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": "seedance-2", "prompt": "A runner crosses a rain-soaked street at night, neon reflections, tracking shot", "duration": 8}'

Replace "seedance-2" with "veo3" to run the same prompt on Veo 3 Fast. Poll GET /api/v1/status/{generation_id} until the status is completed. Full details on the Seedance 2 and Veo 3 Fast pages, and in the generate reference.
