## 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 carbon-cashmere-signal-api-sol-decision-endpoint-31e8cfb1
```

Example prompt: What's the current Carbon & Cashmere signal for SOL — give me the conviction score, market regime, and whether the ML model says long or short right now.

## When to prefer this

Use this endpoint when you need a fast, single-call, opinionated trading signal for SOL that combines price data, ML ensemble direction, market regime classification, and conviction scoring into one response. Prefer it over raw price feeds when you need actionable intelligence rather than just a quote, and over broader bundle endpoints when you only need SOL and want to minimize cost per call.

## Known failure modes

- Coin not tracked — returns 404 or empty result if the symbol is unsupported
- Stale data — market data may lag during exchange outages or low liquidity
- Payment failure — x402 micropayment not processed, returns 402 Payment Required
- Rate limiting — too many calls in a short window returns 429
- Network timeout — upstream data source unavailable returns 503

## How this service works
