Kling AI API: How to Generate Videos with Kling via API

What is Kling AI?

Kling is Kuaishou's flagship AI video generation model. It supports both text-to-video and image-to-video generation, and is known for producing realistic motion, strong character consistency, and cinematic quality output.

The model is available in multiple quality tiers — standard for fast, cost-effective generation and pro for higher fidelity output with better detail and motion quality. Kling handles a wide range of scenes including human subjects, animals, landscapes, and abstract creative content.

How to Use the Kling API

Renderful provides a unified REST API for Kling and other video models. Send a single POST request to generate a video, then receive the result via webhook. Here's a working example:

curl -X POST https://api.renderful.ai/api/v1/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "kling/kling-video-o3-standard",
    "input": {
      "prompt": "A golden retriever running through autumn leaves in a park",
      "aspect_ratio": "16:9",
      "duration": 5
    },
    "webhook": "https://your-app.com/webhook"
  }'

Replace YOUR_API_KEY with your Renderful API key. The webhook URL will receive the completed video once generation finishes.
