KuCoin Data Parser & API

KuCoin is a global cryptocurrency exchange known for its early listings and deep altcoin coverage, and StockAPIS extracts its real-time market data — spot and futures prices, order book depth, OHLCV candles, trades and funding rates across 700+ trading pairs — through a single REST API. KuCoin offers an official public API, and StockAPIS normalizes it to the same schema you use for every other exchange, so you query KuCoin, Binance and Coinbase the same way without maintaining separate integrations.

Platform Overview

Market Position

• A top-10 crypto exchange by spot trading volume with a strong global retail base
• 700+ trading pairs, with some of the broadest early-listing altcoin coverage in the market
• Full product suite — spot, margin, perpetual futures, lending and built-in trading bots
• Official public REST + WebSocket API, complemented by StockAPIS’s unified normalization

Data Coverage

StockAPIS exposes the full KuCoin market surface:

• Spot market data — real-time prices, 24h volume, best bid/ask, size and price change
• Order book — level-2 depth snapshots, spreads and liquidity at configurable levels
• Trades — recent trade history with timestamps, side and size
• OHLCV / klines — candlestick data across intervals (1m → 1W) for historical and technical analysis
• Futures — perpetual contracts (e.g. XBTUSDTM), funding rates and open interest
• Margin — margin pairs, interest rates and lending data

Quick Start

import stockapis
 
client = stockapis.Client(api_key="your-api-key")
 
# Real-time ticker for a KuCoin pair
btc = client.kucoin.get_market_data(symbol="BTC-USDT")
print(f"Bitcoin: ${btc['price']}  ·  best bid {btc['bestBid']}")

const { StockAPIS } = require("stockapis");
const client = new StockAPIS({ apiKey: "your-api-key" });
 
// Live order book (level 2, top 100)
const book = await client.kucoin.getOrderBook({ symbol: "BTC-USDT", level: 2 });
console.log(book.bids[0], book.asks[0]);
