3d AI Studio API

3D AI Studio API Skill

Programmatic access to 3D AI Studio: text-to-3D, image-to-3D, AI image generation, 3D tools (convert, render, repair, optimize, bake), and the miniature figurine flow.

Quick Start

Environment Setup

Set your API key in .env:

3D_AI_STUDIO_API_KEY=your_api_key_here

Core Pattern — All Operations Are Async

Every generation or tool request returns a task_id. Poll status until FINISHED.

# 1. Submit a request → get task_id
python scripts/3d_api_client.py tencent-rapid --prompt "a wooden chair" --enable-pbr

# 2. Poll status
python scripts/3d_api_client.py status --task-id <task_id>

# 3. Download results when FINISHED
python scripts/3d_api_client.py download --task-id <task_id> --output-dir ./results

Or use --wait to poll automatically:

python scripts/3d_api_client.py tencent-rapid --prompt "a wooden chair" --enable-pbr --wait --output-dir ./results

Authentication

Bearer token from environment variable 3D_AI_STUDIO_API_KEY.

Authorization: Bearer <your_api_key>

Error Codes

Workflow Example — Full Miniature Pipeline

# 1. Check balance
python scripts/3d_api_client.py balance

# 2. Create miniature with auto-polling
python scripts/3d_api_client.py miniature \
  --image ./photo.jpg \
  --preset v3_miniature_human_full_body \
  --edition default \
  --scale h0 \
  --wait \
  --output-dir ./my_miniature
# → Downloads styled image, GLB, and scaled GLB (H0 1:87)

Implementation Notes

• All endpoints output GLB by default; use the Convert tool for OBJ/FBX/STL/PLY
• Result URLs expire after 24 hours — download promptly
• Poll every 10 seconds for generation tasks (3–8 min typical)
• The --wait flag polls automatically and downloads on completion
• Images passed as --image are auto-encoded to base64 by the client
• SKILL.md is the agent-facing reference; see references/api_reference.md for full endpoint details
