Requests are made as strings using HTTP GET method. All outputs are provided as a JSON formatted response.
Authentication is needed in order to use the API, and for this a WhoAPI account is required. You'll need your API key every time you make a request. You have the option to limit API requests by a certain IP addresses in your account settings.
You can find your unique API key inside the "My account" section on the left once you register.
Example: In the professional package you can either make 8 whois queries per minute OR 50 queries on any other API. We don't measure the number of queries you make in a month.
