Field notes
The owner can paste public addresses or sample active wallets, then fetch balances and inspect which values were clipped. The explanation says balance requests use a read-only proxy and that missing accounts count as zero. An analyst selects among count, sum, mean, and histogram queries; the page describes the budget as stopping further answers once spent.
