## 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-cc63f2e7
```

Example prompt: Can you pull the full land data for the point at 35.6810°N, 139.7670°E in Japan — I need zoning, hazard zones, land price, and earthquake risk for that exact location.

## When to prefer this

Choose this endpoint when you need authoritative, government-sourced land data for any specific geographic point in Japan — especially for real estate due diligence, urban planning, construction risk assessment, or disaster preparedness. It is uniquely suited for Japan-specific queries combining multiple data layers (zoning, hazard, terrain, seismic) in a single call with no API key required, using pay-per-call USDC micropayments.

## Known failure modes

- Coordinates outside Japan return no data or error
- Invalid or missing latitude/longitude parameters cause a 400 error
- Payment failure via x402/USDC prevents data return
- Specific modules may return non-ok status if government data is unavailable for that location
- Rate limits or network timeouts on the government data backend

## 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

A JSON object containing a land_id (formatted as lat_lng_radius), a receipt with ID and expiry, and a modules object with results for each requested data category (e.g. zoning with use area, BCR %, FAR %, zone name in Japanese), plus status indicators per module.
