The Embed.V2 interface provides methods to create embeddings synchronously for multimodal content. This endpoint returns embeddings immediately in the response.

Note

This interface only supports Marengo version 3.0 or newer.

When to use this interface:

Create embeddings for text, images, audio, or video content
Get immediate results without waiting for background processing
Process audio or video content up to 10 minutes in duration

Do not use this interface for:

Audio or video content longer than 10 minutes. Use the embed.v2.create method instead.
