## 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 vextorium-evm-contract-creator-lookup-512af856 -d '<json body>'
```

Example prompt: Who deployed the contract 0x532f27101965dd16442E59d40670FaF5eBB142E4 on Base — can you get me the creator address, deployment date, creation transaction, and whether it's verified or flagged as a scam?

## When to prefer this

Use this endpoint when you need to identify the original deployer of an EVM smart contract, verify its deployment history, or flag potential scams across Ethereum, Base, Arbitrum, Optimism, Polygon, or zkSync. Prefer it over block explorer UIs when you need machine-readable deployment metadata in a single API call. It is especially valuable when auditing unknown contracts, researching DeFi protocols, or building security tooling that needs creator provenance and proxy detection in one response.

## Known failure modes

- Contract address not found on the specified network — returns null fields
- Invalid contract address format — returns validation error
- Network not supported — enum validation error if network is outside the allowed list
- Contract is unverified — verified field returns false, name may be null
- Proxy implementation not resolvable — implementations array may be empty
- External data source (Blockscout etc.) temporarily unavailable — may return partial or null data

## How this service works

Who deployed an EVM contract and when: creator address (named when known), creation transaction and date, contract name, verification, proxy type and implementation, and scam flag.

## Output

A JSON object containing: the contract address and network, the deployer's address (with ENS name and named label if known), the creation transaction hash, the ISO 8601 creation date, the contract name, a verified boolean, proxy type (null if not a proxy), an array of implementation addresses (for proxies), a scam flag, and the data source (e.g. Blockscout).
