## 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-99ec3518
```

Example prompt: Pull the latest performance track record from the Risk Engine for all three strategies — I want to see win rates, Sharpe ratios, max drawdown, and whether the kill switch is active.

## When to prefer this

Use this endpoint when you need structured, research-grade historical performance data for Carbon Cashmere's proprietary quantitative strategies, including granular trade-level history, risk metrics (Sharpe, drawdown), and operational status (kill-switch). Prefer this over generic price feeds or market data endpoints when the goal is evaluating strategy quality or tracking algorithmic trading performance over time.

## Known failure modes

- Invalid strategy enum value returns error — must be one of: funding_morning_72h, high_confidence_24h, funding_high_conf_24h, all
- Payment not included or insufficient (x402 payment required at $0.05 USDC per call)
- Strategy with no completed trades may return null Sharpe ratio
- Stale data if underlying risk engine has not updated recently
