How this service works
Real-time earthquakes (official USGS FDSN). POST {minmagnitude?, starttime?, endtime?, limit?}. Returns {count, quakes: [{magnitude, place, time, depth_km, lat, lon, tsunami}]}.
Output
Returns a count of matching events and an array of earthquake objects, each containing magnitude, descriptive place name, UTC timestamp, depth in kilometers, latitude, longitude, and a boolean tsunami flag indicating whether a tsunami was triggered.
Example use cases
Daily seismic activity briefing
“Give me a summary of all earthquakes magnitude 4.5 or higher from the past 24 hours — include location, depth, and whether any triggered a tsunami alert.”
Post-event aftershock monitoring
“Fetch up to 50 earthquakes from USGS starting January 1, 2025 through January 7, 2025 with a minimum magnitude of 3.0, so I can see the aftershock sequence.”
Research strongest recent quakes
“What were the top 20 earthquakes worldwide since March 1, 2025 with magnitude 6.0 or above? I want to know where they happened and how deep they were.”

Endpoint
GEThttps://x402-seller-202595743428.europe-west1.run.app/quakesWhen to prefer
Choose this endpoint when you need real-time or recent historical earthquake data sourced directly from the authoritative USGS FDSN feed. It is ideal for monitoring seismic activity, building disaster-response workflows, or enriching geospatial alerts with official government data. Prefer it over scraped or third-party aggregators when data authority and accuracy are critical.
Side effects
- Date range too broad may return truncated results capped at the limit parameter
- Invalid ISO datetime format in starttime/endtime returns a 400 error
- Limit exceeds maximum of 50 returns a validation error
- No earthquakes match the given filters returns count:0 and empty quakes array
- Upstream USGS FDSN service downtime causes 502 or timeout responses
