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 (encoding the coordinates and resolution), ground motion data under the modules.ground_motion key, and a receipt with an ID and expiry timestamp confirming the paid x402 call. The ground motion module includes seismic risk metrics sourced from Japanese government datasets.
Example use cases
Real estate seismic due diligence
“I'm looking at buying a property in Shinjuku, Tokyo at coordinates 35.6938, 139.7034 — can you check the seismic ground motion risk for that exact spot using Japanese government data?”
Construction site hazard assessment
“We're planning to build a factory at lat 34.6937, lon 135.5022 in Osaka. Can you pull the ground motion hazard data for that location so we can assess earthquake risk before breaking ground?”
Insurance risk underwriting for Japan property
“I need to underwrite a property policy for a site at latitude 35.1815, longitude 136.9066 in Nagoya — get me the ground motion risk data from the Japanese government land records.”
Technical details
Endpoint
GEThttps://api.chishiru.jp/v1/land/ground_motion?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, government-sourced seismic ground motion data for a specific geographic point in Japan, especially for real estate due diligence, construction planning, insurance underwriting, or disaster risk assessment. It is pay-per-call with no API key required, making it ideal for low-volume or on-demand lookups. Prefer this over general earthquake databases when you need point-level precision tied to Japanese government hazard maps.
Side effects
- Coordinates outside Japan bounds — returns error or empty module data
- Invalid latitude/longitude format — returns 400 bad request
- Payment failure via x402/USDC — returns 402 Payment Required
- Temporary unavailability of upstream government data source — module status may indicate error
- Rate limiting or network timeout — returns 5xx error
