Funding Rate Arbitrage Scanner API

br0ski777/funding-arb-x402

Connects Claude to real-time perpetual futures funding rates across Hyperliquid, Binance, Bybit, and OKX to spot arbitrage opportunities. Built for crypto trading agents that need to monitor cross-venue spreads and execute funding rate strategies. The server exposes data through a remote API at funding-arb.api.klymax402.com, letting you query current rates and spreads without running your own exchange integrations. Useful when you're building automated strategies that profit from funding rate differentials or need to monitor positions across multiple venues. The x402 designation suggests this is part of a specific trading system or fund identifier.
