## How to call it through Zero

```sh
zero fetch --capability api-carbon-cashmere-de-dfff0ca9
```

Example prompt: Pull me the full Carbon Cashmere BTC bundle right now — I want the price, ML ensemble signal, orderbook, on-chain metrics, fear and greed index, funding rates, and current market regime all at once.

## When to prefer this

Use this endpoint when you need a comprehensive snapshot of Bitcoin market conditions from a single call rather than assembling multiple separate API calls. Ideal when you want ML signals, price, sentiment, and on-chain data together for trading decision support or market monitoring dashboards.

## Known failure modes

- HTTP 402 if payment is not provided or insufficient USDC balance
- Stale data if upstream data sources are delayed
- Partial bundle if a sub-component (e.g. on-chain node) is temporarily unavailable
- Network timeout if the aggregation takes too long
