# 1) Submit — returns { "task_uuid": "..." }
curl -X POST "https://www.namifusion.com/api/v1/marketplace/run/pixverse/pixverse-c1/image-to-video" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "input": {
    "prompt": "A cinematic portrait, dramatic rim light, shallow depth of field",
    "image": "https://example.com/input.jpg",
    "resolution": "540p",
    "duration": 5,
    "generate_audio_switch": false
  }
}'

What parameters does it take?

prompt (Prompt): required

image (Image): required

last_image (Last Image): optional

resolution (Resolution): optional, default "540p"

duration (Duration): optional, default 5

generate_audio_switch (Generate Audio Switch): optional, default false

seed (Seed): optional

How do you write prompts for Pixverse C1 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 $0.200 ($1 = 100 credits); the exact price varies with parameters like resolution or duration, and the playground shows the exact quote before you submit.
