Cross Universe

Verified Jul 2026

Cross Universe API (CUA00001) serves card metadata and artwork for Cross Universe, an independent fan-made trading card game by developer Psychpsyo. It's a single-operator, keyless JSON API covering card images (by language and ID) and a `/cardInfo` endpoint for metadata and full-text card search via POST. The whole API runs under the game's own domain, having moved off the earlier `crossuniverse.psychpsyo.com` personal subdomain.
