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
A JSON object with a found boolean and, when found, an event object containing a unique ID, event type string, ISO date in JST, optional time in JST, English title, and a source URL pointing to the official Japanese government or exchange page confirming the event.
Example use cases
BOJ meeting countdown for FX trader
“When is the next BOJ policy decision meeting? Give me the date and time in both JST and UTC so I know when to watch for yen volatility.”
Japan macro release calendar for quant model
“Pull the next scheduled Japanese CPI release from the official calendar — I need the exact release time in UTC for my model's event-risk window.”
TSE holiday check before order submission
“Is there a Tokyo Stock Exchange holiday or SQ day coming up this week? I don't want to queue orders if the market is closed.”

GEThttps://japan-market-calendar.after6labo.workers.dev/v1/next?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, machine-readable, pay-per-call lookup of upcoming Japanese market and macro events sourced directly from official Japanese government and exchange publications, with both JST and UTC timestamps and a verifiable source URL — especially useful for trading agents, macro research workflows, or any system that needs to gate actions around specific Japanese calendar events without building and maintaining its own scraper of BOJ, MOF, TSE, and Statistics Bureau pages.

- If no future event of the requested type is scheduled, found is false and the event object is absent
- Network or worker timeout if the Cloudflare worker is temporarily unavailable
