Kling 3.0 API

Introduction

Kling 3.0 Motion Control takes one clear photo of a character (image_url) and a driving clip (video_url, 3 to 30 seconds) and re-plays the driving clip's moves, expressions and hand gestures on that character, keeping their face, outfit and setting from the photo. prompt is optional - use it for anything the driving clip does not show, such as the setting or the look.

Key features

One photo, one driving clip, the same performance twice

Record or license one driving clip - a dance, a walk, a gesture - and run it through as many character photos as you need. In our test the same driving clip's routine came back matched beat for beat on two different characters, each keeping their own face, clothing and background.

720p or 1080p

Motion Control does not go up to 4K.

Request parameters

Pricing

Prices are in credits, the same credits you use on the website (1 credit = $0.01). The hold is taken when the task is accepted and settled to the actual charge when it finishes; failed tasks are refunded.

For an exact number before you run, send the same body to POST /jobs/quote.

Use cases

Reuse one performance across characters

Choreograph or license a single driving clip once, then apply it to every character photo in a series - a dance routine, a product presenter's gesture set, a recurring greeting - without reshooting the motion each time.

Give a still character photo real, directed motion

Instead of describing motion in words and hoping for a specific gesture, Motion Control lets you show the exact motion once, as a driving clip, and apply it precisely.

Localize a performance to a new setting

Use the optional prompt to place the character in a different location than the driving clip's own background, while the motion itself stays identical.

Prompt guide & pro tips

Let the driving clip carry the motion

The prompt does not need to describe any movement - the driving clip already supplies it. Use it only for what the clip does not show, such as the room, the wardrobe detail, or the mood.

Keep the character photo clear and single-subject

A clear, full or half-body photo of one person, well lit and unobstructed, gives Motion Control the clearest match. A photo with the character partly hidden or at an unusual angle leaves more for the model to guess.

API quick start

Call the Kling 3.0 API in three steps

1. Create an API key. Sign in to PopNow and create a key in the API console. Keys start with sk-popnow- and use the same credits as the website.
2. Send the request. POST /jobs/createTask with model kling/3.0/character-animation and an input object that follows the parameter table. The response returns a task ID straight away.
3. Get the result. Poll GET /jobs/recordInfo with the task ID, or pass a callBackUrl and we post the result to it. Download the output links when the task succeeds.

# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.
export IDEMPOTENCY_KEY="$(uuidgen)"
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: $IDEMPOTENCY_KEY" \
  -d '{
  "model": "kling/3.0/character-animation",
  "input": {
    "prompt": "A slow aerial shot drifting over a misty pine forest at sunrise",
    "image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
    "video_url": "https://media.popnow.ai/effects/flower-bloom-1abd6efb.mp4",
    "resolution": "720p",
    "character_orientation": "video",
    "shot_type": "customize"
  }
}'

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.
TASK_ID="TASK_ID_FROM_RESPONSE"
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
  -H "Authorization: Bearer $POPNOW_API_KEY"

Replace the prompt and any links with your own. The API tab has the response, polling and callback reference.
