DeckBrew is a website for building Magic: The Gathering (MTG) decks. Although the website is still under development, it already has a functional API for retrieving information on MTG cards. This information includes a listing of all MTG cards; listings of cards from a given multiverse, set, or color; details on a single card, etc. All textual information presented through the API belongs to Wizards of the Coast. The DeckBrew API is still in beta, and changes may be made at any time.
