# Seedance 2.0 Token 计费

> 使用 doubao-seedance-2-0 系列模型提交并查询按 token 计费的视频任务（gogogotoken.ai）

`doubao-seedance-2-0` 与 `doubao-seedance-2-0-fast` 走 **ARK Token 计费**。提交与查询均使用 `/v1/video/generations`；任务完成后按 `data.data.usage.completion_tokens` **差额结算**。

费率分档见 [视频模型列表](/overseas/video-models)（BytePlus 官方 USD 价目）。

## 查询任务状态

```bash theme={null}
curl https://gogogotoken.ai/v1/video/generations/task_1234567890 \
