API 参考

Wan 视频 API 快速开始

API 使用和网页版相同的模型、价格和退款规则。每次生成都是一个异步任务:先提交,再轮询(或接收回调),直到视频生成完成。

1. 创建 API 密钥

登录后,系统会在「开始使用」页面自动为你创建第一个密钥。新账号赠送免费调用(限最低价参数)用于测试接入,之后可购买一次性积分包充值。

shell
export API_KEY="sk-..."

2. 提交任务

向 /videos/generations 发送 POST 请求和提示词,会立即返回任务 ID 和扣除的积分。

curl -X POST "https://api.wan3api.org/v1/videos/generations" \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{
  "model": "wan-3",
  "prompt": "A red fox runs through fresh snow at sunrise, slow motion, cinematic",
  "duration": 5,
  "resolution": "480P",
  "aspect_ratio": "16:9"
}'

3. 等待视频

每隔几秒请求 GET /tasks/:id,或传入 callback_url 由我们把完成的任务 POST 给你。大多数视频一到三分钟完成。

# Poll every few seconds until status is "succeeded" or "failed".
curl "https://api.wan3api.org/v1/tasks/$TASK_ID" \
  -H "Authorization: Bearer $API_KEY"

# Then download the video.
curl -L -o video.mp4 "$VIDEO_URL"

4. 下载视频

status 为 succeeded 时,video_url 就是 MP4 地址。文件已复制到我们的存储,不会像上游链接那样一小时后失效。
