Paper Collage API

One endpoint serves every workflow — this page documents motion_paper_collage-v1, the current version. Credits are debited at submission (1 cr/s standard, 1 cr/s pro); a failed generation is refunded automatically. Earlier versions of this endpoint, if any, keep being served under their own names.
