Returns one card design's identity, full population report (across every grading company and grade Alt tracks), and a recent raw sales feed -- the "is this card actually rare, and what does it sell for" data for a specific card design, independent of any single listing. asset_id comes from a prior alt-search/alt-sold-listings/alt-card-search result's asset_id field. recent_sales has no per-transaction grade breakdown -- Alt's own API does not expose one; see alt-sold-listings for per-grade sold prices on specific listings. Credential-free public data from Alt's own GraphQL API.
