## 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 x402-factory-flood-alerts-b8cac739
```

Example prompt: Are there any active flood warnings or watches right now near latitude 30.25, longitude -97.75 — and what's the model-based flood risk context for that area?

## When to prefer this

Use this endpoint when you need flood-specific alert data for a US location — it pre-filters NWS alerts to flood hazards so you don't have to sift through all severe weather alerts. Prefer it over a general severe-weather alerts endpoint when the user's concern is specifically flooding, flash floods, or water-related hazards. Ideal for real-time monitoring, travel safety checks, or property risk assessment at a specific coordinate or state level.

## Known failure modes

- Missing required lat/lon or state parameter returns a 400 error
- Coordinates outside the US (not covered by NWS) may return empty results or an error
- Invalid state code format (not 2 alpha characters) rejected by schema validation
- NWS data outage may result in stale or unavailable alert data
- Payment failure (x402) causes 402 response before data is returned

## How this service works

Active and forecast flood risk (NWS + model) — Active NWS alerts filtered to flood hazards for any US point, with model-based risk context. Same shape as /v1/alerts/severe with the hazard class fixed to flood.

## Output

A structured response containing active NWS flood alerts (watches, warnings, advisories) filtered to flood hazards for the queried US point or state, along with model-based flood risk context. Follows the same shape as the /v1/alerts/severe endpoint but scoped to flood hazard class only.
