How this service works
USGS earthquakes (significant, past month) 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 attribution, and an array of earthquake change events — each containing an entityId, title, summary, detectedAt timestamp, effectiveDate, a 1–10 significance score, a detail object with magnitude/location/depth/tsunami flag, and a sourceUrl linking to the USGS event page.
Example use cases
Example prompt
“What are the most significant earthquakes from the past month? Show me only the ones with a significance score of 8 or higher, up to 20 results.”
Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/earthquakes-significant/changesWhen to prefer
Choose this endpoint when you need a scored, pre-filtered list of globally significant earthquakes from USGS with a structured significance ranking (1–10), especially when you want to programmatically threshold on importance (e.g. only score ≥ 8) or detect changes since a specific timestamp. Prefer this over raw USGS feeds when you want normalized significance scoring and change-detection semantics rather than raw earthquake catalog queries.
Side effects
- Invalid min_significance value outside 1–10 range returns a 400 error
- Invalid since date-time format returns a 400 validation error
- No earthquakes matching filters returns an empty changes array with count 0
- Payment not included or insufficient returns 402 Payment Required
- Service downtime or upstream USGS API unavailability returns 5xx error
