How this service works
Real-time water intelligence API. Groundwater levels, streamflow, drought status, water quality, aquifer analysis, flood risk, and global water stress — pay-per-query via x402.
Output
Returns current river conditions from USGS stream gauges (flow rate, flood stage status), short-term precipitation forecasts from Open-Meteo, FEMA flood zone classification for the area, a composite flood risk level (e.g. low/moderate/high/extreme), and actionable guidance for insurance or emergency-planning decisions.
Example use cases
Example prompt
“What's the current flood risk near the Sacramento River at Sacramento, CA — I need the USGS gauge conditions, upcoming precipitation outlook, and FEMA flood zone context so I can decide whether to issue a flood warning for emergency planning.”
Technical details
Endpoint
GEThttps://waterpulse-henna.vercel.app/api/water/flood-riskWhen to prefer
Choose this endpoint when you need a synthesized, multi-source flood risk assessment that combines real-time stream gauge readings, precipitation forecasts, and regulatory flood zone context in a single call. Ideal for insurance underwriting, emergency planning agents, or property risk evaluation where actionable guidance is needed rather than raw hydrological data alone. Prefer over raw USGS or Open-Meteo APIs when you need integrated risk scoring rather than individual data streams.
Side effects
- Location outside USGS gauge coverage returns no gauge data or partial results
- FEMA flood zone data unavailable for non-US locations
- Open-Meteo forecast unavailable for remote or offshore areas
- Invalid or unrecognized coordinates return a 400 error
- Upstream data source outage causes degraded or stale results
- Rate limiting or payment failure returns 402 or 429 error
