I really wish people would more clearly distinguish library APIs from RPC APIs exposed by corporations' servers. I have no desire to deal with another company but I would love an open-source library implementing the client side of MMS, or at least some readable documentation about how the hell it works.

Do you have example of potential alternative naming schemes?

I would refer to these as "services" and "libraries"; referring to either as an "API" is conflating a tool with its interface.
