Basically, there is no such thing as an "Open Source API". APIs are not software, and we've already seen the damage that treating APIs as software (for copyright purposes) can do.
The proper abstraction for APIs (and protocols, and file-formats, etc.) is the standard, which ideally admits the possibility of multiple interoperable implementations, both proprietary and open source (patents being the joker in the deck, unfortunately).
