How this service works
EIP-55 mixed-case checksum for a 20-byte EVM (Ethereum/Base) hex address, via Keccak-256. Normalize and verify addresses before a transfer.
Output
Returns the EIP-55 mixed-case checksummed representation of the provided Ethereum address, where uppercase and lowercase hex letters encode a checksum that allows detection of address typos.
Example use cases
Normalize wallet address before on-chain transfer
“Before I send funds, can you convert 0xd8da6bf26964af9d7eed9e03e53415d37aa96045 to its proper EIP-55 checksummed address so the receiving system accepts it?”
Verify smart contract address checksum
“I need the EIP-55 checksummed version of this smart contract address 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae — can you convert it for me?”
Standardize addresses in a DeFi integration
“Our DeFi app requires EIP-55 format — can you convert 0x5aaeb6053f3e94c9b9a09f33669435e7ef1beaed to the mixed-case checksummed form?”
Technical details
Endpoint
POSThttps://agentbit.app/v1/address/eip55?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to convert or normalize an Ethereum-compatible address to EIP-55 mixed-case checksum format without requiring a full Ethereum node or library. Ideal for lightweight agents that need address standardization as a pay-per-call primitive with no API key setup.
Side effects
- Invalid address format: input is not a valid 40-character hex string (with or without 0x prefix)
- Malformed input: missing or empty address field returns an error
- Non-Ethereum address formats (e.g. Bitcoin, Solana) are not supported
