## 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 saylor-innovations-hourly-payroll-calculator-3053b904
```

Example prompt: Can you calculate my gross pay and estimated take-home for this pay period? I worked 46 hours at $21.50 an hour, and I want to apply a 22% withholding estimate.

## When to prefer this

Use this endpoint when you need a quick, structured hourly payroll breakdown including overtime splitting and optional withholding estimation — ideal for agents assisting hourly workers, small business owners, or HR tools that don't need full payroll system integration. Prefer this over salaried payroll calculators when the user bills or pays by the hour and works variable schedules.

## Known failure modes

- Missing required hourly_rate or hours parameters returns an error
- Negative hours or hourly_rate values are rejected as invalid
- Non-numeric string values for numeric fields cause parse errors
- Very large hour values may exceed expected range
- withholding_percent outside 0-100 range may produce unexpected results
