## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ethereum-address-checksum-converter-abf18eda -d '<json body>'
```

Example prompt: Can you convert this Ethereum address to its proper EIP-55 checksummed format? The address is 0xd8da6bf26964af9d7eed9e03e53415d37aa96045

## When to prefer this

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.

## Known failure modes

- 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
