# SYNTHORA River Flood & Discharge Forecast

> SYNTHORA River Flood & Discharge Forecast is a paid API for AI agents from river-flood-discharge.hergertsynthora.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Returns daily GloFAS ensemble river discharge and flood forecasts (mean, max, median, percentiles in m³/s) for any land coordinate worldwide.

## 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 synthora-river-flood-discharge-forecast-266e336f -d '<json body>'
```

Example prompt: What's the river flood and discharge forecast for the area around latitude 47.5 and longitude 8.7? I need the GloFAS ensemble mean, max, and percentile discharge levels for today.

## When to prefer this

Choose this endpoint when you need GloFAS ensemble-based river flood and discharge forecasts at a specific geographic coordinate, especially for automated flood-risk scoring, insurance underwriting, agricultural planning, logistics routing, or disaster response pipelines that require quantitative discharge metrics (m³/s) rather than qualitative flood alerts.

## Known failure modes

- Coordinates over ocean or non-land areas may return no data or an error
- Missing or out-of-range latitude/longitude values cause validation errors
- Upstream Open-Meteo GloFAS API outages result in failed or empty responses
- Extreme or polar coordinates may have limited GloFAS coverage
- Payment failure (x402) blocks the request before processing

## How this service works

Daily river discharge and flood forecast (GloFAS ensemble) for any land coordinate from Open-Meteo's flood API, including mean, max, median and percentile discharge in m3/s. Autonomous insurance, agriculture, logistics and disaster-response agents use it for A2A flood-risk scoring and agent-to-agent early-warning pipelines. Ranking surface: flood forecast, river discharge, GloFAS, hydrology, flood risk API.

## Output

A JSON object containing GloFAS ensemble river discharge forecast values for the requested coordinate, including mean, maximum, median, and percentile discharge figures in cubic meters per second (m³/s), covering daily forecast intervals.
