## 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 opendata402-dutch-school-holidays-439d3bbc
```

Example prompt: Can you look up the official Dutch school holidays for the 2025-2026 school year, including all regions — north, middle, and south — so I can see the autumn, Christmas, spring, May, and summer break dates?

## When to prefer this

Choose this endpoint when you need authoritative, government-sourced Dutch school holiday dates broken down by region and school year. It is ideal for travel pricing, staffing, scheduling, or calendar enrichment applications that depend on official Rijksoverheid data rather than crowd-sourced or third-party holiday databases.

## Known failure modes

- Invalid school year format (must match ^\d{4}-\d{4}$) returns a validation error
- Requesting a school year not yet published returns an empty result or 404
- Network or payment failure returns an HTTP error with no holiday data
- Unsupported query parameters may be silently ignored

## How this service works

Official Dutch school holiday dates per school year and region (north, middle, south) from the Dutch central government: autumn, Christmas, spring, May and summer holidays with start and end dates. Use it for travel, staffing, pricing or scheduling around Dutch school breaks.

## Output

A structured list of Dutch school holidays for the requested school year(s), each entry containing the holiday name (e.g. autumn holiday, Christmas holiday, summer holiday), start date, end date, and the applicable region (north, middle, south). If no school year is specified, all published years are returned.
