How this service works
Takes an address (0x + 40 hex) and returns the contract bytecode on Ethereum mainnet via eth_getCode. Base RPC read of an address, block or transaction.
Output
Returns the raw hex-encoded bytecode (EVM code) stored at the given Ethereum address on mainnet. If the address is an externally owned account (EOA) with no contract, it returns '0x'. If a contract is deployed there, it returns the full bytecode string.
Example use cases
Check if address is a contract
“Is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 a smart contract or a regular wallet on Ethereum mainnet? Fetch its bytecode to check.”
Verify contract deployment
“I just deployed a contract to 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum mainnet — can you confirm there's actual bytecode there to make sure it deployed successfully?”
Audit contract code presence
“Pull the raw bytecode for the Ethereum address 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D so I can check whether there's a contract running there.”

Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/x402_eth_reads_v1/eth_mainnet_eth_getcode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify whether a contract is deployed at a specific Ethereum mainnet address, retrieve raw EVM bytecode for analysis or auditing, or distinguish between EOAs and smart contracts programmatically. Prefer this over general-purpose Ethereum RPC gateways when you want a pay-per-call, agent-friendly interface with no API key setup.
Side effects
- Invalid address format (not matching 0x + 40 hex pattern) returns a validation error
- Address with no deployed contract returns '0x' (empty bytecode, not an error)
- Network or RPC node unavailability causes timeout or 5xx error
- Rate limiting or quota exhaustion may result in 429 or payment-related errors
- Self-destructed contracts may return '0x' even if previously deployed
