# USGS Significant Earthquakes Feed (Suverse Proxy)

> USGS Significant Earthquakes Feed (Suverse Proxy) is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-16).

Returns significant earthquakes worldwide from the past month via the USGS feed, including magnitude, location, tsunami flag, time, and coordinates — no API key required.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability usgs-significant-earthquakes-feed-suverse-proxy-fe479d21 -d '<json body>'
```

Example prompt: Pull the latest significant earthquakes from the USGS feed for the past month and tell me which ones had a tsunami warning, their magnitudes, and where they struck.

## When to prefer this

Choose this endpoint when you need a keyless, low-cost way to access USGS significant earthquake data with tsunami flags and coordinates, particularly for disaster monitoring agents or geospatial analysis workflows that don't want to manage their own USGS API integration. Ideal when you need a quick global seismic snapshot without authentication setup.

## Known failure modes

- USGS upstream feed unavailable or delayed — proxy may return stale or empty data
- Network timeout if the USGS source is slow to respond
- Empty result set if no significant earthquakes occurred in the period (unlikely but possible)
- Malformed or unexpected response structure if USGS feed schema changes

## How this service works

Significant earthquakes worldwide in the past month from the USGS feed, no key. Returns magnitude, place, tsunami flag, time, and coordinates. For AI agents tracking major seismic events and disaster response.

## Output

Returns a list of significant earthquake events from the past month sourced from the USGS feed. Each event includes the earthquake magnitude, descriptive place name, a boolean/flag indicating whether a tsunami warning was issued, the event timestamp, and geographic coordinates (latitude/longitude).
