## 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 worldwide-holidays-lookup-api-8bc4cb5e
```

Example prompt: What are all the public holidays in Germany, specifically in Bavaria (BY), for the year 2026?

## When to prefer this

Choose this endpoint when you need structured, machine-readable holiday data for 200+ countries with optional subdivision granularity, holiday type filtering, and pay-per-call USDC pricing via x402 (no API key required). Prefer it over calendar libraries when you need authoritative, up-to-date data at runtime without bundling a local dataset.

## Known failure modes

- Invalid or unsupported country code returns an error
- Year outside 1900-2100 range is rejected by schema validation
- Unknown region/subdivision code may return empty or error
- Payment failure (x402) if USDC balance is insufficient
- Network timeout if the Render.com service is cold-starting

## How this service works

Calendar and Japan data APIs for AI agents: worldwide holidays and business days (200+ countries), plus Japanese text-to-structure (address, name, bank, company normalization). Pay per call in USDC via x402, no API key.

## Output

Returns a JSON object with the year, country code, optional region, total holiday count, data source attribution, and an array of holiday objects each containing the date (YYYY-MM-DD), English name, local-language name, holiday type (public/bank/school/optional/observance), and a substitute-day flag.
