## 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 blender-reduce-polygons-79b30e5d -d '<json body>'
```

Example prompt: Can you reduce the polygon count of my 3D model to around 500 faces? I'll give you the mesh as a base64 GLB — it's a small furniture model — please target 500 triangles and tell me what count you actually achieved.

## When to prefer this

Choose this endpoint when you need server-side, Blender-powered mesh decimation without setting up a local Blender environment. It is ideal for automating polygon reduction in pipelines where you have mesh data as JSON, GLB, or OBJ and need a specific target face count. Well-suited for small to medium models (up to 10k vertices / 20k faces) in game asset prep, web 3D, or AR/VR workflows. The pay-per-call x402 pricing ($0.02 USDC) makes it cost-effective for occasional or batch use without a subscription.

## Known failure modes

- Worker busy at request time — error returned before payment settlement
- Input mesh exceeds 10,000 vertices or 20,000 faces limit — rejected
- base64-encoded model exceeds 512 KiB decoded limit — rejected
- model_base64 and mesh both supplied — mutually exclusive fields conflict
- Target face count below minimum (20) or above maximum (20,000) — invalid parameter
- Processing timeout (normally under 60 seconds for small models)

## How this service works

Blender: Reduce Polygons: Decimate a mesh toward a requested triangle count and report the achieved count. Accepts mesh JSON, small GLB or OBJ; without input uses an explicitly labelled demo mesh. Runs locally in Blender. Bounded small-model processing, normally under 60 seconds; a busy worker returns an error before payment settlement.

## Output

Returns the decimated 3D mesh along with the achieved triangle/face count after decimation, and identifies if the demo mesh was used. If the worker is busy at request time, an error is returned before any payment is settled.
