## 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 chishiru-japan-land-data-api-c0d187bf
```

Example prompt: Can you pull up the land data for the coordinates 35.6810, 139.7670 in Japan — I want to know the zoning type, building coverage ratio, floor-area ratio, and whether it's in any hazard zones?

## When to prefer this

Choose this endpoint when you need authoritative, government-sourced land data for any point in Japan — especially for real estate due diligence, urban planning, disaster risk assessment, or property development research. It is uniquely suited for Japan-specific regulatory and hazard data (zoning, BCR, FAR, flood/earthquake/landslide zones) that is not available from generic geocoding or mapping APIs. Prefer this over general geospatial APIs when you need Japanese regulatory compliance data or disaster risk profiles tied to a precise coordinate.

## Known failure modes

- Coordinates outside Japan return no data or an error
- Unsupported or malformed lat/lng values result in a 400-level error
- Payment failure via x402/USDC results in an authorization error before data is returned
- Specific data modules may return a non-'ok' status if government data is unavailable for that location
- Rate limiting or network errors may result in timeouts

## How this service works

Pay-per-call land data for any point in Japan from government open data: zoning, hazard zones, land prices, evacuation sites, earthquake records, climate, terrain, ground motion. x402 (USDC on Base), no API key.

## Output

Returns a JSON object keyed by the requested land coordinate, containing a 'modules' object with one or more sub-objects (e.g. zoning, hazard zones, land prices, evacuation sites, earthquake records, climate, terrain, ground motion), each with a 'status' field and a 'data' object containing the relevant government data fields. Also includes a payment receipt with an ID and expiry timestamp.
