Thrixel API
Generate, refine, and export 3D models programmatically.
The Thrixel API turns text prompts and reference images into production-ready 3D models through a simple REST API. You submit a request, poll (or stream) until it's ready, then download the result in GLB, FBX, OBJ, STL, or USDZ.
Where to start
- Getting Started: base URL, authentication, rate limits, and a quickstart.
- MCP Server: drive all of this from Claude Code, Codex, or Gemini.
Generate 3D: pick the engine that fits your object:
- Auto - let Thrixel pick Architect or Sculptor for your prompt.
- Architect: editable, multi-part models (hard-surface, props, structured objects).
- Sculptor: dense, organic meshes (characters, creatures, photoreal forms).
- Upload a mesh: bring your own GLB into the pipeline.
- Image Hub: generate 2D reference images, then feed them to either engine.
Refine: improve any result:
- Edit: natural-language edits, optionally scoped to specific parts.
- Detailer & Texture: high-resolution detailing and texture generate/rebake.
- Remesh: re-decimate to a new triangle count.
Operate & guides:
- Writing Prompts: what works and what doesn't, for users with no 3D background.
- Job Status: polling, streaming (SSE), and submission listing.
- Download: get the model out in GLB, FBX, OBJ, STL, or USDZ.
- Projects & Sources: group submissions, attach style references, rename/archive/pin.
