## 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 getcontractcreation-1fc2a7e1 -d '<json body>'
```

Example prompt: Who deployed the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum mainnet (chain ID 1)? I need the creator's wallet address and the deployment transaction hash.

## When to prefer this

Use this endpoint when you need to identify who originally deployed a smart contract and when, specifically needing the creator wallet address and deployment transaction hash on any EVM-compatible chain supported by Etherscan. Prefer this over general blockchain RPC calls when you want a clean, structured response without parsing raw transaction receipts.

## Known failure modes

- Invalid or non-existent contract address returns empty or error result
- Chain ID not supported by Etherscan returns an error
- More than 5 contract addresses submitted exceeds the limit
- Contract address is an EOA (externally owned account), not a contract
- Network timeout or Etherscan API rate limit causes failure
- Malformed comma-separated address list causes parse error

## How this service works

Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.

## Output

Returns the deployer/creator wallet address and the transaction hash of the contract creation transaction for each queried contract address, sourced via Etherscan on the specified EVM chain.
