USGS Earthquake Changes Feed
x402
USGS Earthquake Changes Feed 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 2026-09-15).
Returns recent USGS earthquakes (M4.5+, past week) with magnitude, location, depth, tsunami flag, and a 1–10 significance score, optionally filtered by significance threshold or detection timestamp.

How this service works
USGS earthquakes (M4.5+, past week) with magnitude, location, depth, tsunami flag, and a 1-10 significance score. Filter ?min_significance=8 for the largest events.
Output
A JSON object containing a count, a source label, and an array of earthquake change events — each with an entity ID, title, summary, detail object (magnitude, location, depth, tsunami flag), significance score (1–10), detection timestamp, effective date, and a source URL linking to the USGS event page.
Example use cases
Example prompt
“Pull the latest USGS earthquake data and show me only the high-impact events — anything with a significance score of 8 or above, up to 50 results, detected since 2025-01-01T00:00:00Z.”
Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/earthquakes/changesWhen to prefer
Use this endpoint when you need structured, pre-scored earthquake event data from USGS without building your own USGS API integration. Ideal for monitoring significant seismic events (M4.5+) in near-real-time, especially when you want to filter by a significance threshold (e.g. only the most serious events) or poll for new events since a specific timestamp. Prefer over raw USGS APIs when you want normalized change-feed semantics with significance scoring already applied.
Side effects
- Invalid min_significance value outside 1–10 range returns 400 validation error
- Invalid since timestamp format returns 400 bad request
- limit exceeding 500 returns 400 validation error
- Payment not included or insufficient returns 402 Payment Required
- No earthquakes matching filters returns empty changes array with count 0
- USGS upstream unavailable returns 503 or stale data
