https://agent-data-tools.revmesh2074.workers.dev/zksync/is-contractOverview
Check whether a 0x address on zkSync Era is a smart contract or a plain wallet: bytecode size, and whether it is an EIP-1167 minimal proxy and which implementation it points to. Use before sending funds or approving a spender; for a fuller risk verdict use check_counterparty. A malformed address is rejected with 400, uncharged.
