How this service works
Returns seismic events as GeoJSON from the USGS FDSN service (earthquake.usgs.gov/fdsnws/event/1/query): magnitude, place, time, depth and coordinates filtered by time window and minimum magnitude. Autonomous agents and agent-to-agent (A2A) disaster-response, insurance-risk and infrastructure-monitoring systems poll it for recent quakes. Ranking surface: region/time to magnitude-ranked events. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
Returns a JSON object with a success flag, a count of matching events, and an array of earthquake records each containing event ID, Unix timestamp, depth in km, place name, latitude, longitude, and magnitude. Provenance metadata (source URL and label) is included.
Example use cases
Disaster response real-time alerting
“Check the USGS earthquake feed for any quakes magnitude 6.0 or higher that happened in the last 12 hours and give me up to 20 results — I need this for our disaster response dashboard.”
Insurance risk batch review
“Pull me all earthquakes of magnitude 4.5 or above between January 1 and March 31 2025, up to 100 events, so I can assess seismic exposure for our property insurance portfolio.”
Infrastructure monitoring weekly digest
“Get me the top 10 most significant earthquakes from the past week — anything magnitude 5.0 or stronger — so our infrastructure team can review potential impact zones.”
Technical details
Endpoint
POSThttps://usgs-earthquake-events.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need fast, pay-per-call access to USGS earthquake catalog data without managing USGS API authentication or rate limits yourself. It is ideal for autonomous agents, A2A pipelines, and polling loops in disaster-response, insurance-risk, or infrastructure-monitoring workflows that need structured GeoJSON-ready earthquake data ranked by magnitude within a specific time window.
Side effects
- Invalid or malformed date strings for starttime/endtime return an error response
- No earthquakes matching the filters return a result with count 0 and empty array
- Upstream USGS FDSN service outage causes failed or delayed responses
- Extremely broad time windows or low magnitude thresholds may hit result limits or time out
- Non-integer minmagnitude or limit values may cause schema validation errors
