Introduction

TradeUP OpenAPI Platform provides API services for individual developers and institutional clients. To facilitate user access, we have developed the OpenAPI SDK. The OpenAPI SDK encapsulates TradeUP's underlying interfaces, allowing trading programs written in a user-selected programming language (currently supporting Java/Python/C++/C#) to conveniently call OpenAPI interfaces to use TradeUP's market data, trading, and push services. Currently, the TradeUP API supports operations on all account types, including Live and Paper Trading accounts.
