CoinBoss is a crypto derivatives data platform for traders and analysts who need live market structure, not another price chart. It brings liquidations, open interest, funding rates, long-short ratios, spot and derivatives volume, ETF flows, stablecoin issuance, and exchange balances into one dashboard. Coverage spans major exchanges so crowded positions, funding extremes, and flow shifts are visible without switching tabs. The liquidations view shows 24-hour totals, liquidated trader counts, and a long versus short split over 1-hour, 4-hour, 12-hour, and 24-hour windows. Coin rankings include bitcoin and ether. Exchange rankings include Binance, OKX, Bybit, and Hyperliquid. A live liquidation stream and a liquidation heatmap show leverage flushes as they happen. CoinBoss fits crypto, fintech, and market-data work. A public free API is available, and the pricing page explains the free tier. It is not a trading venue and does not execute orders.
