Kling 3.0 API Guide: Features, Pricing & Code

Kuaishou released Kling 3.0 on February 5, 2026, and it's a bigger jump than a typical version bump. Kling 2.6 topped out at 10-second clips in 1080p; Kling 3.0 generates natively at 4K, runs up to 60fps, extends to 15 seconds, and can plan out a multi-shot sequence the way a director would rather than producing one continuous take. It's live on Apiframe now, one key, one endpoint, the same billing and concurrency you're already using for every other model on the platform.

This guide covers what's actually new, then walks through generating with it, including pricing you can plan a budget around.

What's New in Kling 3.0

AI Director multi-shot storytelling. Kling 3.0 generates up to six distinct shots within a single clip, each with its own framing, camera movement, and narrative beat, while keeping spatial continuity automatically. One prompt returns something closer to an edited sequence than a single take, useful for anything that used to require stitching together separate generations.

Native synchronized audio. The model co-generates sound directly with the video, music, effects, and environmental audio, plus lip-synced dialogue across five languages (Chinese, English, Japanese, Korean, and Spanish), with multiple dialects and accents and distinct per-character voices. generate_audio defaults to true on Apiframe's endpoint, so this comes for free unless you turn it off.

Native 4K output. Video renders at true 4K (3840×2160) rather than being upscaled, with noticeably better handling of physics-heavy details like flowing water, fabric, and human anatomy.

Visual chain-of-thought reasoning. The model plans the sequence of events across the clip before generating the first frame, which is a large part of why multi-shot outputs hold together instead of drifting between shots.

Subject consistency and text preservation. Kling 3.0 locks a character's appearance and voice from a reference image or short clip, carrying identity across shots and scene changes, and keeps logos, signage, and on-screen text sharp and legible, a real advantage for product and branded content.

Getting Started on Apiframe

Kling 3.0 uses the same API key and billing as every other model on Apiframe, Flux, Veo 3.1, Seedance 2.0, and the rest, so it’s not a separate integration; it’s just one more model available through the integration you may already have. Requests are asynchronous: submit a job, then poll for the result or receive it via webhook. No Kuaishou account required.

If you're starting from scratch, sign up for free credits, grab an API key, and you’ll be generating within minutes. Full parameter reference lives in the Kling 3.0 docs, or try it directly in Apiframe Studio without writing any code first.

Full Code Walkthrough

1. Submit a generation request

bash
curl -X POST https://api.apiframe.ai/v2/videos/generate \
  -H "X-API-Key: afk_your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "a cinematic sunrise over a futuristic cityscape",
    "model": "kling-3.0",
    "klingParams": {
      "duration": 10,
      "mode": "pro",
      "aspect_ratio": "16:9",
      "generate_audio": true
    }
  }'

The same call in Python:

python
import requests

response = requests.post(
    "https://api.apiframe.ai/v2/videos/generate",
    headers={
        "X-API-Key": "afk_your_api_key_here",
        "Content-Type": "application/json",
    },
    json={
        "prompt": "a cinematic sunrise over a futuristic cityscape",
        "model": "kling-3.0",
        "klingParams": {
            "duration": 10,
            "mode": "pro",
            "aspect_ratio": "16:9",
            "generate_audio": True,
        },
    },
)
print(response.json())  # { "jobId": "...", "status": "QUEUED" }

Available klingParams fields: duration (3 to 15 seconds), mode (standard, pro, or 4k), aspect_ratio (e.g. "16:9"), start_image and end_image (URLs controlling the first and last frame), negative_prompt, generate_audio, and multi_prompt. Set mode to 4k to match Kling 3.0's native 4K spec directly, no upscaling step needed.

2. Multi-shot control with multi_prompt

This is the parameter that unlocks Kling 3.0's AI Director feature directly. Instead of one prompt describing a single shot, multi_prompt accepts a JSON array of timed prompts, letting you script out a sequence:

python
"klingParams": {
    "duration": 15,
    "mode": "pro",
    "generate_audio": True,
    "multi_prompt": '[{"time": 0, "prompt": "wide shot of a busy coffee shop, morning light"}, {"time": 5, "prompt": "close-up of a barista pouring latte art"}, {"time": 10, "prompt": "customer taking the first sip, smiling"}]'
}

3. Poll for the result

The submission returns a 202 with a jobId. Poll GET /v2/jobs/{id} until the status is COMPLETED, or supply a webhook_url instead:

python
import time

while True:
    job = requests.get(
        f"https://api.apiframe.ai/v2/jobs/{job_id}",
        headers={"X-API-Key": "afk_your_api_key_here"},
    ).json()
    if job["status"] in ("COMPLETED", "FAILED"):
        break
    time.sleep(5)

print(job["result"])  # { "videoUrl": "https://cdn2.apiframe.ai/videos/..." }

Average completion time is around 150 seconds, worth using webhooks over polling for anything running in production.

Pricing

Kling 3.0 bills per second of output, with the rate depending on mode and whether audio is included:

VariantCredits per second
Standard29
Standard + audio43
Pro39
Pro + audio58

At $0.01 per credit, a 5-second pro clip with audio costs 290 credits, about $2.90. A 15-second pro clip with audio costs 870 credits, about $8.70. A 10-second standard clip without audio runs 290 credits as well, about $2.90. Native 4K output is now available too via mode: "4k", matching Kling 3.0's full spec end to end.

Plan choice affects more than the per-second rate, it also sets your concurrency ceiling and monthly credit grant. The pricing page has the full breakdown, from the free tier (2 concurrent jobs) up through Enterprise (up to 500).

Use Cases

Multi-shot ad creative. Script a wide establishing shot, product close-up, and closing frame with multi_prompt instead of stitching together separate generations.

Product demos with consistent branding. Text and logo preservation across shots keeps product names and packaging legible through camera moves and scene changes.

Dialogue-driven short-form content. Native multilingual lip-sync makes two-character dialogue scenes viable without a separate audio pipeline, pair it with Veo 3.1 if you want to compare cinematic styles on the same project.

Localization. Regenerate the same clip with lip-sync in a different supported language for regional variants of one piece of creative.

FAQ

What's different between Kling 3.0 and Kling 2.6?

Kling 3.0 extends max duration from 10 to 15 seconds, moves from upscaled 1080p to native 4K, doubles frame rate to up to 60fps, adds native synchronized audio and multi-shot generation via multi_prompt, and expands lip-sync language support.

Does Kling 3.0 generate audio?

Yes, by default. It co-generates music, sound effects, ambient audio, and lip-synced dialogue directly with the video. Set generate_audio to false if you want silent output.

How long can Kling 3.0 clips be?

Anywhere from 3 to 15 seconds, set via the duration parameter.

Do I need a Kling AI account?

No. Apiframe manages access on your behalf, same key and billing as every other model on the platform.

Can I use Kling 3.0 alongside other models on Apiframe?

Yes, that's the point of the unified API. Generate with Kling 3.0, Seedance 2.0, or Veo 3.1 through the same key, same billing, same webhook setup.
