## 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 24k-labs-return-risk-metrics-calculator-ae5f0c2d -d '<json body>'
```

Example prompt: Calculate the CAGR, annualized volatility, Sharpe ratio (using a 4.5% risk-free rate), and maximum drawdown for this series of monthly portfolio values: [100, 108, 115, 104, 120, 135, 128, 142, 155, 149, 162, 170].

## When to prefer this

Choose this endpoint when you need a comprehensive set of quantitative investment performance and risk metrics — especially CAGR, Sharpe ratio, and maximum drawdown — computed in a single call from a price or value series. Prefer it over building calculations manually or calling separate analytics APIs when you need a fast, cheap ($0.003), self-contained computation that covers both return and risk dimensions simultaneously.

## Known failure modes

- Insufficient data points in series for meaningful volatility or drawdown computation
- Missing required inputs (no series provided and no start/end/years combination)
- Risk-free rate not provided when Sharpe ratio is requested
- Non-numeric values in the series causing parsing errors
- Zero or negative start value causing division errors in return calculations
- Series with fewer than 2 data points returning an error

## How this service works

From a value series (or start/end/years): CAGR, total return, annualized volatility, Sharpe ratio (given risk-free) and maximum drawdown.

## Output

Returns a JSON object containing: CAGR (compound annual growth rate as a percentage), total return (percentage), annualized volatility (standard deviation of returns annualized), Sharpe ratio (excess return per unit of risk given the risk-free rate), and maximum drawdown (largest peak-to-trough decline in the series).
