How to Use the Atlas Cloud Asset Library for Seedance 2.0

The Asset Library for Seedance 2.0 and 2.0-Fast provides a structured method for incorporating reference media, such as images, videos, and audio, into video generation workflows by registering files with a stable ID rather than passing raw media with each call. The process involves three cURL calls: registering an asset via a public URL, polling until the asset status is Active, and then referencing it in generation requests. This system is essential for video and audio workflows, as these media types must be pre-registered and cannot be passed inline, unlike images. The library requires media to be accessible via a public URL, not through base64 or data URLs, and it offers lifecycle management capabilities, including renaming, trashing, and restoring assets. The guide also distinguishes between the Asset Library's management console and the separate host for video generation requests, emphasizing the need for proper validation of input files to avoid errors during registration.
