How this service works
EVM Contract Introspection (ethereum). Ethereum contract introspection: contract vs wallet (incl. EIP-7702 delegation), bytecode size, proxy detection (EIP-1967 implementation/admin/beacon and legacy OpenZeppelin slots) and ERC-20 name, symbol, decimals and total supply.
Output
Returns on-chain introspection data for the specified Ethereum contract address, including the contract ABI (function signatures, events, inputs/outputs), bytecode, and available deployment or metadata fields sourced directly from the Ethereum blockchain.
Example use cases
Audit a DeFi protocol contract
“I need to inspect the Ethereum smart contract at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D — can you pull its on-chain data, ABI, and contract metadata so I can review what functions it exposes?”
Verify a token contract before investing
“Before I put money into this token, can you look up the Ethereum contract at 0xdAC17F958D2ee523a2206206994597C13D831ec7 and show me its on-chain introspection data so I can confirm it's a legit ERC-20?”
Reverse-engineer an unknown contract
“I found this Ethereum contract address 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 in a transaction and have no idea what it does — can you fetch its contract data from the chain so I can understand its interface?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/ethereum/contract/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically inspect a deployed Ethereum smart contract's interface and on-chain data without manually querying Etherscan or running your own node. It is well-suited for agents that need to understand a contract's ABI before interacting with it, verify contract legitimacy, or extract deployment metadata as part of a DeFi analysis or security audit workflow.
Side effects
- Address is an EOA (externally owned account), not a contract — returns empty or error
- Invalid Ethereum address format — returns 400 or validation error
- Contract not verified or bytecode not available on-chain — partial data returned
- Network connectivity issues to Ethereum node — timeout or 503
- Address is a self-destructed contract — may return empty bytecode
