How this service works
Daily river discharge forecast from the Copernicus GloFAS model (5 km grid) served via Open-Meteo Flood API, data CC-BY 4.0. Query: ?latitude=45.75&longitude=4.85&forecast_days=7 (1-210 days; daily=river_discharge,river_discharge_max for extra variables). Returns ISO date + m3/s arrays -- flood risk, inland shipping (Rhine/Danube) and hydropower planning. 6h cache.
Output
A JSON object with a daily time series of river discharge values in m³/s (and optionally max discharge) for the requested coordinates and forecast horizon, along with the data source attribution (GloFAS/Copernicus via Open-Meteo, CC-BY 4.0), resolved latitude/longitude, and unit metadata.
Example use cases
Flood risk monitoring for municipalities
“Can you check the river discharge forecast for the next 14 days at our city coordinates? I need to know if we should activate emergency protocols based on expected water flow volumes.”
Inland shipping route planning
“What's the expected discharge forecast for the Rhine at our usual crossing point over the next 10 days? We need to know if water levels will support our barge operations.”
Hydropower plant operations
“Give me the daily river discharge forecast for the next 30 days at our dam location, including peak discharge values. We use this to optimize power generation scheduling.”
Technical details
Endpoint
GEThttps://data.greeneris.io/v1/hydro/riverWhen to prefer
Use this endpoint when you need authoritative, forecast-horizon hydrological data (river discharge in m³/s) sourced from the official GloFAS/Copernicus dataset for any geographic point on Earth. Prefer this over generic weather APIs when the specific need is river flow volume rather than precipitation or temperature. Ideal for flood risk assessment, infrastructure planning near waterways, or environmental monitoring workflows. The pay-per-call x402 model means no subscription is required.
Side effects
- HTTP 402 returned if payment not yet made — endpoint returns a machine-readable USDC price quote for retry via x402 protocol
- Invalid or out-of-range latitude/longitude returns an error (must be -90..90 and -180..180)
- forecast_days exceeding 210 returns a validation error
- No river data available at the given coordinates (e.g. open ocean or remote land with no modeled river) may return empty or zero discharge values
- Invalid daily variable name returns an error
