Anything or nothing. Nothing specific, though. (I can have a folder on my server named API, so a path on the server could be http://mysite.com/files/API/myAPIfile.hrml.)

It means that the base route for the APIs you access via URLs include “API” as part of the route.

If an API is present in a base URL, it typically means that the website offers an application programming interface. This allows developers to interact with the website in a more direct way, typically through code.
