Foundry USGS Earthquake Radius + Time Window Query
x402
Foundry USGS Earthquake Radius + Time Window Query is a paid API for AI agents from foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Returns USGS earthquake catalog events within a geographic radius and time window, filtered by minimum magnitude, with source provenance and completeness evidence.

How this service works
Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.
Output
A JSON object containing the echoed query parameters, a list of earthquake events (each with USGS identifiers, magnitude, location, and time), a 'complete' boolean indicating whether the result was truncated, an evidence block with source URL, attribution, retrieval timestamp, cache age, and upstream call count, plus a limitations array and observed_at timestamp.
Example use cases
Post-event seismic activity audit
“Were there any earthquakes magnitude 4.0 or greater within 200 km of Anchorage (61.22, -149.90) between 2024-11-01T00:00:00Z and 2024-11-30T00:00:00Z? Give me up to 10 results with source evidence.”
Insurance claim seismic verification
“I need to verify whether USGS recorded any earthquakes near Napa, CA (38.30, -122.28) within a 50 km radius on 2024-08-14 — specifically between 2024-08-14T00:00:00Z and 2024-08-15T00:00:00Z, any magnitude, up to 5 events.”
Real-time seismic monitoring alert check
“Check the USGS catalog for any earthquakes in the past 24 hours within 300 km of Mexico City (19.43, -99.13), minimum magnitude 3.0, up to 20 events — I want to see the source provenance too.”

Endpoint
POSThttps://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/official/usgs-radius-incident-windowWhen to prefer
Use this endpoint when you need official, source-attributed USGS earthquake records for a specific geographic area and time window — especially for evidence, audit, or verification use cases where provenance and completeness flags matter. Prefer it over generic web searches when you need structured JSON with explicit source metadata and public-domain licensing. It is bounded to a single spatial+temporal query per call.
Side effects
- Invalid date-time format (must be ISO 8601 UTC with Z suffix) returns validation error
- radius_km of 0 or negative rejected by exclusiveMinimum constraint
- latitude outside -90 to 90 or longitude outside -180 to 180 returns schema error
- limit exceeding 20 rejected
- No events in range returns empty events array with complete:true (not an error)
- USGS upstream unavailability may cause delayed or failed responses
- Payment not included or insufficient USDC returns 402
