# OpenHolidays Regional API — Public & School Holidays with Subdivision Granularity

> OpenHolidays Regional API — Public & School Holidays with Subdivision Granularity is a paid API for AI agents from x402-datashop-production.up.railway.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

## 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 openholidays-regional-api-public-school-holidays-with-subdivision-4bb29d17
```

Example prompt: What are the public holidays in Germany, specifically Bavaria (DE-BY), between July 1 and December 31, 2026?

## When to prefer this

Use this endpoint when you need subdivision-level holiday granularity (e.g. German Länder, French académies, Spanish autonomous communities) rather than just nationwide holidays. It is preferable to generic holiday APIs when regional differences matter — for scheduling, HR systems, travel planning, or compliance checks in federated countries. For simpler country-wide holiday lists without subdivision filtering, a lighter endpoint may suffice.

## Known failure modes

- Missing required 'country' parameter returns a 400 error
- Date window exceeding 366 days returns a validation error
- Unsupported or misspelled country code may return empty results or 404
- Invalid subdivision code may return empty results rather than an error
- Non-business or weekend dates are not relevant (holidays can fall any day, but ECB-style gaps don't apply here)
- Countries not covered by OpenHolidays (~36 mostly European) will return empty or error responses

## How this service works

Public holidays and school holidays with subdivision granularity (German Laender, French academies, Spanish communities...) from the OpenHolidays API (data ODbL-1.0, ~36 mostly European countries). Query: ?country=DE&from=2026-07-01&to=2026-12-31&type=public|school&subdivision=DE-BY (optional ISO 3166-2 filter; window max 366 days, default today +6 months). Each entry: dates, English name, nationwide flag, affected subdivision codes. 24h cache.

## Output

A list of holiday entries each containing: start and end dates, English holiday name, a boolean indicating whether the holiday is nationwide or region-specific, the holiday type (public or school), and the list of ISO 3166-2 subdivision codes affected. Results are cached for 24 hours.
