# USGS Earthquake Feed (via Suverse Proxy)

> USGS Earthquake Feed (via Suverse Proxy) is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.055/call, status unknown (last checked 2026-09-14).

Queries the USGS FDSN live earthquake feed by date range and minimum magnitude, returning GeoJSON features with seismic event details.

## Facts

- Endpoint: POST https://proxy.suverse.io/v1/data/suverse-earth-quake-feed
- Price: $0.055/call
- Payment: x402
- Status: unknown

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-earthquake-feed-via-suverse-proxy-867fed40 -d '<json body>'
```

Example prompt: Can you pull the latest USGS earthquake data for the past 7 days and show me all events with a magnitude of 5.0 or higher, including their location and coordinates?

## When to prefer this

Choose this endpoint when you need authoritative, keyless seismic event data directly from USGS without setting up your own FDSN client. Ideal for agents that need to monitor, alert on, or research earthquake activity by date range and magnitude threshold. Prefer over scraping USGS directly since this proxy handles the FDSN protocol and returns clean GeoJSON suitable for immediate agent consumption.

## Known failure modes

- Invalid or missing date range parameters causing empty or error response
- Minimum magnitude threshold too high returning zero results for quiet periods
- Date range too broad causing timeout or oversized response
- USGS/FDSN upstream service outage returning proxy error
- Malformed POST body or incorrect bodyType causing 400-level error

## How this service works

Live earthquake feed from USGS (FDSN). Query by start/end date and minimum magnitude; returns GeoJSON features with magnitude, place, time and coordinates. Keyless, authoritative seismic data for monitoring, alerting and research.

## Output

Returns a GeoJSON FeatureCollection where each Feature represents one seismic event, including properties such as magnitude, human-readable place name, UTC timestamp, and geometry (longitude, latitude, depth in km).
