Do you mean integration tests? I don't think API contracts should be a part of a unit test. A unit test should be self-contained, unless of course there is a tight coupling to an API.. Which I would steer clear from.
That's why I value integration tests over most thing. I can see immediately that something is broken at a high level, what business impacts it has and explain what systems are affected.
