1 积分 = 0.01 美元。任务受理时先冻结可能的最高费用，完成后按实际用量结算、向上取整到整积分，多冻的退回；失败的任务不扣积分。想在运行前知道确切数字，先调 POST /api/v1/jobs/quote。

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 what happens after the opening frame: the action, the camera and the sound.
image_url必填string (uri)——Opening frame. The clip starts from this image and keeps its aspect ratio.
last_image_url可选string (uri)——Optional closing frame the clip should resolve to.
resolution可选string480p480p, 540p, 768p, 1080pOutput resolution.
duration_seconds可选integer53 到 15Requested output length in whole seconds, from 3 to 15.
loras可选array<object>[]最多 3 项Up to three LoRA weight files trained for MiniMax H3, each with its own strength.
seed可选integer—0 到 2147483647Random seed for controlled comparisons.

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。

示例里的 image_url 用的是 PopNow 的示例素材，换成你自己的公开 HTTPS 链接、上传文件或已保存的素材即可。

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": "minimax/h3-singularity-lora/image-to-video",
  "input": {
    "prompt": "He lands softly on the rooftop, laughs and turns toward the camera while the balloons sway in the evening breeze; slow push-in",
    "image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
    "duration_seconds": 5,
    "resolution": "480p"
  }
}'

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。
