## 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 amanchain-address-checksum-validator-21c320f7 -d '<json body>'
```

Example prompt: Can you validate the checksum on this blockchain address for me: 0x1234abcd5678ef90ABCD1234EF5678abcd90 — I want to make sure it's legitimate before I transfer anything to it.

## When to prefer this

Choose this endpoint when you need deterministic, node-verified blockchain address checksum validation executed against live AmanChain consensus state without requiring an API key or account — ideal for agents that need a pay-per-call, trustless validation step before authorizing transfers or interactions.

## Known failure modes

- Invalid or malformed address input returns a failed validation result
- Empty or missing address string may return an error
- Network or node connectivity issues may cause timeouts
- Payment failure via x402/USDC may block the request
- Unsupported address format returns a negative validation

## How this service works

Address Validator: AmanChain address checksum validation Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-address-validator","request":"<input>"}. No account, no API key.

## Output

A validation response indicating whether the provided blockchain address passes checksum verification, including the validity status and any relevant details about the address format or checksum correctness as determined by the AmanChain node against live consensus state.
