## 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 uk-flood-check-db7af99e
```

Example prompt: Can you check if there are any active flood warnings or alerts near the postcode OX4 2JY? I need to know the severity and which rivers or areas are affected.

## When to prefer this

Use this endpoint when you need real-time, live flood warning data for a specific English postcode sourced directly from the UK Environment Agency — ideal for property due diligence, insurance underwriting checks, logistics routing around flood events, or travel safety decisions. It is specifically for England and provides active published warnings rather than long-term flood risk ratings; do not use it for Scotland, Wales, or Northern Ireland, or when you need a static flood risk score rather than a current alert status.

## Known failure modes

- Invalid or non-English postcode returns an error or empty results
- Postcode outside England (Scotland, Wales, Northern Ireland) not supported — endpoint is England-only
- No active warnings returns empty arrays with a clear summary indicating no current alerts
- Environment Agency data feed temporarily unavailable may cause stale or failed responses
- Malformed postcode string (missing space, incorrect format) may cause lookup failure

## How this service works

Live flood warnings for an English postcode from the Environment Agency. Give a postcode; get any active severe flood warnings, flood warnings or flood alerts within 5 km (severity, area, river or sea, message, time raised) and the Environment Agency flood warning areas within 1 km, with a summary. Use for property checks, insurance, logistics and travel. England only. Reports published warnings; not a flood-risk rating.

## Output

A JSON object containing the queried postcode, a timestamp, an array of active flood warnings (each with severity, area name, river or sea name, message text, and time raised), an array of nearby Environment Agency flood warning areas within 1 km, the highest current severity level, and a plain-language summary of the flood situation.
