Japan's equity markets — the Tokyo Stock Exchange and Osaka Exchange, collectively the Japan Exchange Group (JPX) — are the world's third-largest by market capitalisation. Until now, accessing structured JPX market data meant paying for a data-vendor subscription or scraping the official JPX website, which publishes its statistics as HTML tables and PDF downloads. The JPX API changes that.
Today we're launching the JPX API — 13 dedicated endpoints covering Japan's equity markets, accessible through the same Anysite API and credit-based pricing as every other endpoint in the catalog.
What the JPX API covers
The endpoints are organised into four families:
Equities (7 endpoints)
The equities family covers the day-to-day data institutional and quantitative traders need: upcoming ex-dividend events, ex-rights and ex-dividend detachments from the most recent trading day, securities under current trading suspension, weekly and monthly index return data, margin trading outstanding balances, segment-level market statistics (Prime, Standard, Growth), and top stocks by turnover — the day's most active names by segment.
Indices (1 endpoint)
Current price data for JPX market indices: TOPIX, Nikkei 225, and the segment sub-indices. Index name, current level, change, and percentage change — in one call.
Listings (4 endpoints)
The listings family covers the universe of what's listed: TOPIX constituent stocks with their TSE 33-sector classification and component weights (the foundation of any Japan index-replication or factor model), monthly investment trust and ETF quotation listings, REIT trading statistics, and listed company counts by market segment.
Statistics (1 endpoint)
Weekly investor-type trading statistics: the breakdown of buy and sell volumes by investor category — foreign investors, domestic institutions, retail investors, and proprietary trading desks. This is the most-watched weekly data release for anyone following Japan equity market flows. It distinguishes whether a Japan rally is foreign-driven or domestically-led — a distinction that matters for macro positioning.
What you can build
A few concrete use cases:
Market monitoring dashboards. Pull index levels, top movers by turnover, and segment stats in three calls at market open. Build the Japan equity dashboard you couldn't afford before.
Corporate actions pipelines. Check upcoming ex-dividend dates and same-day rights detachments programmatically — a feed that event-driven strategies, portfolio managers, and compliance teams all need, and that previously required a dedicated data vendor.
Index replication and factor models. The TOPIX constituents endpoint returns the full list of constituent stocks with sector weights. Combine it with the margin balance and investor-type data for a quantitative signal stack covering Japan.
ETF and REIT screening. The full JPX ETF and REIT listing universe — fund name, ticker, NAV, market metrics — available as JSON for the first time.
JPX API pricing and access
All 13 JPX endpoints cost 1 credit per request — the same as most endpoints in the catalog. The Starter plan at $49/mo includes 15,000 credits, which is more than enough for comprehensive daily JPX coverage.
