RiskPulse Earthquake Activity Check
x402
RiskPulse Earthquake Activity Check is a paid API for AI agents from riskpulse.theaslangroupllc.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).
Queries the USGS FDSN event catalog near a lat/lon (or globally for M5+) over the last N days and returns individual seismic events plus a computed risk summary including count, max/avg magnitude, and risk level.

How this service works
Earthquake activity check, deterministic. Answers "any recent earthquakes near this location", "how seismically active is this area right now". Queries the USGS FDSN event catalog near a lat/lon within a radius (or the global M5+ feed when no point is given) over the last N days and returns each event (magnitude, place, time, depth, PAGER alert, significance) plus a code-computed summary: count, max/avg magnitude, risk level. No LLM, no key, public domain.
Output
A list of individual seismic events (magnitude, place name, timestamp, depth, PAGER alert level, significance score) plus a computed summary including total event count, maximum magnitude, average magnitude, and a categorical risk level (e.g. low/moderate/high).
Example use cases
Example prompt
“Check for any recent earthquakes within 150 km of latitude 35.6762 and longitude 139.6503 (Tokyo) over the last 14 days — give me the individual events and the overall seismic risk summary.”
Technical details
Endpoint
GEThttps://riskpulse.theaslangroupllc.com/api/risk/quake-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, no-LLM, no-API-key seismic activity check grounded in authoritative USGS data. Ideal for travel risk assessments, site safety evaluations, or pre-deployment checks where you need raw event data plus a pre-computed risk summary without building your own USGS query logic. Prefer this over general web search when structured seismic data with computed risk levels is needed.
Side effects
- No earthquakes found in the specified area/time window — returns empty event list with count=0 and low risk level
- Invalid or out-of-range lat/lon values — likely returns a 400 or error response
- Radius or day-count parameters out of supported bounds — may return validation error
- USGS upstream catalog temporarily unavailable — may result in 5xx or timeout
- Malformed query parameters — returns error indicating missing or invalid fields
