Jul. 04, 2022 JPXI General Launch of API Distribution Service "J-Quants API" (Beta) for Retail Investors

 

JPXI provides an environment to promote trading utilizing IT and data analysis for individuals interested in data science via the "J-Quants" project.

As part of this project, from April to the end of May, JPXI provided the J-Quants API (beta) service (hereinafter "the Service"), which distributes historical stock prices and corporate financial data through API, to limited users (Early Adopters) chosen by lottery. JPXI has now decided to start providing the Service to general users from Monday, July 4.

J-Quants API

The current environment in Japan does not allow easy access for retail investors to obtain and use raw financial data. To tackle this, last year, JPX Group launched an environment through the J-Quants project which enabled retail investors to learn about investment analysis utilizing data, by providing financial data that professionals use such as historical stock prices and corporate financial data together with analytical methods for these data. Following its provision of financial data through API as part of this initiative, such as stock price and corporate financial data, we received many requests for this to be continued. Accordingly, JPX decided to launch this service as a beta version.

The following data will be distributed though API. This will allow comparisons among listed companies and chronological stock price analysis from the user's preferred perspective.

  • Historical stock price data of listed companies on the Tokyo Stock Exchange (stock prices adjusted for stock splits, etc. (opening/high/low/closing prices) and trading volume, etc. from 2017)
  • Corporate financial data taken from earnings reports (summary information of quarterly earnings reports from 2017)
  • Issue information
  • Industrial sector information
  • Planned financial results announcements for the next day

JPXI will improve the convenience of the Service, incorporating feedback from users during the beta service period, and aims for it to be a sustainable paid service. We offer registered users a Slack Workspace to exchange views. We hope that users will provide us with proactive feedback.

For the Early Adopter service until May, access was provided using NFTs, but after today's general launch, the service will be accessible with a user registration only and NFTs will not be used.
