3. Poll the task status with the returned task_uuid and read the output URLs when completed.

# 1) Submit — returns { "task_uuid": "..." }
curl -X POST "https://www.namifusion.com/api/v1/marketplace/run/kwaivgi/kling-video-o1/image-to-video" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "input": {
    "image": "https://assets-public.namifusion.com/uploads/images/2026-04-14/5895345cd939.png",
    "last_image": "https://assets-public.namifusion.com/uploads/images/2026-04-14/c98e7d7d7c2e.png",
    "prompt": "Generate a dynamic video of a tranquil sunset scene transitioning into a starry night over the mountains, with realistic lighting and smooth motions.",
    "resolution": "1080P",
    "duration": 5,
    "sound": false,
    "shot_type": "intelligence"

How do you write prompts for Kling Omni Video O1 Image-to-Video?

1. Subject first: lead with the actor and action, then add environment, lighting and style ("an astronaut sprinting through a neon street in the rain, cinematic, shallow depth of field").

2. Concrete nouns beat stacked adjectives: "85mm portrait lens, golden-hour backlight" works far better than "very beautiful, ultra high quality".

3. Change one variable per iteration: pin the seed to reproduce a result, tweak a single phrase at a time so you know what actually moved the output.

4. State negatives positively: instead of "no blur", ask for "sharp focus, crisp details".

How much does it cost?

Pay-per-use in credits. A typical run costs about $0.560 ($1 = 100 credits); the exact price varies with parameters like resolution or duration, and the playground shows the exact quote before you submit.
