The Lab
Collectibles Appraiser
Type a card or item name and this checks Scryfall (Magic), pokemontcg.io (Pokémon), YGOPRODeck (Yu-Gi-Oh!), and CardSight AI (sports cards, One Piece TCG) for a real match, showing whichever one actually has your item — never a fabricated "AI valuation" for a category none of these cover.
