How to Use the Wan 3.0 Prime API: Omni Reference integration guide (2026)

Wan 3.0 Prime is an Omni Reference model by Alibaba: Supports multimodal references including multiple images, video, and audio to generate videos with rich motion and synchronized audio-visual effects. Accurately preserves the appearance, motion characteristics, and visual style of referenced subjects, while supporting flexible combinations of references for versatile content creation and shot control. On NamiFusion you can try it in the playground (exact quote shown before you submit), then call it through one unified REST API — a typical run costs about $1.25.

TL;DR

· Task type: Omni Reference, provided by Alibaba

· Pricing: about $1.25 per typical run ($1 = 100 credits), pay-as-you-go

· Getting started: playground (exact quote before submit) → create an API key → one POST request

· Tunable parameters: 12 (see the table below)

· No platform watermark; commercial use allowed (per the Terms of Service)

What can you build with Wan 3.0 Prime?

Content automation: wire this model into your workflow and call it on demand through one unified API.

How do you call this API?

1. Sign up on NamiFusion and create a key on the API Keys page (signup bonus credits can only be used on selected models).

2. Submit a task with the cURL example below, passing your key as a Bearer token.

3. Poll the task status with the returned task_uuid and read the output URLs when completed.

# 1) Submit — returns { "task_uuid": "..." }
curl -X POST "https://www.namifusion.com/api/v1/marketplace/run/alibaba/wan-3.0-prime/video" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "input": {
    "resolution": "1080P",
    "aspect_ratio": "adaptive",
    "duration": 5,
    "generate_audio": true,
    "enable_thinking": false
  }
}'

# 2) Poll until status is "completed", then read the output URLs
curl "https://www.namifusion.com/api/v1/marketplace/run/tasks/TASK_UUID" \
  -H "Authorization: Bearer YOUR_API_KEY"

How do you write prompts for Wan 3.0 Prime?

1. Subject first: lead with the actor and action, then add environment, lighting and style ("an astronaut sprinting through a neon street in the rain, cinematic, shallow depth of field").

2. Concrete nouns beat stacked adjectives: "85mm portrait lens, golden-hour backlight" works far better than "very beautiful, ultra high quality".

3. Change one variable per iteration: pin the seed to reproduce a result, tweak a single phrase at a time so you know what actually moved the output.

4. State negatives positively: instead of "no blur", ask for "sharp focus, crisp details".

How much does it cost?

Pay-per-use in credits. A typical run costs about $1.25 ($1 = 100 credits); the exact price varies with parameters like resolution or duration, and the playground shows the exact quote before you submit.
