Well, if you are looking at an API which’s license explicitly forbids copying, I would stay away from copying it.
While this case do give a precedent, it is much more about this specific case being a fair use according to the supreme court, than on whether APIs itself are copyrightable.
Also, given most programmers’ assumptions, I would not base much on that alone :D But IANAL, so do ask one, to be safe.
