If you look at the output you receive from print() and also in your Traceback, you'll see the value you get back is not a string, it's a bytes object (prefixed by b):
b'{\n "note":"This file .....
If you fetch the URL using a tool such as curl -v, you will see that the content type is
Content-Type: application/json; charset=utf-8
So it's JSON, encoded as UTF-8, and Python is considering it a byte stream, not a simple string. In order to parse this, you need to convert it into a string first.
Change the last line of code to this:
info = json.loads(js.decode("utf-8"))
