How this service works
Paid public-data feeds. Unpaid requests return HTTP 402. Prices are USDC on Base.
Output
A JSON object containing an array of slim GeoJSON earthquake event features from the USGS, each including location, magnitude, time, and a UI link to the USGS event page. The response also includes metadata about the source endpoint and a label describing the data type.
Example use cases
Daily seismic activity briefing
“Get me all earthquakes from the USGS that happened in the last 24 hours with a magnitude of at least 3.0, up to 50 results, ordered by time — I want a quick daily briefing.”
Major quake alert monitoring
“Fetch USGS earthquake events from the past 30 days with a minimum magnitude of 6.0, limit to 10 results ordered by magnitude, so I can track the biggest quakes this month.”
Research dataset for a specific period
“I need USGS earthquake data from January 1 2024 to January 31 2024 with no magnitude filter and up to 100 results ordered by time for a research project.”
Technical details
Endpoint
GEThttps://project-api-gamma-sable.vercel.app/paid/usgs/earthquakes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, pay-per-call access to USGS earthquake event data via a Web3-native x402 micropayment flow on Base (USDC). It is ideal for agents that need real-time or historical seismic data without managing API keys, subscriptions, or OAuth — just a $0.01 USDC payment per query. Prefer this over direct USGS API calls when operating in an autonomous agent context that already handles x402 payments.
Side effects
- HTTP 402 returned if payment header is missing or invalid — requires x402 USDC payment on Base
- Empty items array if no earthquakes match the specified filters
- Invalid date format in starttime/endtime causes query failure
- minmagnitude out of valid range may return unexpected results or an error
- Rate limiting or upstream USGS API downtime may cause delayed or failed responses
