title: Show REST documentation if Content-Type differs application/json
body: <p>Is it a good idea to show documentation of a particular REST resource if clients <code>Content-Type</code> is other than <code>application/json</code>? I mean, if a developer tries to fetch a REST resource URL in browser he gets something like <a href="https://developers.google.com/google-apps/calendar/v3/reference/acl/delete" rel="nofollow">this</a>.</p>
