GET /alt/auctions

Search Alt's own live 24/7 auctions

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: it always uses a search key scoped server-side to Alt's own live auction pool. Credential-free public data from Alt's own search backend. See alt-categories for the accepted category/grading_company/sort values.

API key required. Paste a full key or rotate one from the API Keys page.
