Snap Freeze API

The trending stop-and-snap reel: a raised palm stops your model, the camera explores the first piece, a finger snap switches it to the second, and they walk on. From a photo of your model and two of your pieces.

POST/v1/generateworkflow: snap_freeze-v1

One endpoint serves every workflow — this page documents snap_freeze-v1, the current version. Credits are debited at submission (2.2 cr/s standard, 4.4 cr/s pro, 23 cr/s ultra); a failed generation is refunded automatically. Earlier versions of this endpoint, if any, keep being served under their own names.
