How this service works
Look up a Base address: ETH balance, transaction count, contract or wallet, and ERC-20 balances (USDC by default, up to 5 tokens), read live from Base RPC. $0.003 USDC per call on Base.
Output
Returns the ETH balance (in wei and ether), total transaction count, wallet classification (EOA or contract), and balances for up to 5 specified ERC-20 tokens (defaulting to USDC) for the given Base address, read live from Base RPC at the time of call.
Example use cases
Verify DeFi user wallet activity
“Check the Base address 0xAbCd1234567890AbCd1234567890AbCd12345678 — I want to know how much ETH it has, how many transactions it's made, and whether it's a smart contract or a regular wallet.”
Confirm USDC payment received
“Has the payment landed yet? Look up Base wallet 0x1234567890abcdef1234567890abcdef12345678 and tell me its current USDC balance.”
Multi-token portfolio snapshot
“Give me a full snapshot of the Base wallet 0xDeAdBeEf1234567890DeAdBeEf1234567890DeAd — ETH balance plus balances for these ERC-20 tokens: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, 0x4200000000000000000000000000000000000006, and 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb.”
Technical details
Endpoint
POSThttps://api.avedaris.com/v1/paid/base-wallet-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, real-time on-chain data for a specific Base (L2) wallet address — especially when you need ETH balance, transaction count, contract/EOA classification, and ERC-20 token balances in a single call. Prefer this over Ethereum mainnet lookups when operating on Base, and over block explorer scraping when you need structured, agent-friendly JSON output with predictable schema.
Side effects
- Invalid address format (not 42-character 0x hex string) returns a validation error
- Invalid or non-Base ERC-20 contract address in the tokens array returns an error or zero balance
- RPC node unavailability causes a timeout or 503 error
- Address with no on-chain activity returns zero balances and zero transaction count (not an error)
- More than 5 token addresses in the tokens array is rejected
- Payment failure or insufficient USDC for the $0.003 fee causes a 402 error
