> But features like URL discovery: I never understood why someone would do that. The custom media types are the key to this. Hypermedia API is like browsing a HTML website, but instead of HTML you use a custom markup language that drives your application's native views (or you can interpret it as sending commands to perform or options what the app can do next). So it's not a method of discovery how to use a networked database or invoke remote function calls, but a server-driven UI. That makes it extensible without client-side changes, because you can link more endpoints the same way you can add more pages to a website.
