## 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 toolsmith-holidays-business-day-api-6d473401
```

Example prompt: Can you tell me all the public holidays in Germany for 2025, and also check whether December 26, 2025 is a business day?

## When to prefer this

Use this endpoint when you need authoritative public holiday data for any of 100+ countries, especially when combined with business-day validation logic. Prefer this over calendar libraries when you need a live, maintained, multi-country dataset without managing holiday data yourself. Ideal for scheduling, payroll, contract deadline, and compliance use cases.

## Known failure modes

- Missing required country parameter returns an error
- Invalid ISO country code returns an error or empty holidays list
- Unsupported country (not among 100+ covered) may return empty or error
- Invalid date format (not YYYY-MM-DD) for optional date parameter causes error
- Invalid year value may return error

## How this service works

Public holidays for any country and year, plus optional business-day checking. Pass country= (ISO alpha-2) and year=; add date= to learn whether that day is a business day, whether it is a weekend or public holiday, the holiday name, and the next business day. Covers 100+ countries. JSON response. $0.01 USDC per call, pay via x402, no API key.

## Output

A JSON object listing all public holidays for the requested country and year, each with date and holiday name. If a date query parameter is provided, the response also includes whether that date is a business day, whether it falls on a weekend or public holiday, the name of the holiday (if any), and the next business day.
