Generation Tools

Pose Variation

Re-pose the person in an existing photo while guaranteeing every garment, accessory and held or worn item stays exactly as photographed — same person, same outfit, new body posture.

Pose Variation result — same person and outfit in a new pose

What it does

Give this tool an existing on-model photo and a target pose, and it re-poses the person while locking everything else in place — the garment, any accessories, and anything they're holding or wearing stays identical to the source photo. Only the body posture changes.

This is an in-place edit, so the original crop and canvas are always preserved — ratio is ignored if you send it. Don't expect it to change the output framing; it won't.

Request body

Field	Type		Description
`toolId`	string	required	Always `"pose_angle_switch"`.
`images.user_photo`	string	required	URL of the existing on-model photo to re-pose.
`pose`	string	required	A catalog ID from GET /v1/poses. Required in practice — without it there's nothing to change the pose to.
