}查询任务状态
提交任务后,请使用统一查询接口查看进度并获取结果:获取任务信息
了解如何查询任务状态并获取生成结果
生产环境中,建议使用
callback_url 参数接收任务完成后的自动通知,而不是轮询状态接口。相关资源

通用 API
查询账户剩余积分
授权
所有 API 都需要通过 API Key 进行身份验证。
获取 API Key:
- 访问 API Key 管理页面 获取您的 API Key
使用方式: 添加到请求头:
x-api-key: YOUR_API_KEY
注意:
- 请妥善保管您的 API Key,不要与他人共享
- 如果怀疑 API Key 已泄露,请立即在管理页面重置
请求体
application/json
用于生成的模型名称,必填。
- 此接口必须使用
runway/gen-4-aleph
可用选项:
runway/gen-4-aleph Runway Gen-4 Aleph 模型的输入参数,用于视频到视频转换和风格迁移。

可选。用于接收任务完成通知的回调 URL。
- 生成完成后,系统会向该 URL POST 任务状态和结果
- 回调 payload 结构与任务状态查询接口返回的
data对象一致 - 您的回调接口应支持接收包含结果的 JSON POST 请求
- 成功接收后应返回 HTTP 200 状态码
示例:
"https://your-domain.com/api/callback"
响应
请求成功
响应状态码
