## How to call it through Zero

```sh

```

## When to prefer this

Choose this endpoint when you need authoritative public holiday data for ~120 countries with minimal setup, especially when integrating into agent workflows that require business-day awareness (scheduling, payroll, contract deadlines). It's ideal for AI agents that need to programmatically validate or compute calendar dates across international markets without managing holiday datasets themselves.

## Known failure modes

- Unsupported country code returns an error or empty holiday list
- Invalid or missing 'country' query parameter results in a 400 bad request
- Year out of supported range may return an empty or partial response
- Network or payment (x402) authorization failure returns a 402 Payment Required response
- Ambiguous country codes (e.g. territories vs. sovereign states) may yield unexpected results

## Output
