Pulls real-time crypto wallet data across Base and Ethereum chains, surfacing native balances, ERC-20 token holdings, and USD valuations through a straightforward MCP interface. Built on the x402 micropayment protocol, so queries cost fractions of a cent in USDC rather than running on API keys or subscription tiers. Reach for this when you're building agents that need portfolio snapshots, balance checks, or multi-chain asset tracking without maintaining your own node infrastructure. The SSE transport keeps connections open for streaming updates. Lightweight enough for quick wallet queries, specific enough that you're not wading through a general-purpose blockchain API to get basic portfolio data.
