# Mint Intel: Ethereum Contract Introspection

> Mint Intel: Ethereum Contract Introspection is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-31).

Performs batched Ethereum contract analysis in one RPC call, classifying an address as EOA, delegated EOA, token, NFT, or plain contract, and extracting ERC-20/721/1155 metadata, proxy info, and bytecode details.

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-ethereum-contract-introspection-42d816ea
```

Example prompt: Can you inspect the Ethereum contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and tell me what type it is — ERC-20 token, NFT, proxy, or plain contract — along with its name, symbol, decimals, and who owns it?

## When to prefer this

Choose this endpoint when you need comprehensive contract classification and metadata in a single call rather than issuing multiple eth_call or eth_getCode RPC requests yourself. It is particularly valuable for agents that need to quickly determine whether an Ethereum address is a user wallet, a token, an NFT collection, or a proxy contract, and want ERC-20/721/1155 metadata and ownership info all in one response. Prefer it over raw RPC calls or block explorers when building automated pipelines that process many unknown addresses.

## Known failure modes

- Invalid or malformed 0x address returns a 400 error
- Address not found or zero-balance EOA with no code returns kind: EOA with empty bytecode fields
- Network congestion or RPC node unavailability may cause timeouts
- Contract that does not implement standard interfaces returns empty metadata fields
- ERC-20 metadata calls to non-standard tokens may return null fields if the contract omits name/symbol/decimals

## How this service works

Best-effort Ethereum contract introspection in one batched RPC call - bytecode presence and size, ERC-20 metadata (name, symbol, decimals, totalSupply), ERC-721 / ERC-1155 / ERC-165 detection, Ownable owner() and proxy implementation; classifies EOA, EIP-7702 delegated EOA, token, NFT or plain contract.

## Output

Returns a JSON object containing the address, its kind classification (EOA, EIP-7702 delegated EOA, ERC-20 token, ERC-721 NFT, ERC-1155, or plain contract), bytecode presence and size, keccak hash of the bytecode, supported ERC standards array, ERC-20 metadata fields (name, symbol, decimals, totalSupply) if applicable, the Ownable owner() address if present, and proxy implementation address if a proxy pattern is detected.
