This server connects Claude to real-time DeFi data through pay-per-call micropayments using USDC on Base. It exposes eight tools including crypto price feeds, multi-chain gas tracking, DEX swap quotes from Uniswap and 1inch, token security scanning with rug-pull detection, whale tracking, yield opportunities across Aave and Compound, perpetual funding rates, and full wallet profiling. Each call costs between 0.001 and 0.008 USDC and uses the x402 protocol for HTTP 402 payment flow. You can run it in inspect mode to see payment requirements manually or set a wallet private key for fully autonomous operation where the agent pays for its own data requests.
