GET /api/v1/perps/predicted-funding

live

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).

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).
