Querying Available Models

import requests
import os

def get_available_models():
    """Retrieve list of available models."""
    response = requests.get(
        "https://api.klingai.com/v1/models",
        headers={"Authorization": f"Bearer {os.environ['KLINGAI_API_KEY']}"}
    )
    return response.json()["models"]

models = get_available_models()
for model in models:
    print(f"Model: {model['id']}")
    print(f"  Name: {model['name']}")
    print(f"  Max Duration: {model['max_duration']}s")
    print(f"  Resolutions: {model['resolutions']}")
    print(f"  Price: ${model['price_per_second']}/second")
    print()

Model Selection Logic

def select_model(
    duration: int,
    resolution: str,
    quality: str = "standard",
    budget_per_second: float = 0.10
) -> str:
    """Select the best model for requirements."""

    # Duration constraints
    if duration > 30:
        return "kling-pro"

    # Quality requirements
    if quality == "premium" or resolution == "4k":
        if budget_per_second >= 0.20:
            return "kling-pro"
        return "kling-v1.5"

    # Budget optimization
    if budget_per_second < 0.10:
        return "kling-v1"

    # Default to enhanced
    return "kling-v1.5"

# Usage
model = select_model(duration=15, resolution="1080p", quality="high")
print(f"Recommended model: {model}")

Generation Types

Text-to-Video

def text_to_video(prompt: str, model: str = "kling-v1.5"):
    """Generate video from text prompt."""
    response = requests.post(
        "https://api.klingai.com/v1/videos/text2video",
        headers={"Authorization": f"Bearer {os.environ['KLINGAI_API_KEY']}"},
        json={
            "model": model,
            "prompt": prompt,
            "duration": 10,
            "aspect_ratio": "16:9"
        }
    )
    return response.json()

Image-to-Video

def image_to_video(image_url: str, motion_prompt: str, model: str = "kling-v1.5"):
    """Animate an image into video."""
    response = requests.post(
        "https://api.klingai.com/v1/videos/image2video",
        headers={"Authorization": f"Bearer {os.environ['KLINGAI_API_KEY']}"},
        json={
            "model": model,
            "image_url": image_url,
            "motion_prompt": motion_prompt,
            "duration": 5
        }
    )
    return response.json()

Video Extension

def extend_video(video_id: str, additional_seconds: int):
    """Extend an existing video (Pro only)."""
    response = requests.post(
        "https://api.klingai.com/v1/videos/extend",
        headers={"Authorization": f"Bearer {os.environ['KLINGAI_API_KEY']}"},
        json={
            "model": "kling-pro",
            "source_video_id": video_id,
            "extend_duration": additional_seconds
        }
    )
    return response.json()

Output

Successful execution produces:

• List of available models with capabilities
• Model recommendation based on requirements
• Understanding of pricing and tradeoffs

Error Handling
