# Seedance 2.0 API Documentation

> Generate videos with the Seedance 2.0 model through the AI Studio API.

## Overview

Use the AI Studio API to create Seedance 2.0 generation tasks and query their status. The flow is asynchronous: create a task first, then poll the task endpoint with the returned `taskId`.

## Authentication

All requests require an API key in the `Authorization` header.

```http
Authorization: Bearer YOUR_API_KEY
```
