How this service works
Resolve an address or ENS name and return ETH and USDC balances and tx counts on Ethereum and Base.
Output
Returns ETH balance, USDC balance, and transaction count for the given address or ENS name on both Ethereum mainnet and Base chain, giving a cross-chain financial snapshot of the wallet.
Example use cases
Pre-send recipient balance check
“Before I send funds to 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045, can you look up their current ETH and USDC balances and transaction history on Ethereum and Base?”
ENS wallet portfolio snapshot
“Resolve nick.eth for me and show me the ETH and USDC balances on both Ethereum mainnet and Base, plus the transaction counts.”
Due diligence on new counterparty
“I'm about to work with someone who gave me address 0xAbCd1234... — can you pull their wallet balances and transaction counts on Ethereum and Base so I can gauge how active they are?”
Technical details
Endpoint
GEThttps://x402-tools-production-2755.up.railway.app/tools/wallet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick multi-chain balance snapshot (ETH + USDC) across both Ethereum mainnet and Base for a single address or ENS name. It is ideal for pre-transaction due diligence, counterparty vetting, or portfolio checks where you need both chains in one call. Prefer this over generic blockchain explorers when you specifically need ETH and USDC balances plus tx counts on both Ethereum and Base simultaneously without additional API setup.
Side effects
- Invalid or malformed Ethereum address returns an error
- ENS name that cannot be resolved returns a resolution failure
- Unrecognized address format causes a validation error
- Rate limiting or upstream RPC node unavailability may cause timeouts
- Address with no activity returns zero balances and zero tx counts (valid but empty result)
