How this service works
One-call Base wallet profile: ETH and major token holdings (USDC, WETH, USDT, DAI, cbBTC, cbETH, AERO, EURC) with USD values, total USD, nonce (lifetime sent tx count), EOA vs contract (incl. EIP-7702 smart account), recent ERC20 transfers in/out over ~5,000 blocks (~3h) with net flow, top counterparties labeled where known (Uniswap, Aerodrome, 1inch, 0x, Aave, Seaport, bridges), and a simple wallet type. Free public data, deterministic, no LLM.
Output
A JSON object containing the wallet address, ETH balance, total USD value across all holdings, an array of token holdings (symbol, amount, USD value), recent activity stats (transfer counts in/out over recent blocks), nonce, wallet type classification (e.g. 'active'), whether the address is a contract, and an array of top counterparties with labels and interaction counts.
Example use cases
Due diligence on a new counterparty
“Before we send funds to 0xAbc123...def456, can you check their Base wallet profile — I want to know if it's a contract or a regular wallet, how active it's been recently, and what tokens they hold?”
Portfolio snapshot for a DeFi user
“Give me a full breakdown of wallet 0x1234abcd...5678 on Base — total USD value, token holdings, ETH balance, and the top protocols they've interacted with.”
Flagging suspicious wallet activity
“Can you look up the Base wallet profile for 0xDead...Beef and tell me how many transfers they've made recently and which addresses they interact with most — I'm trying to figure out if this address looks legitimate.”

Endpoint
GEThttps://138-197-15-135.sslip.io/v1/base/wallet-profile?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a rich, aggregated onchain profile of a Base/EVM wallet in a single call — covering balances, holdings, activity, and counterparties — rather than making multiple separate RPC calls. It is particularly useful for AI agents that need to quickly assess wallet health, portfolio value, or transaction history without building custom blockchain data pipelines. Pay-per-call via x402 makes it suitable for ad-hoc or low-volume lookups without subscription overhead.
Side effects
- Invalid or malformed EVM address returns an error
- Address not found on Base returns nulls for most fields
- Payment failure (x402) if USDC payment of $0.012 is not included
- Rate limiting or server errors if the underlying RPC is congested
- Newly created wallets may return empty holdings and zero activity
