About this API
Sketchfab is a Paris-based 3D model sharing platform founded 2012, acquired by Epic Games in 2021 and integrated into Unreal Engine ecosystem. Dubbed "YouTube for 3D" — anyone can upload 3D models to share or sell. Business model: free uploads, subscription Pro for advanced features (private uploads, commercial license), marketplace takes commission. API use cases: (1) Game / VR / AR developers programmatically search models to integrate into products; (2) E-commerce turn furniture products into 3D models embedded in product pages for 360° viewing; (3) Museums embed scanned artifacts in official websites. Viewer widget is Sketchfab's killer feature — one-line iframe embed for interactive 3D preview, with AR mode (iPhone directly shows real-size object in your home).

FAQ
Can I use models commercially?+
Depends on model license. Free models have CC BY (requires attribution) or CC BY-NC (non-commercial) etc. Commercial models bought become commercial-usable.
How does AR work?+
Upload USDZ format models (Apple AR Kit compatible); iOS Safari auto-supports AR Quick Look for one-click AR preview.
