Cross-venue perp funding rate monitor API

Perpetual-futures funding rates for a crypto across multiple KEYLESS, US-reachable venues (dYdX v4, Hyperliquid, OKX, KuCoin), normalized to a common annualized basis (rate x periods/yr) since venues settle on different intervals (hourly vs 8h). Returns each venue's current + annualized rate, the cross-venue average, the max-min SPREAD (a funding-arb / fragmentation gauge), and a long/short-bias signal with a 0-100 conviction score: positive funding = longs pay shorts = crowded long. Geoblocked venues (Binance, Bybit) are omitted; failed venues are tolerated. Answers 'what is the BTC perp funding rate', 'are traders crowded long or short', 'cross-venue funding spread', 'annualized funding rate for ETH', 'is funding positive or negative'.
