## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stablemesh-rigging-3b707829 -d '<json body>'
```

Example prompt: Take this 3D character mesh and automatically rig it with a skeleton and skinning weights so I can animate it — I want a full humanoid rig ready for animation.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
