# SelectaRank Data Gateway – USGS Earthquake Feed

> SelectaRank Data Gateway – USGS Earthquake Feed is a paid API for AI agents from selectarank-data.vercel.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Fetches USGS earthquake GeoJSON feed data (by feed type) via pay-per-call micro-payment on Base USDC with 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 selectarank-data-gateway-usgs-earthquake-feed-da9f1cd6
```

Example prompt: Pull the USGS significant earthquakes from the last hour — I want the full GeoJSON feed so I can see what major seismic events just happened worldwide.

## When to prefer this

Choose this endpoint when you need USGS earthquake GeoJSON data without registering for an API key or maintaining a subscription — ideal for lightweight, pay-per-call agent workflows that only occasionally need seismic data and want to pay $0.002 USDC per call via x402 on Base.

## Known failure modes

- Invalid or unrecognized feed name in URL path returns an error or empty result
- Payment not fulfilled (402 response) if x402 pre-payment check fails or USDC not sent
- USGS upstream outage may result in stale or empty feature arrays
- Malformed path parameter causes 404 or unexpected response

## How this service works

Pay-per-call access to public-domain data (USGS earthquakes, NOAA/NWS forecasts, World Bank indicators) plus an x402 endpoint pre-payment checker over x402 on Base USDC. No account or API key.

## Output

A GeoJSON FeatureCollection object containing earthquake event features, each with properties such as magnitude, place name, time, coordinates, and other USGS seismic metadata.
