CardYield is a participant in the eBay Partner Network (EPN). Many of the outbound links in this app — including the “search on eBay” icons on each checklist card, the eBay search buttons in your collection, and the eBay lookups on the wax and public share pages — are affiliate links.
If you click one of these links and make a qualifying purchase on eBay, CardYield may earn a commission at no additional cost to you. Our earnings help keep the app running and let us keep building features for collectors, breakers, and small dealers.
Our participation in the eBay Partner Network does not influence the listings we surface. We do not receive editorial input from eBay, and we do not weight results in favor of any particular seller.
Live prices shown in CardYield are aggregated from public APIs including eBay Browse (active listings), the Scryfall API (Magic: The Gathering), the Pokemon TCG API (Pokemon), and where available, SoldComps for sold eBay comparables. We do not warrant accuracy — these figures are best-effort snapshots, not appraisals.
Card, subset, variation, and parallel data are sourced from manufacturer checklists (Topps sell sheets and product PDFs) and cross-referenced with hobby publications like Checklist Insider. CardYield uses this data for personal collection reference within the app; we do not republish or resell it.
