agentpay.tools/tools/funding_spread/call

Cross-venue perp funding divergence for one asset: per-venue funding normalised to 8h across Binance, Bybit, OKX, Gate.io, Bitget, Hyperliquid, dYdX, MEXC and KuCoin, the spread (max-min, cheapest and dearest venue), its 7-day percentile, and a carry estimate for a given notional net of taker fees. The basis/carry arbitrage read, not the raw rates.
