设置了 callBackUrl,我们会把完成的任务发给你。先用原始请求体校验签名,再信任它。
上传本地文件
cURL
curl -X POST https://api.popnow.ai/api/v1/common/upload-url \

-d '{"contentType": "image/png", "bytes": 482113}'
# PUT the file bytes to data.uploadUrl with every header in data.headers, then commit it:
curl -X POST https://api.popnow.ai/api/v1/files/$FILE_ID/commit \

# The commit returns a popnow://f/... reference. Put it in any image, video or

公开的 https 链接可以直接用。本地文件要先经过 upload-url 和 commit。

API 快速上手
三步调用 Wan 2.6 Plus API
创建 API 密钥. 登录 PopNow,在 API 控制台创建密钥。密钥以 sk-popnow- 开头,API 调用使用独立的美元余额。
发送请求. 向 POST /jobs/createTask 发请求,model 填 alibaba/wan-2.6-plus/image-to-video,input 按参数表填写。响应会立刻返回任务 ID。
取回结果. 用任务 ID 轮询 GET /jobs/recordInfo,或者传 callBackUrl,结果会推送到这个地址。任务成功后下载输出链接。
