Server tool list (3)

Raw names from tools/list. Only developers need these.

price_deckPrices a pasted decklist (any TCG: Magic, Pokemon, Yu-Gi-Oh, One Piece, Lorcana, and 18+ more) and returns a ready-to-buy TCGplayer cart link. Paste the raw decklist text — one card per line, quantity + name, e.g. '4x Lightning Bolt' or '2 Counterspell (7ED)'. Returns a priced table (qty, name, set, unit price, line total), a grand total, any lines that couldn't be resolved with did-you-mean suggestions, and one affiliate-wrapped buy link.
price_cardLooks up the current market price of a single TCG card (any of 22+ games: Magic, Pokemon, Yu-Gi-Oh, One Piece, Lorcana, and more). Returns the best match's price and an affiliate-wrapped TCGplayer product link, plus alternates when the name is ambiguous.
list_printingsLists every known printing of a TCG card (any of 22+ games) — every set it was printed in, with per-finish (nonfoil/foil) prices and treatment tags (border, frame, promo, full art). Use this instead of price_card when the buyer wants to compare printings, find the cheapest version, or find a specific treatment (e.g. borderless, showcase). Returns a `grouping` field: "oracle_id" means the printings are confirmed the exact same card; "normalized_name" is a best-effort name match that can occasionally over- or under-group.
