Try the Alt auctions API

Searches Alt's own currently live auctions -- the same pool shown on alt.xyz/browse's "Auctions" tab filtered to the Alt source. Unlike alt-search, this never returns another source auction house's listings or Alt's own fixed-price items. See alt-categories for the accepted category/grading_company/sort values.
