The API is ideal for Brand Protection Agents to monitor registrations that contain a trademarked word or product phrase, or which may contain minor variations to a firm’s brand.


  • 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.

  • 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 monitor for domain registration, expiration or ownership change. You have the option to exclude terms if they should not be a part of the search.

  • You can backtrack the alerts up to 14 days by setting sinceDate request parameter.

  • 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 can also use our "with typos" option, which adds automatically generated misspellings to your search terms to boost your anti-phishing activities.

Proactively track all the newly registered and recently expired domains specifically with our new Domain Research Suite Dashboard.
