Wan 3.0 API guide: models, inputs, and your first video

The first decision in a Wan 3.0 API integration is what you want the model to work from: a written scene, a starting image, or a set of references. Alibaba Cloud documents Wan 3.0 as a video model that can generate up to 30 seconds in one pass and accept text, images, audio, video, and documents. 1

This guide explains those choices and how to prepare a first test. It describes upstream capabilities; Wan API's production endpoint and key access details will be published in its integration documentation. Model rates are listed on the pricing page. Each model below has its own specifications page.

Understand the model namesCopy heading link

Wan 3.0 is the model family. Comfy's official integration also lists wan3.0-video-prime as a selectable model. That confirms Prime is a distinct option, but a provider's model name alone does not establish its request schema, availability on another service, or the turnaround your application will get. 2

Prime and Pro are distinct variants: compare the resolution options and exact model identifier before choosing. Wan 3.0 and Prime support output up to 1080p; Pro and Prime Pro add 2K and 4K options.

For a useful comparison, send the same prompt and references at the same duration and resolution. Record completion time, cost, and whether the result meets your brief. A model label is not a substitute for that test.

Choose the input that matches your materialCopy heading link

Comfy documents three Wan 3.0 workflows: text to video, image to video, and reference to video. Its image workflow accepts a first frame and an optional last frame. Its reference workflow uses images, video, and audio, with tags such as @Image1, @Video1, and @Audio1 to describe each input's role. These names and tags belong to that integration; use your API provider's documented fields. 2

Alibaba's document input supports one file or link, with files up to 100 MB. The 50-page limit applies to PDF, DOCX, DOC, PPTX, PPT, KEY and PAGES files. A gateway may expose fewer input modes, so verify document support before building an upload flow around it. 1

Make the first test easy to evaluateCopy heading link

Start with a short clip and explicit output settings. For example, test a five-second product shot with a slow camera move and no spoken dialogue. This is a suggested test brief, not an API payload:

Set duration, resolution, aspect ratio, and audio intentionally wherever your provider exposes them. Comfy's current Wan workflow includes audio by default and offers 480p, 720p, and 1080p output. Those documented settings are a useful starting point, not a guarantee that every Wan endpoint exposes the same controls. 2

Review the result for the things your application actually needs: subject consistency, requested motion, audio, and usable composition. Alibaba identifies audio texture and accurate on-screen text as areas still being refined, so inspect generated speech and lettering before using a result in production. 1

Check the API contract before building the workflowCopy heading link

Before connecting a production application, confirm the exact model ID, authentication method, accepted media format, task submission and result retrieval flow, error behavior, and billing rules in the provider's documentation. Keep these details separate from the creative prompt.

For Wan API, start with the model overview. A successful authenticated request to the published endpoint should be your first integration milestone; the marketing page alone is not an API specification.
