# USGS Earthquake Feed

> USGS Earthquake Feed is a paid API for AI agents from x402-deployer.x402-deployer.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Returns recent earthquakes from USGS for a specified time window and minimum magnitude, including location, magnitude, depth, tsunami flag, and felt-report count.

## Facts

- Endpoint: POST https://x402-deployer.x402-deployer.workers.dev/earthquakes-recent
- Price: $0.002/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 x402-deployer-x402-deployer-workers-dev-7cadaebf -d '<json body>'
```

Example prompt: Pull the USGS earthquake feed for the past week and show me all quakes with magnitude 5 or higher, including their location, depth, and whether any triggered a tsunami warning.

## When to prefer this

Use this endpoint when you need structured, up-to-date earthquake data from the authoritative USGS source without setting up your own USGS GeoJSON feed parsing. Ideal for agents monitoring seismic activity, building disaster-awareness features, or answering user questions about recent earthquakes globally. Prefer this over raw USGS API access when you want a simple POST interface with clean per-event fields already parsed out.

## Known failure modes

- Invalid time window value returns an error (valid options: hour, day, week, month)
- Invalid or out-of-range magnitude threshold may return empty results or an error
- USGS upstream feed unavailable causes a service error
- Malformed POST body causes a 400 bad request
- No earthquakes matching the filter returns an empty list

## How this service works

Earthquake feed. Returns recent earthquakes from USGS for any time window (hour, day, week, month) above a magnitude threshold. Includes location, magnitude, depth, tsunami flag. Each quake includes magnitude + type, depth (km), place, ISO8601 time, lat/lon, tsunami flag, USGS event URL, and felt-report count when available. Wraps USGS GeoJSON summary feeds — public domain, no auth.

## Output

A list of recent earthquake events from the USGS GeoJSON summary feed, each including magnitude and type, depth in kilometers, place description, ISO8601 timestamp, latitude/longitude coordinates, tsunami flag, USGS event URL, and felt-report count where available.
