# Mint Intel: Base Chain Contract Code Inspector

> Mint Intel: Base Chain Contract Code Inspector is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-31).

Inspects the bytecode of any Base address to determine if it's a contract or EOA, its code size, keccak hash, proxy type, and optionally its full deployed bytecode.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 mint-intel-base-chain-contract-code-inspector-36cee8ff
```

Example prompt: Can you check if the Base address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 is a smart contract or a regular wallet, and if it's a contract, what kind — is it a proxy or delegated EOA?

## When to prefer this

Use this endpoint when you need to classify a Base chain address as EOA or contract, detect proxy patterns (EIP-1167, EIP-7702), retrieve bytecode metadata, or fetch full deployed bytecode for auditing — specifically on the Base L2 network. Prefer this over Ethereum equivalents when the address is on Base.

## Known failure modes

- Invalid or malformed address format returns an error
- Address not found on Base returns codeSizeBytes of 0 and isContract false (valid EOA)
- Network or RPC timeout may return a 5xx error
- Requesting full=1 on a very large contract may be slow or hit size limits

## How this service works

Is a Base address a contract? eth_getCode: code size, keccak code hash, EOA vs contract, EIP-7702 delegated EOA (and its delegate), EIP-1167 minimal-proxy target, bytecode prefix; ?full=1 returns the whole deployed bytecode.

## Output

Returns a JSON object containing the address, a boolean isContract flag, code size in bytes, keccak hash of the bytecode, a bytecode prefix, EOA vs contract classification, EIP-7702 delegation info (delegate address if applicable), EIP-1167 minimal proxy target address if applicable, and optionally the full deployed bytecode when full=1 is passed.
