## 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-ebc8c408 -d '<json body>'
```

Example prompt: Calculate the Sharpe ratio for these monthly returns: [0.02, 0.015, -0.01, 0.03, 0.025, 0.01, -0.005, 0.02] with a risk-free rate of 0.004.

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.002 per call) computation of the Sharpe ratio for any list of numeric returns and a risk-free rate. Prefer this for lightweight portfolio analytics pipelines, automated strategy evaluation, or when integrating risk-adjusted performance metrics into an agent workflow without standing up your own financial computation service.

## Known failure modes

- Missing or empty returns array — endpoint may return error or unexpected result
- Non-numeric values in the returns array causing computation failure
- Risk-free rate not provided — may default or error depending on implementation
- Standard deviation of returns is zero (all identical returns) — causes division-by-zero in Sharpe ratio formula
- Malformed JSON body — returns 400 or similar error
- Response schema is minimal and may not return the numeric Sharpe ratio directly, only a generic 'processed' status
