  @doc """
  `parse_json/0` returns a list of maps containing statuses. e.g:

  ```elixir
  [
    %{
      id: "1",
      text: "verified",
      "desc": "A person verified by a 3rd party OAuth provider"
    },
    ...
  ]
  ```

  All statuses MUST have an `id` and `text` field.
  Ideally they should also have a `desc` (description),
  please help to expand/refine the description any status 
  that is not well defined but avoid changing the `text` or `id`.
