## 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-sharpe-ratio-calculator-11cafa75 -d '<json body>'
```

Example prompt: Can you calculate the Sharpe ratio for my portfolio? The monthly returns are [0.02, 0.015, -0.01, 0.03, 0.008, -0.005, 0.025] and the risk-free rate is 0.03.

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.002) API-based Sharpe ratio calculation without implementing the formula yourself. It is well-suited for agents automating financial analysis pipelines, backtesting workflows, or side-hustle investment comparisons where a pay-per-call model is preferable to hosting your own finance library.

## Known failure modes

- Empty or missing returns array — likely returns an error or undefined result
- Non-numeric values in the returns array — may cause a processing failure
- Standard deviation of zero (all returns identical) — causes division-by-zero, result may be undefined or infinite
- Missing risk_free parameter — may default to 0 or return an error
- Malformed JSON body — returns a 4xx error
- Insufficient funds (x402 payment failure) — returns 402 Payment Required
