## 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 kihustle-sortino-ratio-calculator-be8eb192 -d '<json body>'
```

Example prompt: Calculate the Sortino ratio for these monthly portfolio returns: [0.02, -0.01, 0.03, 0.015, -0.005, 0.04, 0.01, -0.02] with a risk-free rate of 0.005.

## When to prefer this

Choose this endpoint when you need a quick, low-cost computation of the Sortino ratio for a given set of returns and a risk-free rate. It is ideal for agents performing portfolio analytics, backtesting strategy screening, or generating client-facing performance reports where downside-risk-adjusted return is specifically needed rather than the Sharpe ratio.

## Known failure modes

- Empty or missing returns array causes processing failure
- Non-numeric values in the returns array result in an error
- All returns above the risk-free rate yields undefined or infinite Sortino ratio (no downside deviation)
- Missing risk_free parameter may default or error depending on implementation
- Too few data points may produce statistically unreliable results
