How this service works
Kostenlose Guides, Solo-Playbooks und Artikel zu KI, Automation und Side Hustles — für Menschen, die mit echten Systemen online Einkommen aufbauen wollen. Transparent finanziert über faire Affiliate-Links.
Output
Returns a JSON object with a 'result' field containing the checksummed Ethereum address in EIP-55 mixed-case format, and a 'status' field indicating success or failure of the operation.
Example use cases
Normalize wallet address before transfer
“Before I send funds, can you apply the EIP-55 checksum to this Ethereum address so I know I have the correct casing: 0xab5801a7d398351b8be11c439e05c5b3259aec9b”
Validate DeFi contract address format
“I have this smart contract address and need to make sure it's properly checksummed before I integrate it into my dApp — can you run it through the EIP-55 checksum formatter: 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae”
Sanitize addresses in bulk data pipeline
“I'm cleaning a dataset of Ethereum addresses and need to normalize this one to its checksummed form: 0x71c7656ec7ab88b098defb751b7401b5f6d8976f”
Technical details
Endpoint
POSThttps://kihustle.tech/api/v1/ethereum-address-checksumWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call API to convert or normalize Ethereum addresses to EIP-55 checksum format without setting up a local Web3 library. Ideal for agents processing individual addresses on-demand in blockchain workflows where installing ethers.js or web3.py is impractical.
Side effects
- Invalid Ethereum address format — returns error if the input is not a valid hex address
- Address too short or too long — standard Ethereum addresses must be 42 characters including '0x' prefix
- Missing 'address' field in request body — results in a bad request error
- Non-hex characters in address string — will fail checksum computation
