Proxy / Upgrade Detector
x402
Proxy / Upgrade Detector is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).
Reads EIP-1967 proxy storage slots on a contract to detect upgradeability, current implementation address, and admin/upgrader identity — flagging dangerous EOA-controlled upgrades with no timelock or multisig.

How this service works
Reads the EIP-1967 proxy slots live: is the contract upgradeable, what's the current implementation, and WHO can upgrade it. Flags the dangerous case — an EOA admin that can swap the logic at any block with no timelock/multisig. Upgradeability is a rug vector static scans miss.
Output
Returns whether the contract is an upgradeable proxy (EIP-1967 compliant), the current implementation contract address, the admin/upgrader address, the type of upgrade authority (EOA vs multisig vs timelock), and risk flags indicating whether the setup represents a dangerous single-point-of-control rug vector.
Example use cases
DeFi rug risk pre-investment check
“Before I ape into this new yield farm, can you check if the contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 is an upgradeable proxy and whether the upgrade admin is just a plain wallet with no timelock?”
Token contract security audit
“I'm about to list this token on our platform — audit the contract 0xdAC17F958D2ee523a2206206994597C13D831ec7 for proxy upgradeability and tell me if a single EOA controls the implementation with no multisig protection.”
Protocol due diligence for DAO proposal
“Our DAO is considering integrating with this lending protocol at 0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE6 — can you read its EIP-1967 proxy slots and tell us who can upgrade it and whether there's any timelock or multisig in place?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/proxy-checkWhen to prefer
Use this endpoint when you need to assess smart contract upgradeability risk, specifically the EIP-1967 proxy pattern, and want to know whether an EOA (single wallet) controls upgrades without a timelock or multisig. Prefer this over static analysis tools when you need live on-chain slot reads rather than bytecode inspection, since static scans miss runtime proxy configurations. Ideal as a pre-investment or pre-integration security check for DeFi protocols and token contracts.
Side effects
- Invalid or non-existent contract address returns an error or empty proxy data
- Contract is not a proxy — returns non-upgradeable result with no implementation/admin slots
- RPC timeout or chain data unavailability causes failed fetch
- Malformed address string returns a validation error
- Non-EIP-1967 proxy patterns may not be fully detected
