The Assets class provides methods to upload your media files to the platform. This method creates an asset that you can use in different workflows.

Workflow

1

Upload your file using the assets.create method. You receive the asset ID in the response.

2

For URL uploads larger than 200 MB, check the asset status using the assets.retrieve method until status is ready before proceeding.

3

What you do next depends on your use case:

  • For creating embeddings (videos, audio, images): Use the asset ID with the Embed API v2.
  • For entity search (images): Use the asset ID to create entities.
  • For search and analysis (videos): Index your asset using the asset ID.

Methods

Create an asset

Description: This method creates an asset by uploading a file to the platform. Assets are media files that you can use in downstream workflows, including indexing, analyzing video content, and creating entities.

Supported content: Video, audio, and images.

Upload methods:

  • Local file: Set the method parameter to direct and use the file parameter to specify the file.
  • Publicly accessible URL: Set the method parameter to url and use the url parameter to specify the URL of your file.

Upload limits:

  • Video and audio, local files: Up to 200 MB
  • Video and audio, public URLs: Up to 4 GB
  • Images: Up to 5 MB

Additional requirements depend on your workflow:

  • Search: Marengo requirements
  • Video analysis: Pegasus requirements
  • Entity search: Marengo image requirements
  • Create embeddings: Marengo requirements
Note

This method is rate-limited. For details, see the Rate limits page.

API Reference

Create an asset

List assets

Description: This method returns a list of assets in your account.

The platform returns your assets sorted by creation date, with the newest at the top of the list.

Function signature and example:

1list(
2 request?: TwelvelabsApi.AssetsListRequest,
3 requestOptions?: Assets.RequestOptions
4): Promise<core.Page<TwelvelabsApi.AssetDetail>>

Parameters

Provide one or more asset types. When you specify multiple types, the platform returns all matching assets. Values: image, video, audio.
filenamestringNoFilters the response to include only assets whose filename contains the specified string. The match is case-insensitive and supports partial matching.

Return value

Returns a Promise that resolves to a Page<TwelvelabsApi.AssetDetail> object that allows you to iterate through the paginated asset results. The AssetDetail interface extends Asset with additional fields for HLS streaming and thumbnail details.
