## 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 x402-quantitative-risk-snapshot-cdd77acb -d '<json body>'
```

Example prompt: Run a quantitative risk snapshot on my portfolio returns data — I need the risk label, risk score, max drawdown, annualized volatility, and total return so I can see where it falls on the risk spectrum.

## When to prefer this

Choose this endpoint when you need a fast, affordable ($0.01 USDC), deterministic quantitative risk profile — including drawdown, volatility, risk score, and a categorical risk label — computed from provided financial data. It is well-suited for AI agents that need lightweight, pay-per-request risk analytics without subscribing to a full financial data platform.

## Known failure modes

- Missing or malformed input price/returns data returns an error
- Insufficient observations may produce unreliable or zero volatility metrics
- Payment failure via x402 protocol results in 402 response and no data returned
- Invalid request body format returns a parsing or validation error

Pay-per-request data tools for AI agents.

## Output

Returns a JSON object with a risk_label (e.g. 'moderate'), a numerical risk_score, max_drawdown_pct, total_return_pct, downside_deviation_pct, annualized_volatility_pct, and the number of observations used. Includes a disclaimer that output is deterministic research only, not financial advice.
