# 1) Submit — returns { "task_uuid": "..." }

  -H "Authorization: Bearer YOUR_API_KEY" \

      "https://assets-public.namifusion.com/marketplace/images/2026-06-12/638e1ee18ac7.jpeg"
    ],
    "prompt": "Animate the subject with natural motion, a slow cinematic camera push-in, soft wind, stable anatomy, and consistent lighting.",

  }

What parameters does it take?

image (Input Image): required

last_image (Last Frame): optional

prompt (Prompt): required

duration (Duration): optional, default 5

resolution (Resolution): optional, default "480p"

prompt_extend (Prompt Extend): optional, default true

seed (Seed): optional

How do you write prompts for alibaba/wan-2.2-spicy/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. About $0.101 per typical run ($1 = 100 credits); the exact price varies with parameters like resolution or duration, and the playground shows the exact quote before you submit.
