## How to call it through Zero

## When to prefer this

Use this endpoint when you need the complete set of all 6 gotobi dates for an entire month, especially when you need to plan ahead or analyze USDJPY pressure patterns across a full month. Prefer this over the 'next gotobi' or 'is today gotobi' endpoints when building calendars, scheduling tools, or performing multi-date analysis for a given month.

## Known failure modes

- Invalid month format returns an error — must be YYYY-MM
- Month out of supported range (beyond 2099) may return an error or unsupported response
- Missing month parameter may result in a bad request error
- Payment failure (402) if USDC payment on Base or Solana is not provided or insufficient

## How this service works

Monthly gotobi calendar with all 6 dates (5th, 10th, 15th, 20th, 25th, last business day) and automatic weekend/holiday adjustments. No public database of adjusted gotobi dates exists — building one requires Japanese holiday law knowledge through 2099. Accepts USDC payments on Base and Solana

## Output

A JSON object containing the year, month, count of gotobi days (always 6), a description noting the USDJPY fixing pressure context, and an array of ISO date strings for each adjusted gotobi date in the requested month.
