## 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 business-day-calculator-6ef8dea2
```

Example prompt: How many business days are there between December 1 and December 31, 2026 in the US, excluding weekends and public holidays?

## When to prefer this

Choose this endpoint when you need accurate business day counts that account for both weekends and country-specific public holidays, rather than a simple weekday counter. Ideal for SLA enforcement, invoice due date computation, legal deadline verification, and shipping scheduling where national holidays vary by country. Prefer this over generic date math when the country context matters and holiday-aware accuracy is required.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) causes a 400 bad request
- Invalid or unsupported ISO country code returns an error or ignores holiday data
- End date before start date may return zero or negative business days
- Missing required start or end parameters causes a 400 validation error
- Country code not recognized may default to no holiday exclusions
