Wan 3.0 Pro API

Introduction

Wan 3.0 Pro Image to video animates an opening frame and delivers the clip at 1080p, 2K or 4K for 2 to 30 seconds. image_url is the only required field and is used exactly as the first frame, so wardrobe, body, set and light come from your still; the prompt is optional and should carry motion and camera only. last_image_url optionally fixes the exact final frame, and it works only together with image_url. Audio is generated with the picture unless you switch it off.

Key features

A 4K render cannot sharpen a soft still

The opening frame is the quality ceiling of the shot, and the 2k and 4k tiers enlarge a native 1080p render rather than drawing new detail. A soft or low-resolution source stays soft at 4K. Supply a JPEG, PNG without transparency, BMP or WEBP of 240 to 8000 pixels per side, up to 20 MB and no wider than 8:1, as sharp as you have.

Both ends pinned for edit-ready masters

The bottle example sends the same packshot as image_url and last_image_url at 4k, with prompt expansion and audio switched off and a fixed seed of 5512090. The bottle rotates a quarter turn so the highlight travels the length of the glass and returns to its opening angle, producing a master whose label stays readable when an editor pushes in digitally.

Framing follows the source by default

aspect_ratio defaults to adaptive, which follows the opening frame. Pin 16:9, 4:3, 1:1, 3:4 or 9:16 only when the delivery format is fixed. None of the four published examples sets a ratio, so each clip keeps the shape of its source image.

Pricing

Prices are in credits, the same credits you use on the website (1 credit = $0.01). The hold is taken when the task is accepted and settled to the actual charge when it finishes; failed tasks are refunded.

For an exact number before you run, send the same body to POST /jobs/quote.

Use cases

Long journeys with an approved payoff

The summit example supplies the foot of the mountain as image_url and the summit as last_image_url, then renders 10 seconds at 4K with the prompt covering only the climb between them. A long ascent is where an unpinned ending drifts; fixing the landing frame lets you approve the payoff as a still before paying for a 4K render.

Wardrobe held in the frame

It renders 5 seconds at 2k.

Prompt guide & pro tips

Use the prompt for motion and camera only

Prompt expansion is on by default on this family and will rewrite a detailed motion brief, so set enable_prompt_expansion to false once your wording is precise, as the bottle example does. Then say who moves, how far and how fast, and what the camera does. The prompt accepts up to 20,000 characters, but one clear action moves the result more than a long list.

Approve at 1080p, then render large

Settle framing and motion at 5 seconds and 1080p with a held seed; a rerun that changes both resolution and seed changes two things at once. When both frames are approved and the motion reads correctly, re-send the same body at 2k or 4k. Durations run 2 to 30 whole seconds, or -1 to let the model pick the length.

Inspect enlarged detail in the delivered file

In a 2K or 4K file, check the areas an enlargement stretches first: label text, hard specular highlights, hair and skin texture.

API quick start

Call the Wan 3.0 Pro API in three steps

1. Create an API key. Sign in to PopNow and create a key in the API console. Keys start with sk-popnow- and use the same credits as the website.
2. Send the request. POST /jobs/createTask with model alibaba/wan-3.0-pro/image-to-video and an input object that follows the parameter table. The response returns a task ID straight away.
3. Get the result. Poll GET /jobs/recordInfo with the task ID, or pass a callBackUrl and we post the result to it. Download the output links when the task succeeds.

# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.
export IDEMPOTENCY_KEY="$(uuidgen)"
curl -X POST https://api.popnow.ai/api/v1/jobs/createTask \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY" \
  -d '{
  "model": "alibaba/wan-3.0-pro/image-to-video",
  "input": {
    "image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
    "resolution": "1080p",
    "aspect_ratio": "adaptive",
    "duration_seconds": 5
  }
}'

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.
TASK_ID="TASK_ID_FROM_RESPONSE"
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
  -H "Authorization: Bearer $POPNOW_API_KEY"

Replace the prompt and any links with your own. The API tab has the response, polling and callback reference.
