Wan 3.0 API

Introduction

Wan 3.0 Image to video animates a still you supply. image_url is used exactly as the first frame, so wardrobe, body, set and light direction come from the picture and the prompt only has to describe motion. The prompt is optional; without it the model animates the frame on its own. An optional last_image_url fixes the exact final frame. Clips run 2 to 30 seconds at 480p, 720p or 1080p, with generated sound on by default. It is the most literal of the modes: when the output has to match your wording, put the look in the image and spend the prompt on movement.

Key features

The opening frame sets the quality ceiling

Because the first frame is your image, its sharpness, lighting and composition are the upper limit of the clip. Sources can be JPEG, PNG without transparency, BMP or WEBP, 240 to 8000 pixels per side, no wider than 8:1 and at most 20 MB. Leave aspect_ratio out and the clip inherits the frame's shape; a conflicting ratio crops it.

A landing frame that is pinned, not suggested

last_image_url is not loose guidance: the clip ends exactly on that image, and it only works together with image_url. The bottle example passes the same packshot as both frames, so the bottle turns a quarter circle, lets a highlight travel across the glass and lands back on its starting angle with the label readable.

Long spans between two fixed moments

With both ends supplied, only the passage between them is generated. The rooftop example pins an open dance hold as the first frame and the bottom of a dip as the last, and the model fills the five seconds between them at 720p; the same two stills can bracket a much longer move, because duration_seconds reaches 30 on this endpoint.

Request parameters

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.

Each task is rounded up to whole credits, so one run at the lowest tier costs 34 credits for a 5-second clip ($0.34).

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

Use cases

Product turns that return to the hero angle

For packshots, supply the approved image as both first and last frame, lock the camera and describe a single movement. The bottle example uses one soft key from the left, no music (generate_audio set to false) and a fixed seed of 20260907, which makes it easy to rerun the same move after a small wording change and compare the two files.

Styled shots that follow the wording

When a garment, body or set has to appear exactly as approved, put it in the opening frame.

Prompt guide & pro tips

Describe what changes, not what is visible

Everything already in the frame is inherited, so redescribing it spends words that the motion needs. Say who or what moves, in which direction and how fast, then what the camera does: "The bottle rotates a quarter turn so the highlight travels across the glass, then returns to its starting angle. Locked camera, single soft key from the left, no music."

Prepare both frames as a matched pair

When you add last_image_url, make both images at the same crop and from the same set, and let the prompt explain how one becomes the other. The rooftop example pairs an opening frame of a couple in an open dance hold with a closing frame of the same couple, on the same rooftop and from the same camera position, at the bottom of a dip, and the prompt describes only the movement between them: he draws her in by the hand and lowers her into the dip while the camera stays locked.

Check the middle of the clip, not only the ends

A matching final frame does not prove a believable transition. Review the opening, middle and final moments for identity and geometry; if they drift, reduce the number of simultaneous movements before extending the duration. Settle the motion at 5 seconds, then lengthen, and keep enable_prompt_expansion at its default false so a detailed motion brief runs as written.

API quick start

Call the Wan 3.0 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/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/image-to-video",
  "input": {
    "prompt": "A slow aerial shot drifting over a misty pine forest at sunrise",
    "image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
    "resolution": "720p",
    "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.
