Example JSON Response (Simplified):

```

[ { "id": 42, "role": "button", "text": "Add to Cart", "bbox": { "x": 935, "y": 529, "w": 200, "h": 50 }, "visual_cues": { "cursor": "pointer", "is_primary": true, "color_name": "yellow" } }, { "id": 43, "role": "link", "text": "Privacy Policy", "bbox": { "x": 100, "y": 1200, "w": 80, "h": 20 }, "visual_cues": { "cursor": "pointer", "is_primary": false } } ]

```

This prototype builds on several open-source libraries:

MoviePy – video composition and rendering Pillow (PIL) – image processing and overlays

The demo app (MotionDocs) uses the public SentienceAPI SDK, generated from OpenAPI, which is the same interface used by the system internally.
