## 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 delx-commerce-address-normalize-540134c5 -d '<json body>'
```

Example prompt: Can you normalize this Ethereum address to its proper checksummed format: 0xabcdef0000000000000000000000000000000001?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call, no-signup solution to normalize or checksum blockchain addresses — especially within agent workflows where reliability and verifiable delivery matter. Prefer this over rolling your own checksum logic when operating on Base or Solana ecosystems.

## Known failure modes

- Invalid address string returns error response with ok: false
- Malformed hex input may fail validation
- Non-Ethereum address formats may not be supported

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with ok: true, the schema identifier 'delx/util-address-normalize/v1', and the normalized canonical (EIP-55 checksummed) address string.
