## Usage Examples
### cURL
```bash
# Step 1: Start generation (async)
curl -X POST "https://api.atlascloud.ai/api/v1/model/generateVideo" \
-H "Authorization: Bearer $ATLASCLOUD_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "vidu/image-to-video-2.0",
"image": "https://static.atlascloud.ai/media/images/1745492812795806468_P4jFBxup.jpg",
"prompt": "Two colorful clowns dancing wildly in a busy street market, their exaggerated gestures and big smiles drawing attention. Vibrant stalls in the background, chaotic and joyful atmosphere, fast-paced movement, playful energy",
"duration": 4,
"movement_amplitude": "auto",
"seed": 0
}'
# Response will contain: {"code": 200, "data": {"id": "prediction_id", "status": "processing"}}
# Step 2: Poll for result (replace {prediction_id} with the id returned above)
curl -X GET "https://api.atlascloud.ai/api/v1/model/prediction/{prediction_id}" \
-H "Authorization: Bearer $ATLASCLOUD_API_KEY"
# Keep polling until status is "completed", "succeeded" or "failed"
# When completed, outputs will contain the generated content URL(s)
