Kling API

Model Page: Kling API

Community model card for calling Kling through a REST API.

This repo documents the kling-3.0 model as exposed by Apiframe: Kuaishou's Kling Video 3.0, text-to-video and image-to-video, 3–15s, optional native audio, start/end frame control. Related ids on the same endpoint: kling-3.0-omni, kling-3.0-motion-control.

This repository does not host weights. Kling is a closed model. Inference runs remotely.

How to use

pip install requests

import os
import time
import requests

API = "https://api.apiframe.ai/v2"
headers = {
    "X-API-Key": os.environ["APIFRAME_API_KEY"],
    "Content-Type": "application/json",
}

job = requests.post(
    f"{API}/videos/generate",
    headers=headers,
    json={
        "model": "kling-3.0",
        "prompt": "a cinematic sunrise over a futuristic cityscape",
        "klingParams": {
            "duration": 5,
            "mode": "pro",
            "aspect_ratio": "16:9",
            "generate_audio": True,
        },
    },
).json()

while True:
    result = requests.get(f"{API}/jobs/{job['jobId']}", headers=headers).json()
    if result["status"] in ("COMPLETED", "FAILED"):
        break
    time.sleep(2)

print(result.get("result"))

result["videoUrl"] is the CDN URL. Pass webhookUrl on the generate call if you do not want to poll.

Image-to-video

import os
import requests

headers = {
    "X-API-Key": os.environ["APIFRAME_API_KEY"],
    "Content-Type": "application/json",
}

requests.post(
    "https://api.apiframe.ai/v2/videos/generate",
    headers=headers,
    json={
        "model": "kling-3.0",
        "prompt": "slow push in, steam rising from the cup",
        "klingParams": {
            "start_image": "https://example.com/frame.jpg",
            "duration": 5,
            "mode": "pro",
            "aspect_ratio": "16:9",
        },
    },
)

Swap model for kling-3.0-omni (reference images/video) or kling-3.0-motion-control (transfer motion from a clip onto a character).
