请求体
application/json
视频生成模型名称
可用选项:
happyhorse-1.0-text-to-video 示例:
"happyhorse-1.0-text-to-video"
文本提示词，必填
长度限制：
- 中文：最多
2500个字符 - 非中文：最多
5000个字符 - 超长部分将被自动截断
提示词技巧：
- 鼓励使用详细分镜描述获得更好的多镜头叙事效果
- 例如：
第 1 个镜头 [0~3 秒] 全景：...； 第 2 个镜头 [3~6 秒] 中景：...
示例:
"一座由硬纸板和瓶盖搭建的微型城市，在夜晚焕发出生机。一列硬纸板火车缓缓驶过，小灯点缀其间，照亮前路。"
视频分辨率档位，默认为 720p
可选值：
720p：标准清晰度，此为默认值1080p：高清清晰度
计费提示： 分辨率档位直接影响计费，详见模型计费规则
可用选项:
720p, 1080p 示例:
"720p"
视频宽高比，默认为 16:9
可选值：
16:9（横屏）9:16（竖屏）1:1（方形）4:33:44:55:49:2121:9

必填范围:
3 <= x <= 15示例:
5
随机种子，默认随机
说明：
- 取值范围：
1~2147483647 - 固定 seed 可在调试 prompt 时降低参数变化的干扰，提升结果可复现性
必填范围:
1 <= x <= 2147483647示例:
42
任务完成后的 HTTPS 回调地址
回调时机：
- 任务完成（completed）、失败（failed）或取消（cancelled）时触发
- 在计费确认完成后发送
安全限制：
- 仅支持 HTTPS 协议
- 禁止回调到内网 IP 地址（127.0.0.1、10.x.x.x、172.16-31.x.x、192.168.x.x 等）
- URL 长度不超过
2048字符
回调机制：
- 超时时间：
10秒 - 失败后最多重试
3次（分别在失败后1/2/4秒重试） - 回调响应体格式与任务查询接口返回格式一致
- 返回 2xx 状态码视为成功，其他状态码触发重试
示例:
"https://your-domain.com/webhooks/video-task-completed"
