How this service works
Historical daily record of Japan earthquake counts and maximum magnitude, collected by this API since July 2026 from JMA data. Date-indexed series for seismic activity trend analysis, risk modeling, insurance and research agents.
Output
A date-indexed time series of daily records, each containing the date, the total number of earthquakes recorded in Japan that day, and the maximum magnitude observed — covering up to 400 days of history from the JMA-sourced dataset.
Example use cases
Example prompt
“Can you pull the Japan earthquake history for the last 60 days — I want to see the daily quake counts and peak magnitudes from JMA data so I can spot any recent seismic trends?”
Technical details
Endpoint
GEThttps://jp-data-api-production.up.railway.app/history/quakeWhen to prefer
Use this endpoint when you need structured, date-indexed historical seismic activity data for Japan specifically — particularly for trend analysis, risk modeling, insurance underwriting, or academic research. Prefer this over real-time earthquake alert APIs when you need aggregated daily summaries rather than live event streams, and when JMA-sourced authority matters.
Side effects
- days parameter exceeds 400 — API may return an error or cap the result
- days not provided — defaults to 30 days
- No data available before July 2026 — queries implicitly bounded by collection start date
- Payment failure (x402) — request blocked if USDC payment not included
- Non-GET method used — returns method not allowed error
