Japan's First! US Stock API Now Supports "Margin Trading"

Webull Securities Co., Ltd. (Location: Chuo-ku, Tokyo, Representative Director: Kazumi Kojima), the Japanese base of US-based Webull Corporation (NASDAQ: BULL), a major digital investment platform, is pleased to announce that it will newly offer a US stock margin trading function through its "Webull Open API".

Until now, only spot trading of US and Japanese stocks was supported via API, but with this new function, US stock margin trading will become possible.

According to our research (as of March 2026), Webull Securities is the first in Japan among major domestic online securities firms (SBI Securities, Rakuten Securities, Monex Securities, Matsui Securities, Mitsubishi UFJ e Smart Securities) to offer US stock margin trading via API.

With the provision of this function, investors and developers will be able to build a more advanced and flexible US stock trading environment.

Expanding Possibilities for US Stock Trading with Webull Open API

Webull Open API is an API service that allows users to utilize stock trading functions from environments other than the Webull app.

In addition to the previously offered spot trading of US and Japanese stocks, the new support for US stock margin trading enables a wider range of investment strategies, such as leveraged trading and short selling, to be executed via API.

This will provide an environment that meets the diverse needs of investors, including algorithmic trading, automated trading, and trading with proprietary tools.
