Prism API

Generate high-quality videos with rich animations and visuals

Overview

The Prism API generates high-quality videos with rich animations and visual effects. This endpoint prioritizes quality over speed, making it ideal for advanced visuals that teach better and presentations.

Prism videos take longer to generate but offer superior visual quality with advanced animations and effects.

WebSocket Endpoint

wss://50fa8sjxo9.execute-api.us-west-2.amazonaws.com/production

Authentication

Include your API key in the WebSocket payload:

{
  "api_key": "YOUR_API_KEY"
}

Request Parameters

action · string · required

Must be set to "Pre-Rendered"

task · string · required

The content or topic for your video (e.g., “explain machine learning”)

api_key · string · required

Your Knowlify API key for authentication

quality · string · default: "high"

Video quality setting. Options: "low", "medium", "high", "production". Higher quality takes longer to generate.

Code Examples

Python

import asyncio
import websockets
import json

task = r'''
explain machine learning
'''

async def send_request(task):
    print("Sending request...")
    uri = "wss://50fa8sjxo9.execute-api.us-west-2.amazonaws.com/production"

    async with websockets.connect(uri) as websocket:
        payload = {
            "action": "Pre-Rendered",
            "task": task,
            "api_key": "YOUR_API_KEY"
        }
        await websocket.send(json.dumps(payload))

        while True:
            try:
                response = await websocket.recv()
                print("Received response:", response)
            except websockets.exceptions.ConnectionClosed:
                print("Connection closed by the server.")
                break

if __name__ == "__main__":
    asyncio.run(send_request(task))
