x402
USGS Earthquake Feed with Significance Scoring is a paid API for AI agents from oracles-production.up.railway.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).
Returns recent USGS earthquakes (M2.5+, past day) with magnitude, location, depth, tsunami flag, and a 1–10 significance score, optionally filtered by significance threshold or timestamp.

How this service works
USGS earthquakes (M2.5+, past day) with magnitude, location, depth, tsunami flag, and a 1-10 significance score. Filter ?min_significance=8 for the largest events.
Output
A JSON object with a count, source label, and an array of earthquake change events, each containing an entity ID, title, summary, detected timestamp, significance score (1–10), tsunami flag, magnitude, depth, location, and a primary-source USGS URL for verification.
Example use cases
Example prompt
“Pull the latest USGS earthquakes from the past day and only show me the ones with a significance score of 8 or higher — I want to know about any major or tsunamigenic events.”
Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/earthquakes-all/changesWhen to prefer
Use this endpoint when you need a real-time, scored feed of recent global earthquakes with a significance ranking, especially for automated alerting on high-impact seismic events. Prefer this over raw USGS feeds when you want pre-computed significance scores and change-detection semantics. Use the sibling detail endpoint for full metadata on a specific earthquake entity.
Side effects
- No events returned if no M2.5+ earthquakes occurred in the past day
- min_significance too high (e.g. 10) may return zero results on quiet days
- Invalid since timestamp format returns a validation error
- limit exceeding 500 rejected by schema validation
- Payment failure (402) if USDC balance is insufficient
