How this service works
Pay-per-call access to public-domain data (USGS earthquakes, NOAA/NWS forecasts, World Bank indicators) plus an x402 endpoint pre-payment checker over x402 on Base USDC. No account or API key.
Output
A GeoJSON FeatureCollection object containing earthquake event features, each with properties such as magnitude, place name, time, coordinates, and other USGS seismic metadata.
Example use cases
Real-time significant earthquake alert
“Can you grab the USGS significant_hour earthquake feed right now and tell me if any major earthquakes just happened in the last hour?”
Weekly seismic activity overview
“Fetch the USGS all_week earthquake feed and give me a summary of all seismic events recorded globally over the past 7 days.”
High-magnitude quake monitoring
“Get the USGS 4.5_week earthquake feed and list any magnitude 4.5 or higher earthquakes from the past week, including their locations and depths.”

Side effects
- Invalid or unrecognized feed name in URL path returns an error or empty result
- Payment not fulfilled (402 response) if x402 pre-payment check fails or USDC not sent
- USGS upstream outage may result in stale or empty feature arrays
- Malformed path parameter causes 404 or unexpected response
