参数

字段	类型	默认值	取值范围	作用
`prompt`必填	`string`	—	最多 2500 个字符	Describe the scene, the action and the camera. With sound on, add dialogue in quotes and the sounds you want.
`aspect_ratio`可选	`string`	`16:9`	16:9, 9:16, 1:1	Output aspect ratio.
`resolution`可选	`string`	`720p`	720p, 1080p, 4k	Output resolution. Higher tiers cost more per second.
`generate_audio`可选	`boolean`	`false`	—	Generate a native soundtrack (voices, effects, ambience) with the picture. Audio costs more per second.
`duration_seconds`可选	`integer`	`5`	3 到 15	Output length in whole seconds, from 3 to 15. Billed per second.
`shot_type`可选	`string`	`single`	single, multi, customize	single keeps one continuous shot; multi lets the model cut the prompt into several shots on its own; customize follows the shot list you give in multi_prompt.
`multi_prompt`可选	`array<object>`	—	最多 6 项	Shot list for shot_type customize: one entry per shot, in order, each with its own prompt and length in seconds. The lengths must add up to duration_seconds.

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" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{
  "model": "kling/o3/text-to-video",
  "input": {
    "prompt": "A paper boat drifts down a rain-soaked street at dusk, neon signs reflecting in the water, slow tracking shot at ground level",
    "duration_seconds": 5,
    "generate_audio": false,
    "resolution": "720p"
  }
}'

响应里会立刻带回 taskId。之后用 GET /api/v1/jobs/recordInfo 取结果，或者在请求里加上 callBackUrl 等通知。

GET /api/v1/jobs/recordInfo
