docs: Make a request to the given endpoint of the ``parking`` server.
  
          This returns the plain JSON (dict) response which can then be parsed
          using one of the implemented types.
  
          Args:
              endpoint (str): Endpoint to send the request to.
                  This string corresponds to the key in the ``ENDPOINTS`` dict.
              url_args (dict): Dictionary for URL string replacements.
              **kwargs: Request arguments.
  
          Returns:
              Obtained response (dict) or None if the endpoint was not found.
