Cross-venue funding arbitrage signal — up to 6 exchanges, net-of-fees — $0.02/call

Queries up to 6 perpetual swap exchanges for real-time 8h-equivalent funding rates (Binance USDT-M, OKX, Bybit, KuCoin Futures, Bitget, Hyperliquid) and computes the gross and net-of-fees spread between the best short venue (highest rate8h) and the best long venue (lowest rate8h). gross_spread_bps = (best_short_rate8h − best_long_rate8h) × 10000. net_spread_bps = gross_spread_bps − 20 (ROUND_TRIP_FEE_BPS: 5 bps/side taker × 4 fills). annualized_pct = (net per-8h fraction) × 3 × 365 × 100. Actionability: not_actionable (net≤0), marginal (0<net≤5 bps), actionable (net>5 bps). Outcome recorded to Supabase funding_arb_signals (fire-and-forget). Returns honest nulls when a venue fails — never fabricated. All 17 assets. $0.02 USDC via x402.
