To be clear, what is at stake is not using the API, it is to copy the API.<p>In the case of a website, let&#x27;s assume that you created ws.com, and that you developed an API that answered &#x27;A&#x27; when you call ws.com&#x2F;A, and &#x27;B&#x27; when you call ws.com&#x2F;B. Then you could sue anyone who&#x27;d develop a different website that <i></i>behaves<i></i> the same way even though the implementation itself may be completely different.
