参数

字段	类型	默认值	取值范围	作用
`prompt`必填	`string`	—	—	Describe the intended subject, action, camera, light, sound, and constraints.
`aspect_ratio`可选	`string`	`adaptive`	16:9, 9:16, 4:3, 3:4, 1:1, 21:9, adaptive	Output frame ratio.
`resolution`可选	`string`	`720p`	480p, 720p	Output resolution.

`generate_audio`可选	`boolean`	`true`	—	Request synchronised output audio.
`enable_web_search`可选	`boolean`	`false`	—	Let the model search the web for information related to the prompt before rendering.
`seed`可选	`integer`	—	0 到 2147483647	Random seed. Omit to let the model pick one.
`return_last_frame`可选	`boolean`	`false`	—	Also return the clip’s final frame as a separate image.
`bitrate_mode`可选	`string`	`standard`	standard, high	Encoding bitrate of the delivered file: standard, or high for crisper detail and a larger file.
`watermark`可选	`boolean`	`false`	—	Add the model’s visible "AI generated" watermark to the video.

请求示例

这段请求原样就能运行，没写的字段都用默认值。运行前先把密钥放进环境变量 POPNOW_API_KEY。

POST /api/v1/jobs/createTask

curl -X POST "https://api.popnow.ai/api/v1/jobs/createTask" \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
