# Suverse Earthquake Radius Search

> Suverse Earthquake Radius Search is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.06/call, status unknown (last checked 2026-09-14).

Returns GeoJSON earthquake features from USGS for all quakes within a given radius of a lat/lon coordinate, filtered by minimum magnitude and start date.

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 suverse-earthquake-radius-search-86b389e1 -d '<json body>'
```

Example prompt: Can you find all earthquakes of magnitude 4.0 or greater within 200km of San Francisco (37.7749, -122.4194) since January 1, 2024?

## When to prefer this

Choose this endpoint when you need keyless, pay-per-call access to USGS earthquake data centered on an arbitrary lat/lon coordinate with configurable radius, magnitude threshold, and date filter. It is ideal for location-aware applications, real-time seismic risk assessments, or when you want structured GeoJSON output without managing a USGS API integration yourself. Prefer this over direct USGS API calls when you need a simple proxied interface with predictable pricing and no API key management.

## Known failure modes

- Invalid or out-of-range latitude/longitude values cause a 400 error
- Radius or magnitude values outside accepted bounds return an error
- Malformed start date format causes a parsing error
- No earthquakes matching criteria returns an empty GeoJSON feature list
- USGS upstream outage may cause delayed or failed responses
- Missing required body fields results in a 400 bad request

## How this service works

Find earthquakes near any point. Pass latitude, longitude and a search radius (km) plus minimum magnitude and start date; returns GeoJSON quake features from USGS. Keyless. Ideal for location-aware seismic risk checks.

## Output

A GeoJSON FeatureCollection where each feature represents an earthquake event, including coordinates (longitude, latitude, depth), magnitude, event time, place description, and USGS event ID. The response is directly from the USGS Earthquake Hazards Program feed, filtered to match the specified radius, minimum magnitude, and date range.
