## 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-holiday-business-day-api-next-business-day-f94029d0 -d '<json body>'
```

Example prompt: What is the next business day in Japan starting from May 2, 2026? I need to know when the next working day falls after that date, skipping any public holidays or weekends.

## When to prefer this

Choose this endpoint when you need to calculate the next business day specifically within the Japanese calendar, accounting for Japan's official public holidays from 1955 to 2027. Prefer this over generic business-day calculators when Japan-specific holidays (such as Golden Week, Obon, or national holidays) must be respected. Especially useful for fintech, settlement, and scheduling workflows targeting Japan.

## Known failure modes

- Date outside supported range (1955-2027) returns an error
- Malformed date format causes a 400-level error
- Network or upstream service unavailability
- Payment failure via x402 prevents request from being processed

## How this service works
