## 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 coin-railz-risk-metrics-var-sharpe-drawdown-analysis-dfe79a67 -d '<json body>'
```

Example prompt: Can you run a full risk analysis on my Bitcoin and Ethereum portfolio — I need the Value at Risk, Sharpe ratio, and maximum drawdown figures so I can decide whether to rebalance before the market opens?

## When to prefer this

Choose this endpoint when you need quantitative, multi-dimensional risk metrics (VaR + Sharpe + drawdown together) for crypto or financial assets in a single call, especially within an autonomous agent workflow that can handle x402 micropayments. Prefer this over general market sentiment endpoints when the user needs rigorous statistical risk quantification rather than qualitative signals.

## Known failure modes

- Invalid or missing portfolio/asset data returns an error response
- Insufficient historical data for the requested time horizon may produce unreliable metrics
- Malformed request body causes a 400-level error
- Payment failure via x402 protocol prevents execution
- Service outage or timeout returns a non-200 status with error message
