KeyForge Card Price API

KeyForge, designed by Richard Garfield (creator of Magic: The Gathering) and published initially by Fantasy Flight Games, pioneered a unique model in the TCG space: every deck is algorithmically generated, unique, and unchangeable. No deckbuilding, no boosters, no trading individual cards — you buy a pre-shuffled deck, and that exact deck is yours to play. The game has cycled through publishers (now managed by Ghost Galaxy) and released multiple sets including Call of the Archons, Age of Ascension, Worlds Collide, and Mass Mutation. The unusual format created an unusual secondary market, where specific "godly" decks — algorithmically fortunate combinations of cards — trade for significantly more than their retail box price.

Pricing data in KeyForge is unusual because the traditional "individual card price" model does not apply — decks are the tradeable unit. However, sealed product (archon decks, sealed display boxes, booster decks from deluxe releases) does follow standard TCG pricing patterns, with out-of-print sets appreciating as supply tightens. Specific iconic cards that appear in some decks also have meaningful cross-deck significance, and TCGPlayer lists these as individual singles for players wanting a reference view.

TCG API covers KeyForge products to the extent TCGPlayer lists them — sealed product, reprint archon decks, and the individual-card references that exist. For a game that defies normal TCG pricing conventions, our data gives you a reliable read on the aftermarket for sealed KeyForge product.
