Mint Intel: Base Chain Contract Introspection
x402
Mint Intel: Base Chain 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 on-chain introspection of any Base chain address, classifying it as EOA, EIP-7702 delegated EOA, ERC-20 token, NFT, or plain contract, with metadata extraction in a single RPC call.

How this service works
Best-effort Base 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 with the address, a kind classification (EOA, EIP-7702 delegated EOA, ERC-20 token, NFT ERC-721, NFT ERC-1155, or plain contract), bytecode presence and size, detected ERC standards array, ERC-20 metadata (name, symbol, decimals, totalSupply) if applicable, Ownable owner() address if applicable, and proxy implementation address if applicable — all gathered in a single batched RPC call.
Example use cases
Verify token contract before DeFi interaction
“Before I swap on Base, can you check 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and confirm it's a legitimate ERC-20 token — get me its name, symbol, decimals, total supply, and whether it's a proxy contract?”
NFT contract classification for collector
“I just found this Base contract at 0x7c6b91D9Be155A6Db01f749217d76fF02A7227F2 — can you tell me if it's an ERC-721 or ERC-1155 NFT contract and who the owner is?”
Smart contract security pre-audit check
“Can you do a quick introspection on Base contract 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — I need to know its bytecode size, whether it's a proxy with an implementation address, and who the Ownable owner is?”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/base/contract/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, single-call snapshot of any Base chain address — especially when you want contract classification plus token metadata plus proxy and ownership data without making multiple separate RPC calls. Prefer this over raw eth_getCode when you need interpreted results and token standard detection. Choose this over Ethereum equivalents specifically for Base (L2) addresses.
Side effects
- Invalid or malformed address format (non-0x-prefixed or wrong length) returns 400 error
- Address not found or network error returns 5xx error
- Contract may be partially compliant with a standard, causing incomplete metadata fields
- ERC-20 metadata calls may fail silently on non-standard tokens, returning nulls
- Proxy detection limited to EIP-1967 and common patterns; exotic proxies may not be detected
- Payment failure (x402) returns 402 if USDC payment is not correctly submitted
