    More detailed request is available as raw.stop_by_name(), however returns dict instead of List[Stop].  

    ### Args:
        * access_id (`str`): Access ID for identifying the requesting client. Get your key on [RMV website](https://opendata.rmv.de/site/start.html).
        * query (`str`): Search for that token.
        * lang (`Literal[Language.DE, Language.DA, Language.EN, Language.ES, Language.FR, Language.HU, Language.IT, Language.NL, Language.NO, Language.PL, Language.SV, Language.TR]`, **optional**): The language of response. Defaults to `Language.EN`.
        * max_number (`int`, **optional**): Maximum number of returned stops. In range 1-1000. Defaults to `10`.
        * stop_type (`Literal[LocationType.A, LocationType.ALL, LocationType.AP, LocationType.P, LocationType.S, LocationType.SA, LocationType.SP]`, **optional**): Type filter for location types. Defaults to `LocationType.ALL`.
        * selection_mode (`Literal[SelectionMode.SLCT_A, SelectionMode.SLCT_N]`, **optional**): Selection mode for locations. `SelectionMode.SLCT_N`: Not selectable, `SelectionMode.SLCT_A`: Selectable. Defaults to `None`.
        * coord_lat (`Union[str, float]`, **optional**): Latitude of centre coordinate. Defaults to `None`.
        * coord_lon (`Union[str, float]`, **optional**): Longitude of centre coordinate. Defaults to `None`.
        * radius (`Union[int, float]`, **optional**): Search radius in meter around the given coordinate if any. Defaults to `1000`.
        * refine_id (`str`, **optional**): In case of an refinable location, this value takes the ID of the refinable one of a previous result. Defaults to `None`.
        * stations (`Union[str, list]`, **optional**): Filter for stations. Matches if the given value is prefix of any station in the itinerary. As a list or as a string separated by comma. Defaults to `None`.
        * filter_mode (`Literal[FilterMode.DIST_PERI, FilterMode.EXCL_PERI, FilterMode.SLCT_PERI]`, **optional**): Filter modes for nearby searches. Defaults to `FilterMode.DIST_PERI`.

    ### Returns:
        * dict: Output from RMV. Dict will contain "errorCode" and "errorText" if exception occurs.
