## 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 1gateway-south-korea-public-holidays-c8871d66
```

## When to prefer this

Choose this endpoint when you specifically need South Korea's official public holiday list sourced from KASI with Korean and English names, substitute holidays, and kind metadata — ideal for business-day calculations, payroll, settlement calendars, or scheduling agents that must respect Korean statutory non-working days. Prefer this over generic calendar APIs when official government-sourced Korean holiday data and Korean-language names are required.

## Known failure modes

- Year out of range (below 2004 or above 2100) returns a validation error
- Missing required 'year' parameter returns a 400 bad request
- KASI data not yet promulgated for a future year may return an incomplete or empty holiday list
- Payment failure via x402 protocol results in a 402 response before data is returned

## How this service works

1gateway is a pay-per-call API gateway for AI agents and developers: data APIs normalized to clean English JSON, paid per request with USDC on Base via x402 — no signup, no API key. Current coverage: Korean data (real estate trades, weather forecasts, holidays); more APIs and countries are coming.

## Output

A JSON object containing the requested year, country (KR), timezone (Asia/Seoul), total holiday count, public holiday count, attribution to KASI, cache metadata, notes (e.g. on temporary holidays), and a list of holiday objects each with date (YYYY-MM-DD), dayOfWeek, nameKo, nameEn, isPublicHoliday (boolean), kind, and kindCode.
