Summary
Pulls real-time and historical funding rates for all 229 Hyperliquid perpetual markets through three x402-gated endpoints. You can sort current rates by absolute value to spot extremes, fetch hourly history for specific coins with summary stats, or scan for arbitrage opportunities above a funding threshold. Each call costs $0.002 to $0.003 in USDC on Base. Useful for carry trade hunting, delta-neutral strategies, or comparing HL funding against other exchanges to find cross-venue spreads. Responses include annualized rates, open interest, and mark prices. Payment happens automatically through x402, so no API keys or subscriptions.
