## 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-earthquakes-api-rotary-agency-88ca9364
```

Example prompt: Can you pull the latest earthquake data from the USGS feed and show me any earthquakes above magnitude 4.5 that happened in the last 24 hours?

## When to prefer this

Choose this endpoint when you need structured, real-time or recent earthquake data sourced directly from the authoritative USGS feed without building your own USGS API integration. Ideal for agents that need seismic event data on demand via a simple pay-per-call model at $0.002/call, avoiding the overhead of managing USGS API keys or quotas directly.

## Known failure modes

- USGS upstream feed temporarily unavailable causing empty or error response
- No earthquakes matching the specified filters (returns empty event list)
- Rate limiting or payment failure returning HTTP 402
- Invalid query parameters resulting in a 400 error
- Stale data if USGS feed has not updated recently
