One API for Multiple Video Models

Most video generation APIs lock you into a single model. When that model's quality plateaus or pricing changes, you rewrite your integration. Wireflow routes video generation through one REST endpoint with Kling 3 Pro, Veo 3.1, and Seedance behind it. Switching models means changing a node type in your workflow definition, not rebuilding your pipeline.

The API uses async execution by default. A POST request returns an executionId immediately; you poll for the result or register a webhook URL to receive the completed video. Per-node cost reporting shows exactly what each generation costs, so you can compare models on both quality and spend before committing to one in production.

What the Video Generation API Includes

🎬

Text-to-Video Generation

Send a text prompt, receive a generated video clip up to 10 seconds at 1080p resolution.

🖼️

Image-to-Video Animation

Upload a still image and a motion prompt to animate it into video with camera and subject movement.

🔄

Multi-Model Routing

Switch between Kling 3 Pro, Veo 3.1, and Seedance by changing one parameter in the request body.

📡

Webhook Delivery

Register a callback URL and receive the finished video as a webhook POST instead of polling.

💰

Per-Node Cost Reporting

Every execution returns a cost breakdown by model and resolution so you can track spend per request.

🔗

Pipeline Chaining

Chain image generation, upscaling, and video nodes into one API call that executes sequentially.

More Than Just Video Generation API

Production-Ready Video Pipeline

Run video generation at scale with async execution, retry logic, and rate limiting built into the endpoint. Build programmatic video generation without managing GPU infrastructure.

Production-Ready Video Pipeline

Kling 3 Pro Integration

Access Kling 3 Pro for 1080p image-to-video with physics simulation, camera control, and native audio sync. Follow the Kling API tutorial to get started.

Kling 3 Pro Integration

Visual Prototyping First

Design your video pipeline on a drag-and-drop canvas before writing a single line of code. Chain generation with the content generation API for end-to-end automation.

Transparent Model Pricing

Every API response includes the cost per node so you can compare Kling, Veo, and Seedance side by side. See real Veo 3.1 API pricing examples for benchmarks.

Multi-Model Video Output

Run the same prompt against multiple video models in one workflow to compare quality and speed. Access Kling Video 3 and Veo 3.1 from the same Bearer token.

FAQs

What is a video generation API?
A video generation API is an HTTP endpoint that accepts text prompts or images and returns AI-generated video clips. Developers integrate it into apps, websites, or automation pipelines to create video content programmatically.
Which video models does the Wireflow API support?
The API currently supports Kling 3 Pro, Google Veo 3.1, and ByteDance Seedance 2.0. You switch models by changing a parameter in the request body without modifying your integration code.
How much does video generation cost per API call?
Costs vary by model and duration. Kling 3 Pro runs approximately $0.30 to $1.00 per clip, Veo 3.1 starts at $0.03 per second, and Seedance 2.0 Fast starts at $0.09 per second. Every response includes the exact cost.
Can I generate video from a still image via the API?
Yes. Send a POST request with an image URL and a motion prompt to the image-to-video endpoint. The API supports Kling 3 Pro and Veo 3.1 for image-to-video animation with camera and subject control.
How does async video generation work?
The API returns an executionId immediately after your POST request. You either poll the status endpoint until the video is ready, or register a webhook URL that receives the completed video automatically.
Is there a free tier for the video generation API?
Wireflow offers a free plan with limited executions per month. The free tier includes access to all video models so you can test quality and integration before scaling up to a paid plan.
Can I chain video generation with other AI models?
Yes. Build a workflow that connects text-to-image, upscaling, and video generation nodes. The API executes the full pipeline in sequence and returns the final output as one response.
What video formats and resolutions are supported?
Output is MP4 at up to 1080p depending on the model. Kling 3 Pro supports clips up to 60 seconds, Veo 3.1 outputs 4K at 60fps, and Seedance produces 1080p clips up to 15 seconds.
