## How to call it through Zero

```sh
zero fetch --capability api-carbon-cashmere-de-6d699c62
```

Example prompt: Check the Carbon Cashmere events feed for any whale transactions, price spikes, or ML anomaly alerts on BTC in the last 60 minutes, filtering for high severity events only.

## When to prefer this

Use this endpoint when you need a unified, aggregated feed of significant crypto market events (whale activity, regime shifts, funding extremes, price spikes, ML anomalies) without maintaining a persistent WebSocket or webhook connection. Ideal for periodic polling workflows, agent-based monitoring loops, or building event-driven alerts on a 1-5 minute cadence without push infrastructure.

## Known failure modes

- Invalid event type filter returns 400 or empty results
- Window parameter out of range (>1440 min) causes error
- Rate limiting if polled too frequently (below 60s cache window)
- No events returned if no qualifying events fired in the requested window
- Unknown coin filter silently returns empty results
