The Registrant Alert API searches new .com, .net, .org, .biz, .mobi and .us domain names for specific terms. If a newly registered or dropped(on-hold, deleted) domain name contains any of the search terms and does not contain any of the exclusion terms, then it will be returned in the search result. By default, the result contains all the domain names registered or dropped today(the day your query is submmited on). Your program can monitor each set of terms by submitting a single query each day(after 4AM PST). Optionally you can set since_date or days_back to backtrack the alerts up to 12 days back. The product is ideal for brand protection agents to monitor registrations that contain a trademarked word or product phrase.
