Cross Universe

About Cross Universe

Cross Universe API (CUA00001) provides programmatic access to card images and metadata for the Cross Universe trading card game, covering both English and Japanese versions. Card images are served via a URL path specifying language and card ID, while a /cardInfo endpoint returns detailed JSON metadata for a given card, including name, level, card type, base types, effect text (both as plain text and as structured effect objects), deck limit, release date, illustrator, and idea credit where available.

The metadata also includes relational data between cards, such as which cards are mentioned in a card's text, which cards appear visually in its illustration, and cross-references like mentionedOn and visibleOn. Additional fields cover counter and type mentions within card text, character appearances in illustrations, links to the card's page on crossuniverse.jp, web-sourced lore and effect descriptions, and variant/legacy ID information for cards that exist in multiple versions.

This API is intended for developers building tools, card databases, or applications related to the Cross Universe card game who need structured access to card images and detailed card data.
