Use J-Quants from your AI
Fetch Japanese stock market data from J-Quants (JPX official API): listed company master, daily OHLC prices, quarterly financial summaries, earnings announcement schedules, and the trading calendar. Requires a J-Quants API key (free plan available).
This server connects your AI client to J-Quants API V2, the official market data API operated by JPX Market Innovation & Research (Japan Exchange Group). It provides pro-grade Japanese equities data collected directly from the exchange.
Key features:
- Look up listed companies (name, sector, market segment) by issue code or by company-name keyword.
- Fetch daily OHLC bars (open/high/low/close, volume, turnover, and split-adjusted figures) for any listed stock, over a date range.
- Fetch quarterly financial summaries built from TDnet earnings reports (kessan tanshin).
- Check upcoming earnings announcement dates and the trading calendar (market holidays).
Using the API requires a J-Quants account and an API key issued from the J-Quants dashboard. A free plan is available (data is delayed; paid plans unlock fresher data, longer history, and higher rate limits - the free plan allows 5 requests per minute). Set the key as JQUANTS_API_KEY in your Arlet environment variables.
What you need
- An Arlet account
- An API key issued by J-Quants is required (most are free to obtain).
