# Blender: Convert GLB

> Blender: Convert GLB is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-16).

Converts mesh geometry and PBR materials (from JSON mesh, GLB, or OBJ) to a binary glTF (.glb) model using Blender, running locally.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-convert-glb-0dd5604a -d '<json body>'
```

Example prompt: Convert my OBJ geometry to a binary GLB file — it's a small model, about 800 vertices, with a blue color (#6688bb), roughness of 0.4, metallic at 0.2, and target it to around 500 faces at 256 resolution.

## When to prefer this

Use this endpoint when you need to convert raw mesh data (vertex/face JSON), OBJ geometry, or a small GLB into a standards-compliant binary glTF with PBR material settings, especially when you need Blender-quality geometry processing without running Blender locally. Ideal for small-to-medium models (under 512 KiB, under 10k vertices) where you want control over PBR parameters like metallic, roughness, and color at conversion time.

## Known failure modes

- Busy worker returns an error before payment settlement if the worker queue is full
- Input mesh exceeds 10,000 vertices or 20,000 faces — request rejected
- Base64 model exceeds 512 KiB decoded size limit
- model_base64 and mesh fields supplied simultaneously (mutually exclusive)
- Invalid hex color format for color field
- Blender processing timeout for complex geometry near limits
- Unsupported face polygon size (fewer than 3 or more than 16 indices per face)

## How this service works

Blender: Convert Glb: Convert geometry and supported PBR materials to a binary glTF model. 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 a binary glTF (.glb) file containing the converted 3D geometry with PBR material properties applied. The response identifies if the demo mesh was used instead of a user-supplied model. Processing is bounded to under 60 seconds for small models.
