Ethereum Address Inspector
x402
Ethereum Address Inspector is a paid API for AI agents from automaton-tx-explainer.vercel.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-16).
Inspect any Ethereum address to determine its type (EOA, contract, or EIP-7702 delegated), ETH balance, nonce, proxy implementation details, and ERC-20 token metadata.

How this service works
Inspect any Ethereum address: EOA vs contract vs EIP-7702 delegated, ETH balance, nonce, proxy implementation (EIP-1967/1167/zos), and ERC-20 name/symbol/decimals/supply.
Output
Returns a structured object describing the address type (EOA, contract, or EIP-7702 delegated account), current ETH balance, nonce, proxy implementation address if applicable (detected via EIP-1967, EIP-1167 minimal proxy, or ZOS patterns), and if the address is an ERC-20 token contract: its name, symbol, decimals, and total supply.
Example use cases
Identify unknown Ethereum address type
“I found this Ethereum address 0xdAC17F958D2ee523a2206206994597C13D831ec7 in a transaction — can you tell me if it's a regular wallet or a smart contract, and if it's a token contract, what token is it?”
Verify proxy contract implementation
“Check whether the contract at 0x1F98431c8aD98523631AE4a59f267346ea31F984 is a proxy and if so, tell me what implementation address it's pointing to.”
Check wallet nonce and balance before sending
“Before I send a transaction, can you look up the ETH balance and current nonce for my Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045?”
Technical details
Endpoint
GEThttps://automaton-tx-explainer.vercel.app/v1/ethereum/address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive single-call overview of any Ethereum address — combining type classification, balance, nonce, proxy detection, and ERC-20 metadata in one shot. Prefer it over block explorer manual lookups or multi-call RPC sequences when building agents that need to reason about unknown addresses on Ethereum mainnet specifically (not Base or BNB Smart Chain, which have sibling endpoints).
Side effects
- Invalid address format (not matching 0x + 40 hex chars) returns a validation error
- Address not found or RPC node unavailable returns a connectivity/timeout error
- Non-ERC-20 contract at address returns empty token metadata fields
- Rate limiting or payment failure (x402) blocks the request
