右侧 Playground 可直接调试：在 Authorization 填 Bearer sk-your-api-key，填好 model / input.media / parameters 后发起请求。提交成功返回 task_id，轮询与下载见下方说明。

本页是 wan2.7-i2v（图生视频）的创建接口：给一张首帧图 + prompt，让画面动起来；可选传 driving_audio 让人像跟随音频做口型/节奏。完整异步流程见 Wan 概览。

• 音频驱动是 wan2.7-i2v 专属能力：HappyHorse 的 i2v 不支持 driving_audio，做对口型 / rap 必须用 wan2.7-i2v。
• input.media 必填，否则上游报 图生视频模型 ... 必须提供图片。媒体 url 必须是公网可直接 GET 的 https 链接。
• 创建请求走 /wan/api/v1/... 并带 X-DashScope-Async: enable，不要用 /v1/videos。

查询状态与下载视频

拿到 task_id 后，按以下三步查询状态并下载 mp4：

• 轮询 GET /v1/tasks/{task_id}（带 Authorization，查询不需要 X-DashScope-Async 头），每 5–10 秒一次（不要 < 3 秒），直到 status 变为 completed。
• 状态取值：submitted（排队）/ in_progress（生成中，progress 常停在 30% 属正常）/ completed（成功）/ failed（失败，看 error）。
• 下载：从响应的 result_url 直接 GET，不要带 Authorization 头（OSS 签名直链，带了反而 403）；result_url 默认 24 小时过期，务必尽快转存。

查询状态

curl "https://api.apiyi.com/v1/tasks/f8ca39a0-6f4b-4ec2-99bf-8b9649d946c4" \
  -H "Authorization: Bearer sk-your-api-key"

{
  "status": "completed",
  "progress": 100,
  "result_url": "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=...",
  "task_id": "f8ca39a0-6f4b-4ec2-99bf-8b9649d946c4"
}

# result_url 是 OSS 签名直链，下载时不要带 Authorization 头（带了反而 403）
curl -L -o out.mp4 "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=..."

TASK_ID="f8ca39a0-6f4b-4ec2-99bf-8b9649d946c4"
URL=$(curl -s "https://api.apiyi.com/v1/tasks/$TASK_ID" \
  -H "Authorization: Bearer sk-your-api-key" | jq -r '.result_url')
curl -L -o out.mp4 "$URL"   # 不带 Authorization

上面是「已有 task_id」的快捷查询/下载。完整轮询循环（含超时兜底）与 Python 客户端见 Wan 概览 · 异步调用流程。
