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

The platform processes files up to 200 MB synchronously and sets the asset status to ready. For files larger than 200 MB, the platform processes the upload asynchronously. Check the asset status until it is ready before using the asset.

Workflow

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

(Optional) For files larger than 200 MB, check the asset status using the assets.retrieve method until status is ready before proceeding.

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.

File size: Up to 4 GB.

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.
