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.
Example use cases
BOJ meeting day trade pre-check
“Is October 30, 2026 a Bank of Japan policy decision day, and are there any other major macro events that day that could move markets?”
Gotobi and month-end FX flow alert
“I'm watching USD/JPY flows — can you check if today in Japan is a gotobi day or month-end, since those tend to drive corporate FX demand?”
Japanese data release scheduling for algo
“What tier-1 Japanese statistics — like CPI, GDP, or Tankan — are being released on 2026-10-30, and what time do they come out in both JST and UTC?”
Technical details
Endpoint
GEThttps://japan-market-calendar.after6labo.workers.dev/v1/day?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
