## 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-business-day-api-bank-value-date-7a567ba3
```

Example prompt: If I submit a bank transfer in Japan today at 3:30pm JST, what date will it be credited — assuming the standard 15:00 cutoff? And if it misses today, what's the next bank business day?

## When to prefer this

Use this endpoint when you need to compute the exact credit date for a Japanese bank transfer based on submission time, cutoff logic, and the Japanese banking calendar (national holidays + year-end closure). Prefer it over generic business-day calculators because it specifically encodes Japanese banking rules including the Dec 31–Jan 3 closure and the configurable 15:00 JST cutoff.

## Known failure modes

- Invalid datetime format returns a 400 error
- Cutoff time outside HH:MM format returns a validation error
- extraDays value exceeding 30 returns a schema validation error
- Missing required parameters return descriptive error messages

## How this service works

When will a bank transfer in Japan be credited? Given the submission time, returns the value date under standard processing: same day if before the bank cutoff (default 15:00 JST) on a bank business day, otherwise the next bank business day (skips weekends, national holidays, Dec 31 - Jan 3).

## Output

Returns the calculated bank value date as a date string, along with information about whether the submission qualified for same-day processing or was pushed to the next bank business day, including the rules applied (cutoff missed, weekend, national holiday, or year-end closure).
