About the project

Welcome to J-Quants API

The Japan Exchange Group launched J-Quants as a proof-of-concept project to provide data and environment related to investment and to verify the possibility of data utilization by individual investors.

J-Quants is implementing various measures, including the provision of learning-based contents, with the purpose of enabling individual investors to trade using data. As part of this project, we decided to provide this J-Quants API (beta version) considering that we received favorable reviews about APIs we offered in the stock data analysis competition held last year.

The data and API methods provided by this API are under demonstration. Specifications may change after launch of this service.

About Beta Version

Since this API is a proof-of-concept project, firstly we released it to the public free of charge as a beta version and aim to improve and correct it with feedback.
