Summary
Batch-checks wallet addresses against Nansen's database to identify which ones are tagged as "smart money" or institutional funds. You pass in a comma-separated list of addresses and get back labels, categories, and optionally balance data for each. The main use case is filtering large address lists to find the wallets worth paying attention to, like proven traders or fund wallets that historically make good moves. It handles invalid addresses gracefully with per-result error messages instead of crashing. If you're doing on-chain research or trying to figure out who the sophisticated players are in a transaction graph, this beats manually looking up addresses one by one.
