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 (encoding the coordinates and grid resolution), a modules object with earthquake history data for the queried point, an api_version, service name, and a receipt with a unique receipt ID and expiry timestamp confirming the micropayment was processed.
Example use cases
Real estate due diligence in Tokyo
“I'm looking at buying an apartment in Shibuya — coordinates 35.6580, 139.7016 — can you check what earthquakes have historically hit that area using Japanese government data?”
Construction site seismic risk check
“We're planning a building project at 34.6937, 135.5023 in Osaka — can you fetch the historical earthquake records for that exact point so we can assess the seismic risk?”
Insurance underwriting for Japanese property
“I need the earthquake history for a commercial property in Sendai at coordinates 38.2688, 140.8721 to help price a natural disaster insurance policy.”
Technical details
Endpoint
GEThttps://api.chishiru.jp/v1/land/quake_history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need historical earthquake data specifically tied to a precise geographic point in Japan, sourced from authoritative Japanese government open data, with no API key required and pay-per-call USDC micropayment billing. It is ideal for real estate analysis, construction risk assessment, or insurance underwriting workflows where per-query cost efficiency matters and you need official seismic history rather than real-time alerts.
Side effects
- Coordinates outside Japan return no data or an error
- Invalid or malformed latitude/longitude causes a 400 error
- Payment failure via x402/USDC results in an unpaid/unauthorized response
- Rate limits or network timeouts may produce 5xx errors
- Coordinates in ocean or unpopulated areas may return empty earthquake records
