API Description:
This API takes an internet domain as a parameter and returns a boolean indicating whether or not the domain hosts a free public email provider service. The API currently recognizes over 6,000 domains that host free email services, and that number grows every day.
This single-purpose API has any number of applications, such as checking to make sure only corporate emails - and not public emails - are allowed to sign up on a given registration flow, and/or blocking registrations from free email providers.
An example of use is passing "protonmail.com" as the domain, and the API will return 1, meaning there is a free email service hosted on that domain. Or if you pass "abccompany.com", it will return 0, meaning there is no free public email service hosted on such domain.
