StableMesh

Pay-per-request AI 3D generation. No API keys. No subscriptions.

How it works

1POST to create a 3D generation task — pay $0.12–$1.20 USDC on Base, Solana, or Tempo
2Poll the task via GET until status: "SUCCEEDED"
3Download your 3D model (GLB, FBX, OBJ, STL, USDZ)

Example

Create task

POST /api/text-to-3d
{
  "mode": "preview",
  "prompt": "a medieval castle on a hill",
  "ai_model": "meshy-6"
}

Response

{
  "result": "task_abc123"
}

Poll until complete (SIWX auth)

GET /api/text-to-3d/task_abc123

{
  "id": "task_abc123",
  "status": "SUCCEEDED",
  "progress": 100,
  "model_urls": {
    "glb": "https://assets.meshy.ai/...",
    "fbx": "https://assets.meshy.ai/...",
    "usdz": "https://assets.meshy.ai/..."
  }
}
