About KuCoin

KuCoin's API documentation covers programmatic access to a cryptocurrency exchange, including market data (order books, klines, tickers, trades, funding rates, index prices), account management, and trading across spot, margin, and futures markets. It also documents sub-account management, deposits and withdrawals, and a WebSocket interface for real-time data such as order books, trades, positions, and balances.

The documentation includes sections for VIP lending, earn products (savings, staking, dual investment), an affiliate program, and multiple broker program tiers (Broker Pro, Exchange Broker) with their own API endpoints for sub-account creation, rebates, and KYC submission. Copy trading endpoints are also documented, covering order placement and take-profit/stop-loss configuration.

This resource is intended for developers building trading bots, exchange integrations, or brokerage/affiliate platforms on top of KuCoin's exchange infrastructure.
