Until recently, when I would talk about “APIs”, I would qualify it by saying “Web APIs”, in order to distinguish from the older meaning of APIs as more the tightly-coupled APIs used in Java, C/C++, or even Visual Basic. If you just said “APIs”, until recently, some people may think you mean APIs like the Windows API (I can remember Charles Petzold’s excellent Windows API book was on my desk back when I was a programmer at an EDI VAN in the 90s).
