Endpoint Playground
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 does not expose one; see alt-sold-listings for per-grade sold prices on specific listings.
14 Oct 2026: 1,183 recent_sales; 0 fields had a value in every checked item and 2 varied between items.
Sample value profiles: date: 2026-07-07 to 2026-10-12; price: 2,760 to 516,000, median 9,200.
