title: Azure API Manager expose all to public, get rid of Ocp-Apim-Subscription-Key
body: <p>I have some REST API that is proxied over Azure API Management. For some reason I'd like make it available public for all requests. From developer point of view I would like to get rid of setting key in header (or request):</p>
  
  <pre><code>Ocp-Apim-Subscription-Key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
  </code></pre>
  
  <p>Is it ever possible?</p>
