Transfer External URLs into ByteDance Assets

Material Library Usage Statement

Materials must be virtual human assets. Non-virtual-human materials should not be uploaded or stored in the library.

You must ensure that any uploaded virtual human materials meet the following conditions:

You legally own the materials and have full rights to use and dispose of them, and the materials do not contain any unauthorized third-party trademarks, logos, or other protected content;

The materials must not resemble or be substantially similar to any real person, and must not involve plagiarism, misappropriation, or infringement;

The materials must not contain any content that violates applicable laws, public order, or morality, or endangers national security.

Users are solely responsible for all materials they upload and use. Any disputes or legal risks arising from such materials shall be borne entirely by the user, and KIE reserves the right to remove or take action against such materials.

The /api/v1/playground/createAsset API helps users upload and transfer image, video, and audio files into ByteDance Asset storage.

This is especially useful when you want to bypass file source restrictions in non-generation workflows, such as face upload scenarios, where the downstream API requires a ByteDance-hosted asset instead of a direct external URL.

You can submit a resource URL together with its assetType, and the system will import and store it as a ByteDance asset.

Supported asset types include:

Image

Video

Audio

After the transfer is successful, the system will return an assetId. This assetId can then be reused in downstream APIs that require ByteDance asset input.

If you need to create and store a new asset, please go to Create ByteDance Asset.

Only URL-based uploads are supported. Base64 content is not supported.

Bearer Token

Provide your bearer token in the

Authorization

header when making requests to protected resources.

Example:

Authorization: Bearer ********************

curl --location --request POST 'https://api.kie.ai/api/v1/playground/createAsset' \ --header 'Authorization: Bearer <token>' \ --header 'Content-Type: application/json' \ --data-raw '{ "url": "http://example.com", "assetType": "Image" }'
