## 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 japan-public-holidays-api-527e16c5
```

Example prompt: What are all the official Japanese public holidays for 2026? I need the full list with dates and names.

## When to prefer this

Choose this endpoint when you need official, government-sourced Japanese public holiday data for a specific year, especially in contexts requiring accuracy for business scheduling, payroll, or compliance. It is the right choice for year-level holiday lookups covering the full official Japanese calendar. Prefer it over generic calendar APIs when you need Japanese-language holiday names and official government provenance.

## Known failure modes

- Year out of range (below 1955 or above 2100) returns a validation error
- Missing required 'year' query parameter returns an error
- Payment not provided or insufficient USDC balance returns HTTP 402
- Upstream Cabinet Office data unavailable causes server error
- Non-integer year value rejected by schema validation

## 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

A JSON object containing the requested year, total count of holidays, a source citation (Cabinet Office of Japan URL), and an array of holiday objects each with a date (YYYY-MM-DD) and Japanese name.
