# Chishiru Japan Land Data API – Hazard Zones

> Chishiru Japan Land Data API – Hazard Zones is a paid API for AI agents from api.chishiru.jp, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).

Returns hazard zone classifications for a given GPS coordinate in Japan, sourced from government open data, covering flood risk, landslide risk, and other natural disaster designations.

## 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-hazard-zones-dc6c6ca2
```

Example prompt: I'm looking at a property in Tokyo at 35.6810°N, 139.7670°E — can you pull the government hazard zone data for that exact spot to see if it's in any flood or landslide risk areas?

## When to prefer this

Choose this endpoint when you need authoritative Japanese government hazard zone classifications (flood, landslide, disaster risk) for a precise GPS coordinate anywhere in Japan, paid per-call via USDC with no API key setup. Prefer it over general mapping APIs when you need Japan-specific regulatory hazard data sourced directly from government open data, especially for real estate due diligence, urban planning, or disaster risk assessment workflows.

## Known failure modes

- Coordinate outside Japan — endpoint only covers Japanese territory, returns error or empty result
- Malformed or missing lat/lon parameters — returns 400 bad request
- Payment not completed or USDC balance insufficient — x402 payment required before data is returned
- Location in Japan with no government hazard data on record — returns empty or null hazard module
- Rate limiting or network timeout — returns 5xx error

## 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 (encoded from the coordinate), a modules object with a 'hazard' key showing government-classified hazard zone data for the point (e.g. flood zones, landslide risk areas, disaster risk designations), a status field, API version, and a receipt object with a payment receipt ID and expiry for the x402 USDC micropayment.
