In layman’s terms: You know how sites like noobmeter and wotlabs know your various stats? Well, the API is what Wargaming provides to make those things available to those sites.

I meant to say something like #include math.h

These comments simply swallow the angled brackets that programmers normally use . . .

APIs are actually older than dirt in the programming world, and aren’t limited to web based applications. C headers are considered to be APIs. If you put an #include into a C file, you’re using something in the C standard library, which is an API available to all C programmers.

Web APIs are actually a newer development in the programming world compared to the generic concept of the API itself. The generic concept of the API can be traced back to the ’90s, if not older. The generic concept of the API has been our bread and butter for as long as I can remember, and everything you touch is very likely to use an API somewhere, even if it’s a non-web API.
