How this service works
Real-time earthquake data from USGS. Query recent earthquakes by time period and minimum magnitude. Optionally filter by geographic radius. Returns magnitude, location, depth, and tsunami warnings.
Output
Returns a list of earthquakes sorted newest first, each with magnitude, human-readable location, ISO 8601 timestamp, latitude/longitude, depth in km, tsunami warning boolean, optional alert level (green/yellow/orange/red), and a USGS detail URL — plus a total count and the queried time period.
Example use cases
Example prompt
“Show me all earthquakes of magnitude 4.5 or greater that happened in the last week within 500 km of Tokyo (latitude 35.68, longitude 139.69), and flag any tsunami warnings.”
Technical details
Endpoint
POSThttps://quakes.withzero.ai/runWhen to prefer
Use this endpoint when you need real-time or recent USGS earthquake data with flexible filtering by time window, magnitude threshold, and geographic area. Ideal for monitoring seismic activity, alerting on tsunami warnings, or building disaster-awareness features. Prefer this over static datasets when up-to-the-minute data matters.
Side effects
- Invalid period enum value returns validation error
- minMagnitude must be one of the allowed enum strings, not a raw number
- maxRadiusKm must be greater than 0 (exclusiveMinimum)
- latitude/longitude out of range (-90 to 90 and -180 to 180) returns error
- If lat/lon provided without maxRadiusKm, defaults to 500 km radius
- USGS upstream unavailable may return 503 or empty results
- No earthquakes matching criteria returns empty array with total=0
