How to Make a Call

Step-by-Step Instructions

Generating a video using this model involves sequentially calling two endpoints:

  • The first one is for creating and sending a video generation task to the server (returns a generation ID).

  • The second one is for requesting the generated video from the server using the generation ID received from the first endpoint.

Below, you can find two corresponding API schemas and an example with both endpoint calls.

API Schemas

Create a video generation task and send it to the server

post
Authorizations
Body
modelundefined · enumRequiredPossible values:
image_urlstring · uriRequired
promptstringRequired

The text description of the scene, subject, or action to generate in the video.

durationinteger · enumOptional

The length of the output video in seconds.

Possible values:
negative_promptstringOptional

The description of elements to avoid in the generated video.

cfg_scalenumber · max: 1Optional

The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt.

Retrieve the generated video from the server

After sending a request for video generation, this task is added to the queue. This endpoint lets you check the status of a video generation task using its generation_id, obtained from the endpoint described above. If the video generation task status is complete, the response will include the final result — with the generated video URL and additional metadata.

Code Example (Python)

The code below creates a video generation task, then automatically polls the server every 10 seconds until it finally receives the video URL.

import requests
import time

base_url = "https://api.aimlapi.com/v2"
api_key = "<YOUR_AIMLAPI_KEY>"

# Creating and sending a video generation task to the server
def generate_video():
    url = f"{base_url}/generate/video/kling/generation"
    headers = {
        "Authorization": f"Bearer {api_key}", 
    }

    data = {
        "model": "klingai/v2.1-master-image-to-video",

    }
 
    response = requests.post(url, json=data, headers=headers)
    
    if response.status_code >= 400:
        print(f"Error: {response.status_code} - {response.text}")
    else:
