2026/07/22 18:18:00
Siebly’s JavaScript SDK streamlines access to KuCoin REST APIs and WebSocket services for developers.
KuCoin is pleased to announce expanded JavaScript SDK support through a technical collaboration with Siebly, giving developers a more streamlined way to build applications connected to KuCoin’s API ecosystem.
As algorithmic trading and automated applications continue to evolve, developers need reliable, production-ready tools that simplify API integration while maintaining flexibility and performance. Through this collaboration, Siebly now provides official JavaScript SDKs covering both KuCoin Unified Trading API (UTA) and Classic APIs, enabling developers to build trading applications more efficiently with less implementation effort.
Designed for Modern Trading Applications
The official JavaScript SDKs provide a streamlined interface for interacting with KuCoin's REST/Websocket APIs while remaining fully compatible with the latest platform capabilities.
The SDKs support:
-
Unified Trading API (UTA) for next-generation account architecture.
-
Classic Spot, Margin, and Futures APIs for existing integrations.
-
Secure API authentication and automatic request signing.
-
Standardized request and response handling.
-
Consistent error management and retry-friendly design.
-
Modular architecture for rapid integration into existing applications.
-
Ongoing updates to ensure compatibility with newly released KuCoin API features.
Whether you're developing a high-frequency trading bot, institutional execution engine, broker platform, quantitative trading system, portfolio management application, or Web3 trading product, the SDKs provide a robust foundation for production deployment.
Built for Developer Productivity
The JavaScript SDK handles common authentication, request signing, response handling and endpoint mapping, helping developers spend less time on repetitive integration work and more time building product-specific features and trading workflows.
For both new and established projects, the additional tooling offers a flexible way to access KuCoin’s API capabilities. Developers retain control over implementation and testing, while the SDK can help shorten the path from initial setup to application development.
