About PureSignup

PureSignup is a hosted API that checks whether an email address or domain belongs to a disposable email service. One call with Bearer token authentication returns a risk level and the sources that flagged the domain, so a signup form can reject throwaway addresses and keep user data clean.

The site states that its database covers more than 160,000 disposable domains, is monitored for new ones daily and responds in under 80 ms using indexed lookups. Documentation includes curl examples and SDKs, and a try-it box tests any email or domain. A 7-day free trial is offered.
