# Create asset group (CreateAssetGroup)

> CreateAssetGroup — POST /api/v3/seedance

## Introduction

Create a virtual asset group. Regardless of the `GroupType` passed in, it is **always forced to** `AIGC`. Live person asset groups (`LivenessFace`) must use [CreateVisualValidateSession](/en/api-reference/endpoint/seedance-2.0-new/create-visual-validate-session).

Exceeding the per-user asset group limit returns `403` with `ResponseMetadata.Error.Code = "QuotaExceeded"`.
