How this service works
Look up an EVM address or ENS name on Ethereum + Base: ENS forward/reverse + text records, EOA vs contract (EIP-7702 delegation flag), native balance, tx count, USDC/USDT balances, and ERC-20 name/sy…
Output
Returns a JSON object with: resolved address, ENS name, timestamp, data source, and per-chain data for Ethereum and Base including native ETH balance, USDC/USDT stablecoin balances, transaction count, code size, contract flag, EIP-7702 delegation flag, and ENS text records (avatar, URL, Twitter, GitHub, description).
Example use cases
Wallet due diligence before sending funds
“Before I send money to 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045, can you check its ENS name, ETH balance, stablecoin holdings, and whether it's a smart contract or a regular wallet on Ethereum?”
ENS profile enrichment for a dapp
“I have the ENS name rainbow.eth — can you fetch its resolved address, avatar, Twitter handle, website URL, and any other text records it has set?”
Cross-chain balance check on Base
“What's the USDC balance and transaction count for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base, and is it an EIP-7702 delegated account?”
Technical details
Endpoint
POSThttps://lumenworks-x402-decoder.onrender.com/v1/evm/address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-chain snapshot of any EVM address or ENS name in a single call — combining identity (ENS resolution + text records), asset balances (ETH + USDC/USDT), and account type classification (EOA vs contract, EIP-7702) across both Ethereum mainnet and Base. Prefer it over block explorer APIs when you need structured JSON output ready for agent consumption without manual scraping.
Side effects
- Invalid or non-existent ENS name returns null for ENS fields
- Address with no on-chain activity returns zero balances and tx count
- RPC node unavailability may cause timeout or 503 error
- Malformed address input returns a 400 validation error
- ENS name not registered returns no resolution
