Wan 3.0 Prime API

Introduction

Wan 3.0 Prime Image to video animates an opening frame for 2 to 30 seconds on the Prime render, with the same fields as Wan 3.0 Image to video. image_url is required and becomes the exact first frame; the prompt is optional and only needs to describe motion; last_image_url optionally fixes the final frame. Resolution is 480p, 720p or 1080p with 720p as the default, and audio is generated with the picture unless you set generate_audio to false.

Key features

Set and wardrobe from the still, action from the prompt

Since the frame supplies the look, the whole request can go on action and sound.

A fixed ending makes long changes safe

last_image_url makes the clip end exactly on a supplied image. The dance-floor example opens on an empty floor and ends on a supplied frame of a full room, 10 seconds at 1080p in 3:4 with audio off, so the model invents how the room fills rather than what it fills up to.

The frame's own shape by default

Leave aspect_ratio out and the clip keeps the opening frame's shape; a conflicting value crops. Source images can be JPEG, PNG without transparency, BMP or WEBP, 240 to 8000 pixels per side, up to 20 MB and no wider than 8:1. The closing frame follows the same file limits.

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 46 credits for a 5-second clip ($0.46).

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

Use cases

Fast action from a still

The beach example starts from a rider on horseback and asks for the canter to open into a gallop, sand and shallow water thrown up behind the hooves, and a fast tracking move alongside as she passes into a low sun. At that speed the opening frame stops helping, so the prompt carries the physics: what is thrown, in which direction, and how the camera keeps up.

One gesture with a pinned close

The masquerade example pins both ends — a supplied first and last frame of the same woman on the same marble staircase — and describes the entrance between them: she lifts away her gold mask, gathers her gown and walks down a few steps toward the camera while the masked guests raise their glasses. Because the closing still was made from the opening one, the gown, the chandelier and the crowd stay where they were. It runs 5 seconds at 720p with sound.

Prompt guide & pro tips

Approve the landing frame as a still first

When the ending matters, make the last frame before you render, from the same set and crop as the first.

Write sound as a list of sources

The sauna prompt ends with an "Audio:" line naming each source. That is more reliable than a mood word, and it ties each sound to the action that causes it. Set generate_audio to false, as the dance-floor example does, when the clip will be scored in the edit.

Settle short, then lengthen

Run the motion at 5 seconds with a fixed seed, then extend. Longer clips drift more in identity and geometry, and fast limb crossings at 30 seconds are where artefacts appear first. Keep enable_prompt_expansion at its default false so a precise motion brief is not rewritten before generation.

API quick start

Call the Wan 3.0 Prime 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-prime/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-prime/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.
