• Sequence-number-based gap detection
• Spot and KuCoin Futures support

Trading pairs: 800+ trading pairs with deep altcoin coverage

Protocol: WebSocket with /market/level2 topic subscriptions and token auth

Quick Start — KuCoin via WebSocket

Connect to our unified API and subscribe to KuCoin data with three lines of code:

// Connect to Microverse Systems API
const ws = new WebSocket("wss://api.microversesystems.com");

// Subscribe to KuCoin BTC order book
ws.send(JSON.stringify({
  "op": "subscribe",
  "channel": "kucoin:BTC-USDT",
  "depth": 20
}));

// Receive real-time L2 updates
ws.onmessage = (e) => {
  const book = JSON.parse(e.data);
  console.log(book.bids[0], book.asks[0]); // best bid/ask
};
