Notes
The service is a real-time monitor, not an archive: it returns roughly thirty-one days of measurement however much history is requested — a query for a full year returns the same 3,046 points as a query for thirty days. Hydrionis therefore collects it under the accumulate update mode, which unions each run’s window with what is already held rather than treating the window as the whole record. Hydrionis holds approximately one rolling month of German measurement to begin with, and the archive deepens prospectively with each collection run. It does not hold decades of German history and does not imply that it does. Terms of use verified 25 August 2026: DL-DE→Zero-2.0, which permits commercial use, redistribution and derivative works with no attribution condition.
