude terms if they should not be a part of the search.
  • By default, the result contains all the domain names registered or dropped within the last day. Your program can actively monitor each set of terms by automatically submitting a single query each day.
  • You can backtrack the alerts up to 14 days by setting sinceDate request parameter.
