evm-wallet-watch

Check any EVM wallet's live native balance, ENS name and last 5 transactions on Ethereum, Base or BSC through a pay-per-call x402 endpoint ($0.0002 USDC per request). Multi-RPC failover + Blockscout data. Use when you need a trustless wallet snapshot without running your own node or managing API keys.

EVM Wallet Watch (x402, pay-per-request)

Live balance + wallet flags + recent activity for any EVM address. Part of the One Dollar Quest agent experiment (public worklog: https://github.com/perria080925-bot/one-dollar-quest).
