Kling Python SDK for RunAPI

The Kling Python SDK is the language-specific package for Kling on RunAPI. Use this kling package for text-to-video, image-to-video, AI avatar, and motion control flows when your application needs JSON request bodies, task status lookup, and consistent RunAPI errors in Python.

This kling README is the Python package guide inside the public kling-sdk repository. For the repository overview, start at ../README.md; for model details, use https://runapi.ai/models/kling; for API reference, use https://runapi.ai/docs#kling; for SDK docs, use https://runapi.ai/docs#sdk-kling.

Install

pip install runapi-kling

Quick start

from runapi.kling import KlingClient

client = KlingClient()  # reads RUNAPI_API_KEY, or pass api_key="sk-..."

task = client.text_to_video.create(
    model="kling-3.0",
    prompt="A cat walking through a garden",
)
status = client.text_to_video.get(task.id)

avatar = client.ai_avatar.create(
    model="kling-ai-avatar-pro",
    prompt="A friendly host greeting the audience",
    source_image_url="https://example.com/portrait.jpg",
    source_audio_url="https://example.com/voice.mp3",
)

Use create when you want to submit a task and return quickly, get when you need the latest task state, and run when a script should create and poll until completion:

result = client.text_to_video.run(
    model="kling-3.0",
    prompt="A serene drone shot over a misty forest",
)
print(result.videos[0].url)

In web request handlers, prefer create plus webhook or later get polling so a worker is not held open.

RunAPI-generated file URLs are temporary. Download and store generated images, videos, audio, or other files in your own durable storage within 7 days; do not treat returned URLs as long-term assets.

Language notes

Pass parameters as keyword arguments and catch the runapi.kling error classes when building video jobs, workers, or scripts. The available resources are text_to_video, ai_avatar, image_to_video, and motion_control. Keep RUNAPI_API_KEY in the environment or your secret manager; never commit API keys or callback secrets.
