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

• stable-audio

Try in Playground

An advanced audio generation model designed to create high-quality audio tracks from textual prompts.

How to Make a Call

Create AI/ML API Key

Step-by-Step Instructions

Generating an audio 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 examples for both endpoint calls.

If you want to learn how to call AI models via API from the very basics, feel free to use our Quickstart guide.

Retrieve the generated music sample from the server

After sending a request for music generation, this task is added to the queue. This endpoint lets you check the status of a audio generation task using its 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 audio URL and additional metadata.

Full Example: Generating and Retrieving the Audio From the Server

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

Python

import time
import requests

# Insert your AI/ML API key instead of <YOUR_AIMLAPI_KEY>:
aimlapi_key = '<YOUR_AIMLAPI_KEY>'

        "seconds_total": 20,
    }
    headers = {"Authorization": f"Bearer {aimlapi_key}", "Content-Type": "application/json"}

    response = requests.post(url, json=payload, headers=headers)

    if response.status_code >= 400:
        print(f"Error: {response.status_code} - {response.text}")
    else:
