  • Alibaba Cloud Wanxiang video generation model
  • Supports three modes: Text-to-Video, Image-to-Video, and Reference Video (r2v)
  • Server automatically routes to the appropriate upstream model based on your request parameters
  • Supports 720p/1080p resolution, 5/10/15 second duration
  • Audio is always included in the generated output
Important Change: For better performance and cost control, we no longer support passing base64 image data directly in image_urls. Please use the Upload Image API first to upload images and get URLs, then call this endpoint.

​
Routing Logic

The server automatically selects the upstream model based on what parameters you provide:
Parameters ProvidedUpstream Mode
metadata.reference_urls (video URLs)Reference Video (r2v)
image_urls (image)Image-to-Video (i2v)
prompt onlyText-to-Video (t2v)

​
Authentication

​
Authorization
string
required
All endpoints require Bearer Token authenticationGet your API Key from the API Key Management PageAdd to request header:
