Disposable Email Service Validator Free REST API
Fake signups, trial abuse, and throwaway accounts all share one thing: a temporary email address. Query this REST API with any domain and instantly find out whether it belongs to a disposable / temporary email service (think 10minutemail, mailinator, guerrillamail, and thousands more). The API currently recognizes over 4,000 disposable email domains, and that list grows every day.
Drop it into your signup form, trial provisioning flow, newsletter subscription, or fraud-prevention pipeline to stop throwaway accounts before they cost you a seat, a credit, or an email send. The docs couldn't be simpler: the API accepts one query parameter - domain - and returns JSON with a boolean, isTempEmail, denoting whether the queried domain belongs to a disposable email service. It also echoes back the domain queried.
For example: https://www.sevenj.com/rosterapi/v1/tempemailcheck?domain=fuadd.me, will return the following:
{
"isTempEmail": 1,
"domain": "fuadd.me"
}
Test it yourself:

https://www.sevenj.com/rosterapi/v1/tempemailcheck?domain=gmail.com
