GET /alt/sold-listings

Search Alt's completed sales archive

Searches Alt's global archive of completed card sales, aggregated across every source auction house its search carries -- the "market data" side of Alt's card-investment-marketplace positioning. This is a separate index from alt-search/alt-auctions, scoped to a rolling recent time window, not a filtered view of live listings. Pass auction_house=Alt to see only Alt's own completed auctions. Credential-free public data from Alt's own search backend. See alt-categories for the accepted category/auction_house/grading_company values.
