https://agent-data-tools.revmesh2074.workers.dev/zksync/allowanceOverview
ERC-20 token allowance on zkSync Era: how much a spender may move from an owner's wallet (allowance), raw and in token units, and whether the approval is unlimited. Use to check an approval before a swap or to audit risky open approvals; for the owner's balance use zksync_token_balance. Token is a ticker (USDC, USDT, WETH…) or a 0x contract; a missing contract is 404 and a non-ERC-20 422, both uncharged.
