Example prompt: What's the current SOL funding rate arbitrage spread across Binance, OKX, Bybit, KuCoin, Bitget, and Hyperliquid — give me the gross and net-of-fees spread in bps and tell me whether it's actionable?

## When to prefer this

Use this endpoint when you specifically need cross-venue funding rate arbitrage signals for SOL across the six major perpetual futures venues (Binance, OKX, Bybit, KuCoin, Bitget, Hyperliquid). It is ideal for delta-neutral funding arb strategies, real-time screening for actionable spreads, and automated trading signals. Prefer it over generic funding rate feeds when you need net-of-fees spread calculations and a ready-made actionability label rather than raw rates you'd have to compare yourself.

## Known failure modes

- Payment not processed – x402 payment of $0.02 USDC required before data is returned
- Venue data unavailable – one or more exchanges may have delayed or missing funding rate data
- Asset not covered – this endpoint is specific to SOL; other assets use different paths
- Rate limiting – repeated calls in short succession may be throttled
- Stale data – funding rates are real-time but upstream venue APIs may lag
