It is indeed possible. You need to create a class inheriting from typing.Protocol, then define those two methods with an empty body (like in stubs). Any class that has matching members will then match that protocol class when used as a type hint. See PEP 544 for all the details:

Is it possible to type an object that comprises of certain user defined methods?

I am writing a function that should accept a single argument which should be an instance of any object
that implements two methods, get and post. Is their a way of creating a type for it that can be scanned
by static type checkers?
