Perpetual Funding Rates API

br0ski777/funding-rates-x402

Pulls perpetual futures funding rates from Binance, Bybit, and OKX through a single MCP interface hosted at funding-rates.api.klymax402.com. You get live funding rates, open interest data, and market sentiment indicators across major crypto derivatives exchanges. Useful when you're building trading bots, monitoring cross-exchange arbitrage opportunities, or tracking whale positioning through funding rate divergence. The server uses SSE transport and appears to be part of the x402 ecosystem. If you're working with crypto derivatives data and want a unified view without managing three separate exchange APIs, this consolidates the signal into one stream.
