The Reverse WHOIS API searches our 3.6B+ record database backward. You provide an owner attribute and receive every domain connected to it. Four search dimensions are supported: email address, registrant name, company name, and domain keyword. Each accepts either exact-match or pattern-based queries depending on the identifier type.
Authorization
You can make authorized requests to our API by passing API key as a query parameter. To get your API key, login to our billing dashboard and get your API key! If your API key has been compromised, you can change it by clicking on reset button in billing dashboard.
