## 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-climate-module-b908c55f
```

Example prompt: Can you look up the climate data for the location at latitude 35.6810, longitude 139.7670 in Japan using Chishiru's land data API?

## When to prefer this

Choose this endpoint when you need official Japanese government climate data for a precise geographic point in Japan without a subscription or API key — ideal for one-off lookups, agent-driven property analysis, or research pipelines where pay-per-call micro-payment via USDC on Base is preferred over flat-fee plans.

## Known failure modes

- Invalid or out-of-Japan coordinates return an error or empty module data
- Insufficient USDC balance or failed x402 payment results in a 402 Payment Required response
- Coordinates outside Japan's land boundary may return no data or a 404
- Network timeouts on the government data backend may cause delayed or failed responses
- Malformed query parameters (e.g. non-numeric lat/lon) return a 400 Bad Request

## 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 containing a land_id (encoded as lat_lon_resolution), a modules object with climate data under the 'climate' key (status and data fields), a receipt object with an ID and expiry timestamp, and api_version. The climate module data reflects official Japanese government open data for the queried coordinates.
