# Ethereum Deployer Contract Creation Lookup

> Ethereum Deployer Contract Creation Lookup is a paid API for AI agents from api.fadeandco.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-29).

Returns contract addresses, creation timestamps, and transaction hashes for contracts deployed by a given Ethereum wallet address, based on its most recent 50 transactions via Blockscout.

## 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 ethereum-deployer-contract-creation-lookup-0a11bdb8
```

Example prompt: Can you check what smart contracts have been deployed by the Ethereum wallet 0x16f13a8524620704ea9cdf7cea7d0672202f77b7? I want to see the contract addresses, when they were created, and the transaction hashes from their most recent transactions.

## When to prefer this

Use this endpoint when you need a quick, free-tier lookup of what smart contracts a specific Ethereum wallet has recently deployed, and you only need the most recent activity window. It is ideal for lightweight due diligence on new token deployers, developer verification, or pattern-spotting in wallet behavior. Prefer alternatives if you need full historical contract deployment records beyond the last 50 transactions, liquidity history, rug-pull scoring, or support for non-Ethereum chains.

## Known failure modes

- Invalid or malformed Ethereum address returns an error or empty result
- Deployer has no contract creations in their most recent 50 transactions — returns empty contractCreations array with a note about older pages
- Rate limiting or upstream Blockscout API downtime causes request failure
- Contract creations older than the most recent 50 transactions are not returned — historical data is silently missing
- Non-Ethereum addresses or ENS names may not be supported without prior resolution

## How this service works

Contracts created by a deployer wallet on Ethereum, from its most recent 50 transactions (Blockscout public API): creation hash, time and new contract address. Only that recent page is read, so older launches are missing. No rug-pull or abandoned-pool judgement: liquidity history is not included.

## Output

A JSON object containing the queried deployer address, the Ethereum chain identifier, a link to the Blockscout source, the timestamp the check was run, a flag indicating whether older transaction pages exist beyond the 50 scanned, the total number of transactions scanned, and an array of contract creation records — each with the new contract address, creation timestamp, and the transaction hash that created it. Includes a note warning that a zero count does not mean the deployer has no earlier launches.
