GP is asking for examples of when copyrighting an API would be a problem.  They used web APIs because that&#x27;s apparently what they are most easily able to call to mind.<p>I&#x27;ve found many programmers think of APIs as ways of interacting with remote systems, usually via http&#x2F;json&#x2F;REST.  Personally, I think of an API as things like an argument signature in a library, or even hooks in an OS.<p>To me, API literally means a programmatic interface to some code.  How you write code to interact with other code.<p>[Not that you said anything differently, I was just trying to expand a little on the different perspectives of &#x27;API&#x27; I have encountered.]
