参数

字段	类型	默认值	取值范围	作用
`prompt`必填	`string`	—	最多 7000 个字符	Describe the picture, the action, the camera, the sound, and the boundaries for the shot.
`aspect_ratio`可选	`string`	`16:9`	16:9, 9:16, 1:1, 4:3, 3:4, 21:9	Output aspect ratio.

`duration_seconds`可选	`integer`	`5`	5 到 15	Requested output length in seconds.
`enable_prompt_expansion`可选	`boolean`	`false`	false	Accepted for compatibility only. This endpoint does not expand prompts, so the only allowed value is false.

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?wait=60

curl -X POST "https://api.popnow.ai/api/v1/jobs/createTask?wait=60" \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{
  "model": "minimax/h3/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,

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
