MCP Server x402 License: MIT

Funding rate arbitrage scanner -- Hyperliquid, Binance, Bybit, OKX cross-venue spreads and annualized yields. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

{
  "mcpServers": {
    "funding-arb": {
      "url": "https://funding-arb.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

curl "https://funding-arb.api.klymax402.com/api/scan"
# -> 402 Payment Required, with an x402 payment challenge in the response body
