KuCoin API Node.js, JavaScript & TypeScript SDK by Siebly

KuCoin integration resources, package links, and quick start guides.

Coverage Summary

KuCoin Node.js/TypeScript SDKs for spot, margin, futures, and lending integrations.

Who This SDK Is For

The KuCoin Node.js, JavaScript & TypeScript SDKs are built for teams & individual software developers that need reliable Spot, Margin, Futures, Lending, WebSockets integrations in production systems.

Each language-specific guide below shows how to use the same KuCoin SDK package in that environment, with runnable examples linked for scenario-specific workflows.

KuCoin REST API Scope

Use the KuCoin SDK for spot, margin, futures, lending, account, order, balance, and market data workflows that need exchange-specific REST coverage.

KuCoin WebSocket Scope

Use WebSocket clients for KuCoin market and private streaming workflows, including exchange-managed WebSocket session setup where required.

Authentication, Rate Limits & Reliability

Treat WebSocket token/session renewal, symbol formats, and product-specific clients as explicit integration steps; stage changes against low-risk credentials first.

Supported Feature Areas

  • Spot
  • Margin
  • Futures
  • Lending
  • WebSockets

Common Integration Workflows

  • Build authenticated KuCoin REST API workflows for account state, balances, and order execution.
  • Stream KuCoin market and account events over WebSocket with reconnect-aware handling.
  • Deploy typed Node.js services with explicit request/response models and predictable error handling.

Implementation Guidance

  • Never store API keys in source files. Follow best practices for protecting API keys and secrets, as you would a password.
  • Start in testnet or low-risk modes before routing automation to production account credentials.
  • To consume WebSocket events, use the exported WebsocketClient from each SDK. Be sure to use the event handlers (message or update, depending on SDK) to handle incoming events after subscribing.
  • For REST API calls, use the provided REST client classes and methods to ensure proper signing, authentication, and error handling. These classes are exported by every SDK and provide fully typed functions wrapped around individual API endpoints. Refer to the quick start guides for code snippets and patterns.
  • Track package updates and changelog entries through the release feed before upgrading live systems.
  • Validate leverage, margin, and liquidation-sensitive request paths carefully for KuCoin derivatives workflows.
