Animation is a separate workflow for eligible humanoid 3D Models and Asset Pack items. Each accepted animation request can create new output. If a response is lost, retry only with the same Idempotency-Key that you supplied on the first attempt.

​
Choose animations

Use GET /v1/animation-sets for curated sets or GET /v1/animation-options to search individual actions.

​
Animate a 3D Model

Call POST /v1/models/{modelId}:animate with either animationSetId or motionPrompt. When using a set, optionally choose animationActionIds. heightMeters controls character scale.

​
Animate Asset Pack items

Call POST /v1/asset-packs/{assetPackId}:animate. Use scope: "items" with itemIds to target selected eligible characters; otherwise the request applies to all eligible items.

​
Track and retrieve animation outputs

Poll the returned operation. Read the resulting animation resource, then use its /artifacts or /artifact-manifest route to retrieve clips and packaged files. Keep animation files with their source 3D Model or Asset Pack in your application’s asset record.
