Weather Ensemble – Multi-Model Probabilistic Forecast
x402
Weather Ensemble – Multi-Model Probabilistic Forecast is a paid API for AI agents from ensemble.netzhandwerker.de, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).
Returns per-hour ensemble statistics (median, p15/p85 band, min/max, model count, agreement score, rain probability, frost assessment) plus DWD warnings for a geographic point, pooled across up to 12 NWP models.

How this service works
Twelve weather models compared hour by hour. Spread, agreement score, ensemble rain probability, frost and DWD warnings. Pay per call in USDC over x402.
Output
A JSON response with hourly arrays for each requested variable, including median, p15/p85 percentile band, min, max, spread, and model count per hour; an agreement score per hour; rain probability pooled from ensemble members; frost assessment flags; circular consensus for wind direction; majority-vote weather codes; and active DWD official warnings for the target point.
Example use cases
Outdoor event risk assessment
“I'm planning an outdoor festival in Hamburg on Saturday — can you get me a 48-hour ensemble forecast for lat 53.55, lon 9.99 and show me the rain probability and wind speed spread so I can gauge how risky the weather is?”
Vineyard frost monitoring alert
“Check the ensemble forecast for my vineyard at lat 49.78, lon 8.12 for the next 5 days and flag any hours where the frost assessment is concerning — I need the temperature band and model agreement score for each of those hours.”
Aviation route weather confidence check
“Give me a 24-hour ensemble forecast for lat 51.47, lon -0.46 using only the ECMWF IFS, GFS, and ICON EU models, and tell me how many models agree on cloud cover and wind gusts each hour — I need to know how confident we can be about the conditions.”
Technical details
Endpoint
POSThttps://ensemble.netzhandwerker.de/ensemble?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need uncertainty quantification rather than a single deterministic forecast — especially for high-stakes decisions (events, agriculture, aviation, logistics) where knowing the spread and inter-model disagreement matters. Prefer this over single-model weather APIs when you want rain probability derived from ensemble pooling, frost risk assessment, official DWD warnings, or want to know how many models support a given forecast hour. Best for locations in Europe where ICON and regional models add resolution, but global models are also included.
Side effects
- Invalid lat/lon outside valid ranges (-90 to 90, -180 to 180) returns validation error
- Fewer than 2 models selected returns error since single-model comparison is undefined
- Hours exceeding 168 rejected; short-range models (e.g. icon_d2) will have lower model counts beyond their native horizon
- Unknown timezone string causes parsing failure
- Requesting more than 8 variables simultaneously rejected
- Payment not sent or insufficient USDC triggers 402 response
- External NWP model API unavailability may reduce model count in results or cause timeout
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| lat | number | Latitude in decimal degrees. |
| lon | number | Longitude in decimal degrees. |
| hours | integer | Forecast hours, up to 168 (seven days). Short range models drop out beyond their own horizon; the per hour "models" count shows it. |
| models | array | Restrict the comparison to a subset of the twelve models. At least two, because a comparison of one model is just a forecast. |
| timezone | string | IANA zone name for the returned timestamps, for example Europe/Berlin. |
| variables | array | Which variables to compare. wind_direction_10m is aggregated as a circular mean with a directional consensus, weather_code as a majority vote; every other variable gets median, p15, p85, min, max and spread. |
