Open toolA disposable check tells you whether the inbox is throwaway. A public-provider check tells you whether it's personal or business. A forwarder check tells you whether it masks the real inbox. Domain age tells you how new the domain is, the spam flag whether it has a history of abuse, and MX whether it can receive mail at all. None of them is a verdict on its own; most signup flows read two or three together.
Use them ad-hoc here. In production, every one of these answers comes back in a single API response. See the API documentation.
