How this service works
Auto-rig a humanoid 3D character. $0.20. Input models must be under 300,000 faces; run /api/remesh first when using high-poly generated models, then pass the completed remesh task ID.
Output
Returns a rigged 3D model with skeletal bone structure and skinning weights applied, formatted as JSON, enabling the model to be posed and animated in 3D software or game engines.
Example use cases
Rig game character for animation
“I have a humanoid character mesh for my indie game and I need you to automatically add a skeleton rig with skinning weights so I can start animating walk cycles and combat moves in Unity — can you make it animation-ready for me?”
Auto-rig uploaded avatar model
“A user just uploaded their custom 3D avatar to our platform and I need to rig it with bones and skinning weights so they can pose and animate it — go ahead and apply automatic skeletal rigging to the mesh.”
Prepare creature mesh for cutscene
“I've got a creature 3D model that I need to animate for a cinematic cutscene — please auto-rig it with a full skeleton and proper skinning weights so I can import it into Blender and start posing it.”
Technical details
Endpoint
POSThttps://stablemesh.dev/api/riggingWhen to prefer
Choose this endpoint when you need to automatically add skeletal rigging to a 3D model without a subscription or API key setup — ideal for one-off or infrequent rigging tasks where pay-per-request pricing ($0.2 USDC) is preferable to a recurring subscription. Best for agents that need to make 3D characters animation-ready on demand.
Side effects
- Invalid or malformed 3D mesh input returns an error
- Unsupported mesh format or topology causes processing failure
- Payment of 0.2 USDC not provided or rejected results in 402 Payment Required
- Complex or non-humanoid meshes may produce poor rigging quality
- Empty response schema suggests limited error detail may be returned
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| model_url | string | Public URL or data URI to a GLB file under 300,000 faces. If the model may exceed 300,000 faces, reduce it with /api/remesh before rigging. |
| height_meters | number | Character height in meters |
| input_task_id | string | ID of a completed Meshy task to rig. Rigging only accepts models under 300,000 faces; if the source model may exceed that limit, run /api/remesh first and pass the completed remesh task ID here. |
| texture_image_url | string | UV-unwrapped base color texture (PNG) |
