This documentation is valid for the following list of our models:

  • google/veo3

Overview

The model generates high-quality short videos from text or image prompts with significant advancements over its predecessor, Veo2.

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

Video Generation

You can generate a video using this API. In the basic setup, you only need a prompt.

post
Authorizations
Body
modelundefined · enumRequiredPossible values:
promptstringRequired

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

aspect_ratiostring · enumOptional

The aspect ratio of the generated video.

Possible values:
durationinteger · enumOptional

The length of the output video in seconds.

Possible values:
negative_promptstringOptional

The description of elements to avoid in the generated video.

enhance_promptbooleanOptional

Whether to enhance the video generation.

Default: true
seedintegerOptional

Varying the seed integer is a way to get different results for the same other request parameters. Using the same value for an identical request will produce similar results. If unspecified, a random number is chosen.

generate_audiobooleanOptional

Whether to generate audio for the video.

Default: true

Retrieve the generated video from the server

After sending a request for video generation, this task is added to the queue. Based on the service's load, the generation can be completed in a couple of minutes

or take a bit more.

Full Example: Generating and Retrieving the Video From the Server

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"
# Insert your AIML API Key instead of <YOUR_AIMLAPI_KEY>:
aimlapi_key = "<YOUR_AIMLAPI_KEY>"

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

    data = {
        "model": "google/veo3",
        "prompt": '''
A menacing evil dragon appears in a distance above the tallest mountain, then rushes toward the camera with its jaws open, revealing massive fangs. We see it's coming.
'''
    }
 
    response = requests.post(url, json=data, headers=headers)
    
    if response.status_code >= 400:
        print(f"Error: {response.status_code} - {response.text}")
    else:
        response_data = response.json()
        # print(response_data)
        return response_data
    

# Requesting the result of the task from the server using the generation_id
def get_video(gen_id):
    url = f"{base_url}/generate/video/google/generation"
    params = {
        "generation_id": gen_id,
    }
    
    headers = {
        "Authorization": f"Bearer {aimlapi_key}", 
        "Content-Type": "application/json"
        }

    response = requests.get(url, params=params, headers=headers)
    # print("Generation:", response.json())
    return response.json()

    gen_response = generate_video()
    gen_id = gen_response.get("id")

        timeout = 1000
        while time.time() - start_time < timeout:

            if response_data is None:
                print("Error: No response from API")
                break
        
            status = response_data.get("status")
            print("Status:", status)

            if status == "waiting" or status == "active" or  status == "queued" or status == "generating":
                print("Still waiting... Checking again in 10 seconds.")
                time.sleep(10)
            else:
                print("Processing complete:/n", response_data)
                return response_data
   
        print("Timeout reached. Stopping.")
        return None
