Binance Spot WebSocket Market Streams

Binance Spot WebSocket Market Streams is a websocket from Binance providing crypto data. Binance's public WebSocket market data streams push real-time spot trades, klines (OHLCV candles), 24h tickers, best bid/ask and order-book depth for BTC/ETH and hundreds of altcoin pairs. As the deepest-liquidity spot venue, it serves as the de-facto reference price for Polymarket "will BTC/ETH close above $X" hourly and daily markets, letting a bot track the underlying live and anticipate market resolution.
