🟢search_stations(query, federalState, locale)
Search stations in Germany and its neighbouring countries — river gauges, groundwater wells, reservoirs, coastal gauges — by name or water body, optionally filtered by region (a German federal state or a country code). latestValue is given in the station's unit.
