get_forecast
Wasserstandsvorhersage
Newest published water-level forecast for a station: the median of the state agency model run, future points within the horizon. Only gauges whose state publishes numeric forecasts have one, so an empty result is normal. Indicative, not an official warning.

get_readings
Messreihe
Time series for a station (downsampled to ≤200 points; history depth on this tier: last 90 days, default last 7 days). type "level" (default) → level series as stored valueCentimeters: centimetres above gauge zero for most gauges, but an elevation ×100 for groundwater wells and for gauges reporting an absolute elevation (Swiss gauges, the Neusiedler See) — divide by valueDivisor to read it in unit. type "discharge" → discharge Q in m³/s where the station provides it.

search_stations
Pegel suchen
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.
