## How to call it through Zero

```sh
zero fetch --capability chainray-contract-verify-91bbcc16
```

Example prompt: Can you check if the smart contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 is verified on Ethereum and show me its verification details?

## When to prefer this

Use this endpoint when you need to programmatically check whether a smart contract has verified source code on a given blockchain, retrieve its ABI, or validate contract transparency before interacting with it. Prefer this over block explorer manual lookups when automating due diligence, auditing token contracts, or building agent workflows that require knowing if a contract is open and auditable.

## Known failure modes

- Invalid or malformed contract address returns an error or empty result
- Contract not deployed at the given address returns unverified/not found
- Unsupported chain identifier returns an error
- Address is a wallet, not a contract — may return unverified or error
- Network timeout or upstream RPC failure returns 5xx error
- Missing required 'address' query parameter returns 400-level error
