Earthquake Radius Search API
x402
Earthquake Radius Search API is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Returns all earthquakes above a minimum magnitude within a specified radius of a given latitude/longitude, sourced from the official government seismic real-time catalog, as normalized JSON.

How this service works
Earthquake radius search API: every earthquake above a minimum magnitude within a given radius of any latitude/longitude, from the official government seismic real-time seismic catalog — magnitude, depth, location, time, and tsunami flag — as normalized JSON. Built for site-specific risk checks (a facility, a shipment, a property) rather than a global feed.
Output
A normalized JSON array of earthquake events matching the search criteria, each containing magnitude, depth, geographic location, timestamp, and a tsunami flag, sourced from the official government real-time seismic catalog.
Example use cases
Example prompt
“Are there any earthquakes above magnitude 2.5 within 100 km of San Francisco (37.77, -122.42) in the recent seismic catalog?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/earthquake-radius-searchWhen to prefer
Use this endpoint when you need site-specific seismic risk data for a precise location — such as a facility, property, or asset — rather than a broad global or regional earthquake feed. It is ideal for point-in-time risk checks, insurance assessments, or logistics routing where you need magnitude, depth, and tsunami flags for a defined geographic radius.
Side effects
- Invalid or out-of-range latitude/longitude values result in an error or empty response
- Radius too large may return excessive results or timeout
- No earthquakes above minimum magnitude in the specified radius returns an empty array
- Invalid magnitude threshold (non-numeric or negative) causes a request error
- Payment failure (insufficient USDC) blocks the request
