title: How to request the schema from a GraphQL service using curl?
body: <p>I have a curl script (as a standin for real code) that can POST to my company's GraphQL endoint and get data. It's working fine.</p>
  <p>It appears that it should also be possible to get the &quot;schema&quot; by crafting the appropriate request, but I have not found any way to do that at a HTTP level.</p>
  <p>If it is possible, what would the curl look like (the data)?</p>
  <p>Are there other requests other than &quot;query&quot; that I can use to gleen other information?</p>
