Retrieve an asset

This method retrieves details about the specified asset.

get/assets/{asset_id}

Path parameters

asset_idstring required

The unique identifier of the asset to retrieve.

Headers

x-api-keystring required

Your API key.

<Note title="Note"> You can find your API key on the <a href="https://playground.twelvelabs.io/dashboard/api-keys" target="_blank">API Keys</a> page. </Note>

Response

The asset has been successfully retrieved.

_idstring

The unique identifier of the asset.

method'direct' | 'url' | 'multipart'

Indicates how you uploaded the asset.

Values:

  • direct: Uploaded from your local file system
  • url: Uploaded from a publicly accessible URL
  • multipart: Uploaded using the multipart upload flow
status'failed' | 'processing' | 'ready'

Indicates the current processing status of the asset.

A newly uploaded asset starts in the processing status and transitions asynchronously to ready on success or to failed on error, typically within a few seconds to a few minutes. Poll the Retrieve an asset endpoint until the status is ready before you use the asset in downstream workflows.

Values:

  • processing: The asset is not yet usable. This can mean the upload is still in progress (for example, the platform is still fetching the file from a URL, or a multipart upload has not completed), or the upload has finished and the platform is validating the file. The technical_metadata field is omitted from the response.
  • ready: The platform validated the asset successfully, and the asset is ready to use.
  • failed: The platform could not process the file. The error field describes the reason, and the technical_metadata field may be partially populated.
filenamestring

The name of the file used to create the asset.

file_typestring

The MIME type of the asset file.

created_atstring date-time

The date and time, in RFC 3339 format ("YYYY-MM-DDTHH:mm:ssZ"), when the asset was created.
