Kling 3.0 Turbo API

Introduction

Kling 3.0 Turbo Text to video turns a written scene into a clip of 3 to 15 whole seconds, at 720p or 1080p, with sound generated in the same pass. There is no silent mode on this endpoint: describe the dialogue and ambient sound you want in the prompt and they render along with the picture.

Key features

Sound is not optional, and that's the point

Every clip that comes off this endpoint carries a generated soundtrack: dialogue you put in quotes renders as spoken lines, and any ambient sound you name - music, footsteps, traffic - comes back mixed with the picture. In our tests, spoken lines matched the prompt word for word on every clip we ran. There is no field to turn audio off; for a silent 1080p clip, use Kling 2.5 Turbo instead.

One continuous take, no shot-cutting field

This endpoint has no multi-shot setting, so every clip plays as a single unbroken take. Write one clear action from start to finish - a dance, a sprint and a jump, a turn toward camera - rather than several beats you want stitched together.

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

Dialogue scenes for shorts and reels

Two people talking, laughing or trading a line works well here, since the audio comes back synced to the picture instead of dubbed on afterward. A kitchen scene we tested had the spoken line, the background music and the sound of a pot bubbling all arrive in the same file, with no separate audio pass needed before posting.

Action and movement clips with matching sound

Parkour, dance and other physical action come with footsteps, impacts and breathing built into the same file as the motion, with no separate foley pass to add.

Quick turnaround social clips that need sound from the start

Because audio is generated in the same pass as the picture, this endpoint suits any short clip destined straight for a feed or a reel, where waiting for a separate sound-design step would slow down the post.

Prompt guide & pro tips

Write the shot in the order it happens

Structure the prompt as subject, action, camera, then sound. The kitchen-salsa prompt is a workable template: who's dancing and what they're wearing, what they do (spins, bumps the counter), the camera (medium shot, gentle handheld), then the sound (music, laughter, the pot bubbling).

Match the sound to the action, not just the mood

Name sounds that are caused by something in frame - footsteps on concrete, a bubbling pot, a scooter engine - rather than a generic mood track. In our tests, sound tied to a visible action rendered more consistently in sync with the picture than an ambient cue with nothing in frame to produce it.

API quick start

Call the Kling 3.0 Turbo 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-turbo/text-to-video 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-turbo/text-to-video",
  "input": {
    "prompt": "A slow aerial shot drifting over a misty pine forest at sunrise",
    "aspect_ratio": "16:9",
    "resolution": "720p",
    "duration_seconds": 5
  }
}'

# 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.
