How this service works
Cross-venue funding arbitrage signal from real-time 8h-equivalent funding rates on Binance, OKX, Bybit, KuCoin, Bitget and Hyperliquid. Returns the gross and net-of-fees spread between the best short venue and best long venue (gross_spread_bps, net_spread_bps after a 20 bps round-trip fee estimate), spread_8h_normalized, venues_count, per-venue rates with funding_interval_hours, annualized_pct, and an actionability label. All 16 assets. $0.003 USDC via x402.
Output
Returns gross_spread_bps (raw funding rate spread), net_spread_bps (after ~20 bps round-trip fee estimate), annualized_pct (annualized return of the arb), an actionability label indicating whether the opportunity is worth pursuing, and per-venue 8h-equivalent funding rates for Binance, OKX, Bybit, KuCoin, Bitget, and Hyperliquid. Signal is also recorded to Supabase asynchronously.
