## How to call it through Zero

```sh
zero fetch --capability gotobi-hugen-tokyo-0b68100b
```

Example prompt: What is the next gotobi day coming up, with any Japanese public holiday or weekend adjustments applied, so I can time my USDJPY position before the Tokyo fixing?

## When to prefer this

Use this endpoint when you need a single, authoritative, holiday-adjusted next gotobi date for FX trading timing decisions — especially for USDJPY pre-positioning before the 9:55 JST Nakane fixing. No public gotobi calendar exists, making this the only programmatic source with automatic Japanese holiday and weekend shift adjustments.

## Known failure modes

- Service unavailable or timeout if the payment fails via x402
- Incorrect date if JST timezone is not handled server-side
- Edge cases around year-end last business day calculation may yield unexpected results

## How this service works

Next upcoming gotobi day with countdown — returns the exact date with Japanese public holiday adjustments applied. Essential for pre-positioning USDJPY trades ahead of the Tokyo fixing. No public gotobi calendar exists; building one requires Japanese holiday law + weekend shift rules. Accepts USDC payments on Base and Solana

## Output

Returns the exact date of the next upcoming gotobi day (5th, 10th, 15th, 20th, 25th, or last business day of the month), adjusted for Japanese public holidays and weekend shift rules, along with a countdown in days from the current JST date.
