## How to call it through Zero

```sh
zero fetch --capability gotobi-hugen-tokyo-0f867dbf
```

Example prompt: Is today a gotobi day in Japan? I need to know if there will be predictable USDJPY buying pressure at the 9:55 JST Nakane fixing today.

## When to prefer this

Use this endpoint when you need a real-time, programmatic check of whether today is a Japanese gotobi day (5th, 10th, 15th, 20th, 25th, or last business day of the month), with automatic adjustments for Japanese public holidays and weekends. This is described as the only programmatic source for gotobi dates. Prefer this over manual date arithmetic, which won't correctly handle holiday roll-forward rules.

## Known failure modes

- Service unavailable — no response from endpoint
- Payment failure — insufficient USDC balance for x402 micropayment
- Timezone edge cases around JST midnight may return unexpected dates

## How this service works

Is today a Japanese gotobi day? Gotobi (五十日: 5th, 10th, 15th, 20th, 25th, last business day) drive predictable USDJPY buying pressure before the 9:55 JST Nakane fixing. Weekend and holiday adjustments applied automatically. No public database of gotobi dates exists — this is the only programmatic source. Accepts USDC payments on Base and Solana

## Output

Returns a JSON object with today's date (JST), a boolean is_gotobi field indicating whether today is a gotobi day (with weekend and public holiday adjustments applied), and a human-readable English description of the result.
