## 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 xynaptic-security-risk-2da45ee4
```

Example prompt: What's the risk profile for NVDA over the last 180 days — I need the volatility, max drawdown, VaR 95, and Sharpe proxy, and whether it's classified as low, medium, high, or extreme risk.

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-metric quantitative risk profile for a single equity ticker derived from historical price data — especially when you want a pre-computed risk classification (low/medium/high/extreme) alongside standard risk metrics like VaR, drawdown, and Sharpe proxy in one call, without needing to query raw price data and compute these yourself.

## Known failure modes

- Unknown or invalid ticker returns an error or empty metrics
- Insufficient price history for the requested days window may cause missing or null metrics
- Beta vs SPY may be unavailable if correlation data is insufficient
- Rate limit or payment failure returns a 402 or 429 error
- Very short day windows may produce unstable or unreliable risk estimates

## How this service works

Xynaptic Security Risk — risk profile from price history: annualized volatility, max drawdown, worst day, VaR 95 (parametric), Sharpe proxy, beta vs SPY (when available). GET ?ticker=AAPL&days=180. Output: risk_level (low/medium/high/extreme) + each metric with its window.

## Output

Returns a structured JSON object with a top-level risk_level label (low/medium/high/extreme) plus individual metrics each tagged with their calculation window: annualized volatility, max drawdown, worst single-day return, parametric VaR at 95% confidence, a Sharpe proxy, and beta relative to SPY (when sufficient data is available).
