Mint Intel: Base Chain Contract Code Inspector
x402
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.

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.
Example use cases
Verify NFT contract authenticity
“Before I interact with this Base address 0xAbCd1234abcd1234abcd1234abcd1234abcd1234 — can you tell me if it's actually a deployed contract, what its bytecode hash is, and whether it's a minimal proxy pointing somewhere else?”
Detect smart account delegation
“I think this Base address 0x1111111111111111111111111111111111111111 might be an EIP-7702 delegated EOA — can you check what contract it delegates to?”
Audit deployed contract bytecode
“Can you pull the full deployed bytecode for the Base contract at 0xBA12222222228d8Ba445958a75a0704d566BF2C8 so I can verify it matches what was audited?”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/base/code/:address?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
