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.
Example use cases
Pre-purchase real estate due diligence
“I'm considering buying a property in Tokyo at 35.6810°N, 139.7670°E — can you get me the zoning classification, building coverage ratio, floor area ratio, and any hazard zone or flood risk info for that exact spot?”
Construction site risk assessment
“We're planning a building project at coordinates 34.6937°N, 135.5023°E in Osaka — look up the ground motion data, terrain info, and earthquake records for that location so we can assess structural risk.”
Disaster evacuation planning
“For the location at 35.3606°N, 138.7274°E near Mount Fuji, can you find the nearest evacuation sites and tell me what natural hazard zones that area falls under?”
Technical details
Endpoint
GEThttps://api.chishiru.jp/v1/land?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
