      description: |-
        Gets information about the owner of a given access token.

        Note that, as with the rest of the Client-Server API,
        Application Services may masquerade as users within their
        namespace by giving a `user_id` query parameter. In this
        situation, the server should verify that the given `user_id`
        is registered by the appservice, and return it in the response
        body.

                  of application services) then this field can be omitted.
