x402
USGS Earthquake Event Lookup is a paid API for AI agents from foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Resolves a single USGS earthquake event ID into its current factual record from the USGS Earthquake Catalog, including event metadata and seismic network attribution.

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 queried event ID, source attribution to the USGS Earthquake Catalog, freshness/cache metadata (retrieval timestamp, cache age, max cache seconds), provenance details (license, terms URL, upstream call count, documentation URL), and a normalizedResult array with the earthquake event fields. Includes observedAt timestamp and sourceUrl pointing to earthquake.usgs.gov.
Example use cases
Verify reported earthquake event details
“I saw a news report referencing USGS earthquake event us7000m9g4 — can you look that up and give me the official details from the USGS catalog?”
Enrich seismic alert with event metadata
“We just got an alert with USGS event ID nc73921360 — can you fetch the full earthquake record for that event so I can include it in our incident report?”
Research historical earthquake by known ID
“I have a list of USGS earthquake event IDs from last year — start with us6000jllz and pull the catalog record so I can see the magnitude, location, and which seismic network reported it.”

Endpoint
POSThttps://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/official/usgs-earthquake-eventWhen to prefer
Use this endpoint when you have a specific USGS earthquake event ID and need to resolve it to a full catalog record. Prefer this over the list/search earthquake endpoint when you already know the exact event identifier. It provides authoritative USGS public-domain data with provenance tracking, making it suitable for compliance, reporting, and research workflows where source attribution matters.
Side effects
- Invalid or malformed event_id (must be 5-40 alphanumeric characters) returns a validation error
- Unknown or non-existent event ID returns an empty normalizedResult array
- USGS upstream unavailability may result in stale or failed retrieval
- Payment not completed via x402 USDC results in 402 response before data is returned
