Wan 2.7 Spicy Image-to-Video API by Atlas Cloud

Wan 2.7 Spicy Image-to-Video

Wan 2.7 Spicy Image-to-Video turns a first-frame image into short cinematic motion with stable single-scene continuity, expressive subject movement, and strong temporal detail.

Highlights

• First-frame image-to-video: Provide one image URL or Base64 image as the first frame. This spicy variant does not accept video, last-frame, audio, or reference inputs.
• Prompt required: Use prompt to describe the subject motion, camera movement, and scene behavior.
• Stable single-scene prompting: Upstream prompt expansion is disabled internally for predictable single-scene output.
• 720P default with SR tiers: Defaults to 720P. Native 720P / 1080P and SR tiers 1080P-SR / 1440P-SR are shown in the UI. Lowercase aliases are accepted by the API for compatibility.
• Flexible short duration: Supports every integer duration from 2 to 15 seconds. The default is 5.
• Fixed negative prompt baseline: The default negative prompt reduces camera cuts, transitions, jump cuts, montage, and multi-shot output.

Parameters

Default negative_prompt:

camera cut, shot change, scene change, transition, jump cut, rapid editing, montage, multi-shot, multiple camera angles, perspective shift

How To Use

curl -X POST "https://api.atlascloud.ai/api/v1/model/generateVideo" \
  -H "Authorization: Bearer $AIP_API_KEY" \
  -H "Content-Type: application/json" \
  --data-raw '{
    "model": "atlascloud/wan-2.7-spicy/image-to-video",
    "image": "https://static.atlascloud.ai/media/images/db548fe3bd5cafa4ef7e0141d69c8566.jpeg",
    "prompt": "The woman turns toward the camera with a confident smile, hair moving naturally as the camera slowly pushes in.",
    "negative_prompt": "camera cut, shot change, scene change, transition, jump cut, rapid editing, montage, multi-shot, multiple camera angles, perspective shift",
    "resolution": "720P",
    "duration": 5,
    "seed": -1
  }'

Generation is asynchronous. Poll /api/v1/model/prediction/{request_id} for the final video URL.

SR Behavior

Native 720P and 1080P requests call the Wan 2.7 Spicy deployment directly. SR tiers use selector-gated VSR routes:

The native route explicitly excludes SR resolution values, so SR requests stay on the VSR path instead of randomly falling back to native dispatch.

Pricing

Pricing is per second before account or environment discounts.

Formula:

min(15, max(5, duration)) * (
  resolution == "1440P-SR" ? sku_1440p_sr :
  (resolution == "1080P-SR" ? sku_1080p_sr :
    (resolution == "1080P" ? sku_1080p : sku_720p))
)

Notes

• Use only one first-frame image for this spicy variant.
• Prompt expansion is fixed off internally for production traffic.
• 480p is not exposed for this model.
• Download the returned video_url promptly and store it in your own object storage if long-term access is required.
