How this service works
Base wallet snapshot: Basename, account type (EOA, contract, EIP-7702 delegated), tx count and activity level, ETH balance and balances of 31 major Base tokens (USDC, USDT, WETH, cbBTC, wstETH, AERO, VIRTUAL, DEGEN, BRETT...) with USD values and total, plus a one-line summary. Query: address.
Output
Returns a structured JSON object containing: the address's Basename (if registered), account type (EOA, contract, or EIP-7702 delegated), total transaction count and activity level label, ETH balance, individual balances for 31 major Base tokens (USDC, USDT, WETH, cbBTC, wstETH, AERO, VIRTUAL, DEGEN, BRETT, and others) each with USD value, a grand total portfolio value in USD, and a concise one-line human-readable summary of the wallet.
Example use cases
Due diligence on counterparty wallet
“Before I send funds to 0xAbCd1234567890abcdef1234567890abcdef5678, can you check their Base wallet snapshot — what tokens they hold, total portfolio value, whether it's a real active wallet or a fresh address, and what account type it is?”
Portfolio check for DeFi tracking
“Give me a full breakdown of my Base wallet 0xDeAdBeEf1234567890abcdef1234567890aBcDeF — all token balances including USDC, WETH, cbBTC, and AERO with their USD values, plus my total portfolio value and transaction activity level.”
Identifying smart contract vs EOA wallet
“Can you tell me if 0x9999888877776666555544443333222211110000 on Base is a regular wallet, a smart contract, or an EIP-7702 delegated account, and show me its Basename and recent activity?”
Technical details
Endpoint
GEThttps://agent-utils-x402.fishbowlinc.workers.dev/v1/base-wallet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-token portfolio snapshot of any Base address in a single call rather than making individual RPC calls per token. It is ideal when you need both on-chain metadata (account type, Basename, tx count) AND token balances in one response. Prefer over raw RPC calls when you need USD values pre-calculated, or when you need the curated list of 31 major Base tokens without manually specifying each contract address.
Side effects
- Invalid or malformed address format (must be 0x + 40 hex chars) returns validation error
- Address with no on-chain activity may return zero balances and minimal metadata
- RPC or node connectivity issues may cause temporary lookup failures
- Very new tokens not in the 31-token list will not appear in balances
- EIP-7702 delegation detection may lag if delegation is very recent
