## 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-public-holidays-nl-be-de-3d2e3a7c
```

Example prompt: What are all the public holidays in Germany for 2025? I need the dates and names in both English and German so I can block them out of our delivery schedule.

## When to prefer this

Use this endpoint when you need authoritative, computed statutory holiday data for the Netherlands, Belgium, or Germany across any year from 1900 to 2200 — especially for scheduling, delivery date calculation, payment terms, or staffing planning. It covers all three countries from a single endpoint and handles edge cases like Easter-derived holidays automatically.

## Known failure modes

- Invalid country code (not NL, BE, or DE) returns an error
- Year outside the 1900–2200 range returns a validation error
- Missing required query parameters (country or year) returns a 400-style error
- Network or upstream service failure may return a 5xx error

## How this service works

Public holidays for the Netherlands, Belgium and Germany (nationwide) for any year 1900-2200, computed from the statutory rules and the Easter date: date, English and local name, with notes where a day is commonly worked. Use it for scheduling, delivery dates, payment terms and staffing in the Benelux and Germany.

## Output

A structured list of public holidays for the requested country and year, each entry containing the date, the holiday name in English, the local-language name, and any notes about whether the day is commonly worked despite being a statutory holiday.
