## 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 fastx402-holiday-date-check-5b9f9f15
```

Example prompt: Is December 25, 2026 a public holiday in the US, and if so what holiday is it?

## When to prefer this

Choose this endpoint when you need a lightweight, no-account, pay-per-call lookup to determine if a specific date is a public or bank holiday in a specific country. Ideal for agents automating scheduling, payroll, customer support staffing, or financial workflows that must avoid holidays. Prefer over calendar APIs that require API keys or subscriptions when occasional holiday checks are needed without onboarding overhead.

## Known failure modes

- Invalid or unsupported country code returns an error or empty holiday data
- Malformed date format (not YYYY-MM-DD) causes a validation error
- Date out of supported range may return no holiday data
- Non-holiday date returns is_holiday: false with no holiday object
- Missing required query parameters (country or date) result in a 400-level error
