# List async embedding tasks

GET https://api.twelvelabs.io/v1.3/embed-v2/tasks

This method returns a list of the async embedding tasks in your account. The platform returns your async embedding tasks sorted by creation date, with the newest at the top of the list.

* Embeddings are stored for seven days.
* When you invoke this method without specifying the `started_at` and `ended_at` parameters, the platform returns all the async embedding tasks created within the last seven days.

Reference: https://docs.twelvelabs.io/api-reference/create-embeddings-v2/list-async-embedding-tasks

## Authentication

### MediaEmbeddingTaskDocumentEmbedding

An object containing the metadata associated with the embedding. Present only for `document` tasks created with Marengo 3.5.

- `metadata` (DocumentEmbeddingMetadata, optional) — An object containing metadata associated with the embedding. Only Marengo 3.5 returns this object.

### MediaEmbeddingTaskImageEmbedding

An object containing the metadata associated with the embedding. Present only for `image` tasks created with Marengo 3.5.
