用一个 PopNow API 密钥,就能在自己的代码里调用 Kling 2.1。下面列出要填的调用名、这个型号接受的每个输入字段、每次请求花多少积分,以及一段可以直接粘进终端运行的请求。

5.25 积分 每秒成片 ($0.0525)

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 5000 个字符Describe what happens after the opening frame: the action, the camera.
image_url必填string (uri)——Opening frame. The clip starts from this image. JPEG or PNG only.
last_image_url可选string (uri)——Optional closing frame the clip should end on. JPEG or PNG only.
resolution可选string720p720p, 1080pOutput resolution. Higher tiers cost more per second.
duration_seconds可选integer55, 10Output length: 5 or 10 seconds. Billed per second.
negative_prompt可选string—最多 500 个字符Things the clip should avoid, written as a short list.
guidance_scale可选number0.50 到 1How strictly the clip follows the prompt, from 0 to 1. Higher is more literal, lower gives the model more freedom.

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": "kling/2.1/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": "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
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=TASK_ID_FROM_CREATE_TASK" \
  -H "Authorization: Bearer $POPNOW_API_KEY"
