Given an id as input argument, returns a JSON export of the resource’s menu structure.

The JSON returned is a nested list of objects which each contain the pages id, url and, optionally, any children:

[
  {
      "id": 51253,
      "title": "About",
      "url": "/about"
      "children": [
          {
              "id": 51246,
              "title": "Our team",
              "url": "/about/team"
          },
          {
              "id": 51246,
              "title": "Our work ethics",
              "url": "/about/ethics"
          }
      ]
  },
  {
      "id": 51254,
      "title": "Contact",
      "url": "/contact"
  },
  {
