## 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-eip-55-checksum-converter-d325e5b5 -d '<json body>'
```

Example prompt: Can you convert this Ethereum address to its EIP-55 checksum format: 0xd3cda913deb6f279967d360587e7a4a3d3ed0b32?

## When to prefer this

Use this endpoint when you need to programmatically apply EIP-55 checksumming to Ethereum addresses — especially in pipelines that ingest raw or lowercase addresses that need to be normalized before display, storage, or transfer. Prefer this over manual checksumming logic when building automated workflows or agents that handle wallet addresses.

## Known failure modes

- Invalid Ethereum address format (not a 40-hex-character string) returns an error
- Missing 'address' field in request body causes validation failure
- Address with non-hex characters causes processing error
- Network timeout or service unavailability returns a non-200 response
