Would this be a better fit as part of an OPTIONS request?

OPTIONS /orders

  {
    "GET": {
      "description": "All the orders."
      "links": {
        "self": { "href": "/orders" },
        "next": { "href": "/orders?page=2" },
        "find": { "href": "/orders{?id}", "templated": true },
        "admin": [
          { "href": "/admins/2", "title": "Fred" },
          { "href": "/admins/5", "title": "Kate" }
        ]
      }
    }
  }
