Perps Funding Forecast

Predicted next-period funding rate for each coin across venues — on-chain plus centralized perp venues (Hyperliquid, Binance, Bybit) — each with the funding interval and next funding time. A cross-exchange funding-arbitrage signal in one call: compare where a coin's funding is richest or cheapest. Free on-chain DEX data, no key. From x402stock, a market & economic data API (x402, USDC).
