Wan 3.0 Pro API

About Wan 3.0 Pro

Wan 3.0 Pro delivers Alibaba's Wan 3.0 at 1080p, 2K or 4K. A native Wan 3.0 render tops out at 1080p, so the 2K and 4K tiers are enlarged from it: this is a high-resolution delivery tier built on Wan 3.0, not a separate Alibaba model. It is published as separate APIs — text-to-video, image-to-video, video-extend and reference-to-video — with generated audio and no platform filter on any endpoint.

Call it with the model name alibaba/wan-3.0-pro/text-to-video on POST /jobs/createTask, from 108 credits for a 5-second clip ($1.08). New accounts get 30 free credits to try it in the Playground first.

Introduction

Wan 3.0 Pro Text to video writes a shot from a prompt and delivers it at 1080p, 2K or 4K for 2 to 30 seconds, with generated audio in the same file. prompt is the only required field and accepts up to 20,000 characters. A native Wan 3.0 render tops out at 1080p, so the 2k and 4k tiers are enlarged from that render rather than drawn at those sizes. There is no 480p or 720p tier on this endpoint; Wan 3.0 covers those sizes.

Key features

Three delivery sizes from one native render

resolution takes 1080p (the default), 2k or 4k. The two larger tiers stretch what the model drew rather than drawing more, so they suit footage that will be cropped, tracked or projected, and they are only as good as the render underneath. Find the shot at 1080p first and treat 4K as a delivery step.

Prompt expansion starts switched on

On this family enable_prompt_expansion defaults to true. It fills out a thin brief, which is handy while you are still sketching, and it rewrites a detailed one. Once your prompt is a precise shot description, set the field to false so the wording you tuned is the wording that runs.

Adaptive frame unless you pin one

aspect_ratio defaults to adaptive, which lets the model choose the frame. Name 16:9, 4:3, 1:1, 3:4 or 9:16 when the delivery format is fixed: the fence example asks for 9:16 for a vertical frame, while the perfume, monochrome and tattoo examples all pin 16:9.

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

Fragrance and beauty spots under hard light

Specular fabric, one hard source and small fast particles break first when footage is enlarged, so inspect exactly those in a 2K or 4K delivery.

Fabric driven by one external force

Two examples direct clothing through a single force instead of describing how it sits. In the monochrome fashion film, three metres of silk chiffon in front of an industrial wind machine whips around the body and twists around one shoulder under a hard key against a black void. In the fence example, jet wash from a landing aircraft presses two people's clothes flat against them. Naming the force gives the fabric a cause to follow.

Prompt guide & pro tips

Explore at 1080p, then re-render the chosen seed

Find the shot at 5 seconds and 1080p with seed fixed, change one field per rerun, and only then send the same prompt and seed with resolution set to 4k. Changing resolution and wording in the same rerun makes it impossible to tell which one moved the result.

Write the shot, not a mood

Subject, one action, one camera move, then light and sound. The tattoo-parlour prompt is a good model: candles and one desk lamp as the only light, gloved hands shading a piece across the ribs, a wince, a slow breath and a grin over the shoulder, a buzzing machine, a very slow push-in. At 4K a vague brief is an expensive way to discover what you meant.

Name the sounds you want to hear

Sound is generated with the picture, so list its sources: the perfume spot asks for "low cello note and rain", the wind-machine film for "the roar of the fan and snapping cloth". Set generate_audio to false when a composer is scoring the spot.

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/text-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/text-to-video",
  "input": {
    "prompt": "A slow aerial shot drifting over a misty pine forest at sunrise",
    "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.
