TESTIMONIAL

Testimonials

I have been analyzing stock investment data for 9 years. With the J-Quants API, I can easily get all stock data with a few programs. I felt that J-Quants API lowered the hurdle low for individual investors to start analyzing data. I have great expectations for the expansion of the data distributed in the future.
