## 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 api-carbon-cashmere-de-6c4df470
```

Example prompt: Give me the full market intelligence bundle for BTC — ML ensemble signal, HMM regime, Fear & Greed Index, funding rates, orderbook microstructure, news sentiment, and on-chain data all in one shot.

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one crypto market intelligence snapshot for a single coin and want to avoid making multiple separate API calls for ML signals, regime, sentiment, on-chain, and orderbook data. Ideal for AI agents performing holistic market research or building dashboards that require multiple data dimensions simultaneously. Prefer individual specialized endpoints if you only need one data type (e.g., just orderbook or just ML signal) to avoid the $0.15 per-call cost for partial data needs.

## Known failure modes

- Unsupported coin ticker returns 400 or validation error — only 34 listed tickers are accepted
- Payment not provided or x402 payment failure results in 402 response
- Upstream data source unavailability may cause partial or degraded response
- Rate limiting or quota exhaustion returns 429
- Network timeout on slow on-chain data fetch
