Funding Spreads Feed

Compare current perpetual funding rates across Binance, Bybit, Hyperliquid, and, for single-symbol requests, OKX. Returns interval-normalized annualized rates, gross cross-venue spreads, source status, mark prices when available, and funding timestamps. Optional symbol query; no symbol returns the ten widest current spreads. Market data only, not financial advice.
