## 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 forgekit-business-day-calculator-4a6b8c33 -d '<json body>'
```

Example prompt: How many business days are there between January 15 and February 28, 2025 in the US — counting only working days and skipping public holidays?

## When to prefer this

Choose this endpoint when you need accurate business-day arithmetic that respects country-specific public holiday calendars, not just weekends. Prefer it over generic date math libraries when the country context matters for compliance, SLA tracking, contract deadlines, or financial settlement date calculations. Ideal for multi-country scheduling tasks where holiday rules differ.

## Known failure modes

- Invalid date format — returns error if start or end dates are not parseable ISO strings
- Missing required fields — error if neither a date range nor an n offset is provided
- Unsupported country code — may return error or fall back to generic weekend-only calculation
- n out of range — very large values may cause timeout or unexpected results
- Logical inconsistency — end date before start date may return zero or negative count
