Is this contract an upgradeable proxy, and where does its current code live? Returns the proxy standard, implementation, admin and beacon addresses, whether the implementation has code, and the storage slots and block read. Base, Ethereum and major L2s; optional raw storage slots decoded. $0.003/call via x402 (Base or Solana) or MPP. Also GET with query parameters. Free worked example: GET /api/v1/proxy-implementation/example.
