How this service works
Real-time earthquake feed. Recent seismic events from USGS with magnitude, location, depth, and tsunami flag, filterable by magnitude, time, and radius.
Output
A list of recent earthquake events from the USGS catalog, each with magnitude, location name, coordinates, depth, event timestamp, and a tsunami flag, filtered according to the requested magnitude threshold, time window, and geographic radius.
Example use cases
Example prompt
“What earthquakes of magnitude 4.0 or higher occurred within 300 km of San Francisco over the past 3 days — include any tsunami warnings?”
Technical details
Endpoint
GEThttps://api.kadec0.xyz/v1/usgs-quakesWhen to prefer
Use this endpoint when you need live or recent USGS earthquake data with flexible filtering by magnitude, time, and geography. Prefer this over static datasets when real-time seismic monitoring or event-driven alerting is needed, and over general web search when structured, machine-readable earthquake records are required.
Side effects
- No events found matching filters — returns empty list
- Invalid ISO date format for starttime/endtime — returns 400 error
- latitude/longitude provided without maxradiuskm — radius search ignored or error
- minmagnitude below USGS threshold may return very large result sets
- Service unavailable if USGS upstream feed is down
