attic_get_changes ~234 tokens
Ledger of roster and gathering moves since the prior weekly cut. Use this for 'what changed', rank moves, names that entered or left a top 5. Optional since (YYYY-MM-DD), market, and layer. layer=beyond is Attic Beyond. An empty list means the rosters did not move.

attic_list_markets ~108 tokens
List the four Attic collector markets (rare coins, sports cards, collector cars, fine art) with Headlines, Beyond, and Creators page URLs on atticcapital.com. Use this when you need the canonical page to link, not a top-5 roster.
