DomainTools API Guide: Registrant Alert

The DomainTools API is organized into distinct products with queries that follow a REST-ful URL structure wherever possible. Each product offers free, un-authenticated access for the sample URLs listed with each product. If you haven't already, you may want to review the getting started document to learn about authentication and response formats.

The Registrant Alert API searches the ownership (Whois) records of domain names for specific search terms. The product is ideal for monitoring specific domain owners (such as "DomainTools LLC") to be alerted whenever their information appears in a newly-registred domain name. The API will also alert you to domains that no longer match a specific term.

NOTE: We are unable to provide a functioning test URL for this product because the data changes each day. See below for a sample response.

By default, the active data set is new or updated Whois records on the day you submit your API query. You should design your system to submit one API query per day for each registrant you want to monitor. If you experience a temporary failure in your processing routines, you can catch up on missing alerts up to six days back by providing the days_back parameter in your request.

For best results, schedule your daily update to occur no sooner than 3am Pacific time. This ensures the data has been fully processed and is ready for your use. If the data is not ready when you submit your query, you'll receive an error message and your account will not be charged.

Because each query consumes resources regardless of whether a match is found, your API account will be charged for each request you submit to the API even if no domain names match your query.
