API endpoint
Use UniAll AI's video generation endpoint:
```http POST /v1/videos/generations ```
The API is asynchronous, so your application should submit a job, store the returned task information, and poll or handle the resulting status according to your integration flow.
Example: image to video with audio
```bash curl -X POST "https://api.uniall.ai/v1/videos/generations" \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "kling-v3-pro-audio", "generation_mode": "image_to_video", "prompt": "A cinematic product reveal, soft studio lighting, smooth camera movement, premium commercial style.", "image_url": "https://example.com/reference.png", "duration": 5, "aspect_ratio": "16:9", "resolution": "pro", "video_count": 1 }' ```
Example: text to video
```json { "model": "kling-v3-pro-audio", "generation_mode": "text_to_video", "prompt": "A futuristic city street at night, reflective pavement, neon signs, slow cinematic dolly shot, natural ambient audio.", "duration": 6, "aspect_ratio": "9:16", "resolution": "pro", "video_count": 1 } ```
Example: first and last frame video
```json { "model": "kling-v3-pro-audio", "generation_mode": "first_last_frame", "prompt": "Create a smooth transition from the first frame to the final frame with realistic camera motion and coherent lighting.", "first_image_url": "https://example.com/first.png", "last_image_url": "https://example.com/last.png", "duration": 5, "aspect_ratio": "16:9", "resolution": "pro", "video_count": 1 } ```
Required fields by mode
| Mode | Required fields | |---|---| | `text_to_video` | `prompt`, `duration` | | `image_to_video` | `prompt`, `image_url`, `duration` | | `first_last_frame` | `prompt`, `first_image_url`, `last_image_url`, `duration` |
Although `duration` has a default in the UI, it is a required generation parameter in the API interface. Use an integer from 3 to 15.
Pricing and billing
Kling V3 Pro 有声 is billed per second. For the Pro Audio variant, the listed user price is **$0.11424 per second**. The displayed user price is approximately **¥0.82 / second**. Actual cost depends on the selected duration and resolution/audio variant.
Estimated example for `pro-audio`:
- 5-second video: 5 × $0.11424 = **$0.5712**
- 10-second video: 10 × $0.11424 = **$1.1424**
UniAll AI supports refund-on-failure behavior for this model. Failed generations are not retried automatically unless your own application implements a retry strategy.
Prompting tips
For better results, describe the subject, motion, camera language, scene style, and audio atmosphere in one prompt. For example:
> A close-up luxury perfume bottle on black marble, golden rim light, slow rotating camera, shallow depth of field, elegant commercial mood, subtle cinematic audio.
When using image-to-video, keep the prompt aligned with the image content. When using first/last frames, avoid asking for changes that conflict with the provided ending frame.
