# Chishiru Japan Satellite Vegetation Data API

> Chishiru Japan Satellite Vegetation Data API is a paid API for AI agents from api.chishiru.jp, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-11).

Returns satellite-derived vegetation indices and land cover data for a specified coordinate point in Japan

## Facts

- Endpoint: GET https://api.chishiru.jp/v1/satellite/vegetation?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-satellite-vegetation-data-api-7c33dce1
```

Example prompt: What's the satellite vegetation index at 35.6810N, 139.7670E in Japan — I want to know how green that area is according to the Chishiru land data API.

## When to prefer this

Choose this endpoint when you need satellite-derived vegetation or land cover data for a specific geographic point in Japan, especially when combining with other Chishiru modules (zoning, hazard, terrain) for comprehensive land analysis. Prefer this over general GIS APIs when you need Japan-specific government open data at pay-per-call pricing with no API key setup.

## Known failure modes

- Coordinates outside Japan return an error or empty module data
- Invalid or missing lat/lon parameters cause a 400-level error
- Payment via x402/USDC fails if wallet balance is insufficient
- Rate limiting or network issues may cause timeouts
- Coordinates in ocean or non-land areas may return no vegetation data

## 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 (coordinate+resolution key), a modules object with satellite vegetation data (such as NDVI or land cover classification) under a 'status: ok' field, and a payment receipt with an id and expiry timestamp. The vegetation module provides satellite-derived greenery metrics for the queried point in Japan.
