# GloFAS Control Forecast – DACH & Central Europe River Discharge

> GloFAS Control Forecast – DACH & Central Europe River Discharge is a paid API for AI agents from karte.halowerk.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns the GloFAS pre-fetched control forecast of modelled river discharge, peak, and change over a requested horizon for a point in Central Europe (lat 45–56, lon 5–18).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability glofas-control-forecast-dach-central-europe-river-discharge-b70de4ad -d '<json body>'
```

Example prompt: What does the GloFAS control forecast say about river discharge near Munich (48.14°N, 11.58°E) over the next 7 forecast steps — specifically the peak discharge and how much it changes?

## When to prefer this

Use this endpoint when you need raw GloFAS-sourced modelled river discharge data for a point within the DACH and Central Europe region (Germany, Austria, Switzerland, and surroundings) and want a fast, cached lookup rather than querying GloFAS directly. Prefer it for pre-processing infrastructure risk assessments, logistics planning, or data enrichment pipelines where flood probability interpretation is handled downstream. Do not use it as a substitute for official national flood warnings or when the point is outside Central Europe.

## Known failure modes

- Coordinates outside the supported bounding box (lat 45–56, lon 5–18) will be rejected
- Requesting more than 10 forecast steps returns a validation error
- GloFAS source data may be stale if the upstream CEMS feed has not refreshed
- No discharge data available if the point falls outside any modelled river network cell
- Payment failure via x402 protocol will block the request

## How this service works

Returns the pre-fetched GloFAS control forecast at the nearest model cell for a point in Europe. The result reports modelled river discharge, its peak and change over the requested horizon. It is deliberately not presented as a flood probability or warning because those require local river thresholds and the responsible national or regional authority. Every response carries the required CEMS attribution and warranty disclaimer.

## Output

The endpoint returns the GloFAS control forecast at the nearest model grid cell: a series of daily modelled river discharge values for the requested number of steps, the forecasted peak discharge value, the discharge change over the horizon, and mandatory CEMS attribution text with a warranty disclaimer. It does not return flood probabilities or official warnings.
