Switch between them with one field

Both models sit behind the same endpoint, API key and polling flow, so testing one against the other is a one-line change:

curl -X POST "https://videogenapi.com/api/v1/generate" \
  -H "Authorization: Bearer $VIDEOGEN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "kling-3", "prompt": "A runner crosses a rain-soaked street at night, neon reflections, tracking shot", "duration": 8}'

Replace "kling-3" with "seedance-2" to run the same prompt on Seedance 2. Poll GET /api/v1/status/{generation_id} until the status is completed. Full details on the Kling 3 and Seedance 2 pages, and in the generate reference.
