Create embeddings for text, image, and audio

Note

This endpoint will be deprecated in a future version. Migrate to the Embed API v2 for continued support and access to new features.

This method creates embeddings for text, image, and audio content.

Ensure your media files meet the following requirements:

Audio files.
Image files.

Parameters for embeddings:

Common parameters:
- model_name: The video understanding model you want to use. Example: “marengo3.0”.
Text embeddings:
- text: Text for which to create an embedding.
Image embeddings: Provide one of the following:
- image_url: Publicly accessible URL of your image file.
- image_file: Local image file.
Audio embeddings: Provide one of the following:
- audio_url: Publicly accessible URL of your audio file.
- audio_file: Local audio file.

Notes

The Marengo video understanding model generates embeddings for all modalities in the same latent space. This shared space enables any-to-any searches across different types of content.
You can create multiple types of embeddings in a single API call.
Audio embeddings combine generic sound and human speech in a single embedding. For videos with transcriptions, you can retrieve transcriptions and then create text embeddings from these

Request

Request to create an embedding synchronously.

model_namestringRequired

The name of the model you want to use. The following models are available:

marengo3.0: Enhanced model with sports intelligence and extended content support.

The name of the model you want to use. The following models are available: - `marengo3.0`: Enhanced model with sports intelligence and extended content support.

textstringOptional

The text for which you wish to create an embedding.

Example: “Man with a dog crossing the street”

image_urlstringOptionalformat: "uri"

The publicly accessible URL of the image for which you wish to create an embedding. This parameter is required for image embeddings if image_file is not provided.

image_filefileOptional

The image file for which you wish to create an embedding as a local file. This parameter is required for image embeddings if image_url is not provided.

audio_urlstringOptionalformat: "uri"

The publicly accessible URL of the audio file for which you wish to creae an embedding. This parameter is required for audio embeddings if audio_file is not provided.

audio_filefileOptional

The audio file for which you wish to create an embedding as a local file. This parameter is required for audio embeddings if audio_url is not provided.

audio_start_offset_secdoubleOptionalDefaults to 0

Specifies the start time, in seconds, from which the platform generates the audio embeddings. This parameter allows you to skip the initial portion of the audio during processing. Default: 0.

Response

A text embedding has successfully been created.

model_namestring

The name of the video understanding model the platform has used to create this embedding.

text_embeddingobject

An object that contains the generated text embedding vector and associated information. Present when text was processed.

image_embeddingobject

An object that contains the generated image embedding vector and associated information. Present when image was processed.

audio_embeddingobject

An object that contains the generated audio embedding vector and associated information. Present when audio was processed.
