## 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-market-calendar-api-daily-event-lookup-d5a53fa9
```

Example prompt: What Japanese market and macro events are happening on October 30, 2026 Japan time — specifically whether it's a BOJ decision day, a gotobi day, or has any tier-1 statistics releases like CPI?

## When to prefer this

Choose this endpoint when you need authoritative, source-linked Japanese market calendar data for a specific date, especially for automating trading decisions, scheduling macro-sensitive workflows, or building Japan-focused financial agents. It is purpose-built for AI agent consumption with structured flags and UTC times, unlike general financial data APIs that lack Japan-specific events like gotobi, SQ days, or MOF disclosures.

## Known failure modes

- Invalid date format (non-YYYY-MM-DD) may return an error or unexpected results
- Dates far in the future may have incomplete or unscheduled events
- No date parameter defaults to today in Japan (JST), which may be unexpected for callers in other timezones
- API returns empty events array for TSE holidays with tse_open: false
- Payment failure via x402 prevents access if USDC balance is insufficient

## How this service works

Machine-readable schedule of Japanese market and macro events for AI agents: Bank of Japan meetings, official statistics release times (CPI, GDP, Tankan, trade, wages...), JGB auctions, MOF portfolio flows and FX intervention disclosures, TSE holidays, SQ days, gotobi and month-end. Built from official Japanese government sources, with JST and UTC times and a source URL for every event. Pay per call with x402 (USDC on base).

## Output

Returns a JSON object with a structured list of events for the requested JST date, each containing an event ID, tier (1 = high-impact), event type (e.g. cpi_tokyo, boj_decision), JST and UTC datetimes, and an English title. Also includes a flags object summarizing key boolean market conditions (gotobi, sq_day, tse_open, month_end, jgb_auction, boj_decision_day, bank_business_day) and a count of tier-1 events for the day.
