BNS Bulk Reverse Lookup

Resolve many Stacks addresses to their primary .btc / BNS name in a single call (up to 25, resolved in parallel). Returns an { address: name|null } map — built for labelling leaderboards, token holder lists, member rosters, whale lists, and airdrop lists all at once. For a deep single-address identity profile (all names, namespaces, renewal, zonefile) use the BNS Resolver tool instead.
