## 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 evm-contract-creator-lookup-b4c7556c -d '<json body>'
```

Example prompt: Who deployed the contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — I want the creator address, when it was deployed, whether it's verified, and if it's a proxy contract.

## When to prefer this

Choose this endpoint when you need comprehensive contract provenance data — deployer identity, deployment timestamp, proxy architecture, and scam signals — in a single call across multiple EVM chains. Prefer it over block explorer scraping when you need structured JSON output with named creator labels, ENS resolution, and scam flags combined. It covers Ethereum, Base, Arbitrum, Optimism, Polygon, and zkSync in one unified API.

## Known failure modes

- Contract address not found on the specified network — returns null fields
- Unsupported network specified — returns validation error
- Malformed contract address — request rejected
- Network congestion causing slow data retrieval — timeout
- Contract too new for indexing — incomplete or missing creation data
- Creator address not labeled or named — name and ENS fields return null

## 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 creator's wallet address (with ENS name and known label if available), a scam flag for the creator, the creation transaction hash and date, the contract name, verification status, proxy type, a list of implementation addresses, a scam flag for the contract itself, and the data source used.
