Migration guidance

Current route family	Current model scope	Video Studio replacement
`/api/v1/generate/video/`	`veo3_fast`, `veo3`, `kling_3_0`	`POST /api/v1/video-studio/generate/` with `model_slug` for all video models
`/api/v1/sora/*`	Sora-only	`POST /api/v1/video-studio/generate/` with `model_slug=sora_2*`
Model-specific landing docs	Single-model details	Use matrix + canonical API docs for shared contract behavior

Reference snippets

Legacy API-key flow

curl -X POST https://ulazai.com/api/v1/generate/video/ \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Luxury product teaser with moving camera",
    "video_model": "veo3_fast",
    "aspect_ratio": "16:9"
  }'

Canonical Video Studio replacement (API key)

fetch("https://ulazai.com/api/v1/video-studio/generate/", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_API_KEY",
  },
  body: JSON.stringify({
    model_slug: "veo31_fast",
    prompt: "Luxury product teaser with moving camera",
    aspect_ratio: "16:9",
    duration_seconds: 8
  })
});
