Complete Workflow

This guide walks through the full flow of generating music with sunor: authenticate, create a task, poll until it completes, and use the audio output.

​
Prerequisites

  • A sunor account with an API key
  • Credits in your account (music costs 10 credits)

​
Step 1: Create a task

Submit a music generation request:
The example below uses Suno’s input shape (gpt_description_prompt, make_instrumental). Udio uses a different shape (prompt, lyrics_type) — see /models/udio before adapting this snippet to "model": "udio".
import requests

API_KEY = "YOUR_API_KEY"
BASE_URL = "https://sunor.cc/api/v1"

response = requests.post(
    f"{BASE_URL}/task",
    headers={
        "Content-Type": "application/json",
        "x-api-key": API_KEY,
    },
    json={
        "model": "suno",
        "task_type": "music",
        "input": {
            "gpt_description_prompt": "A chill lo-fi beat for studying, soft piano and vinyl crackle",
            "make_instrumental": True,
        },
    },
)

task = response.json()["data"]
task_id = task["task_id"]
print(f"Task created: {task_id} (status: {task['status']})")
The response returns a task_id with status "pending". Credits are frozen immediately.

​
Step 2: Poll for results

Tasks take 30 seconds to 5 minutes to complete. Poll every 5-10 seconds until the status is terminal (success, failure, or timeout). 
import time

def wait_for_task(api_key, task_id, interval=5):
    """Poll until the task completes. Returns the task data."""
    while True:
        response = requests.get(
            f"{BASE_URL}/task/{task_id}",
            headers={"x-api-key": api_key},
        )
        data = response.json()["data"]
        status = data["status"]
        print(f"  Status: {status}")

        if status in ("success", "failure", "timeout"):
            return data

        time.sleep(interval)

result = wait_for_task(API_KEY, task_id)

​
Step 3: Use the output

On success, the output.result contains an array of generated clips: 
if result["status"] == "success":
    clips = result["output"]["result"]
    for clip in clips:
        print(f"Title: {clip['title']}")
        print(f"Audio: {clip['audio_url']}")
        print(f"Cover: {clip['image_url']}")
        print()
else:
    print(f"Task failed: {result['error']}")

​
Downloading the audio

Audio URLs point to MP3 files hosted on Suno’s CDN. You can download them directly: 
import urllib.request

clip = clips[0]
filename = f"{clip['title']}.mp3"
urllib.request.urlretrieve(clip["audio_url"], filename)
print(f"Downloaded: {filename}")

​
Full example

Putting it all together: 
import requests
import time

API_KEY = "YOUR_API_KEY"
BASE_URL = "https://sunor.cc/api/v1"

# 1. Create task
print("Creating music task...")
response = requests.post(
    f"{BASE_URL}/task",
    headers={
        "Content-Type": "application/json",
        "x-api-key": API_KEY,
    },
    json={
        "model": "suno",
        "task_type": "music",
        "input": {
            "gpt_description_prompt": "A chill lo-fi beat for studying",
            "make_instrumental": True,
        },
    },
)
task_id = response.json()["data"]["task_id"]
print(f"Task ID: {task_id}")

# 2. Poll for results
print("Waiting for completion...")
while True:
    response = requests.get(
        f"{BASE_URL}/task/{task_id}",
        headers={"x-api-key": API_KEY},
    )
    data = response.json()["data"]

    if data["status"] in ("success", "failure", "timeout"):
        break
    time.sleep(5)

# 3. Use the output
if data["status"] == "success":
    for clip in data["output"]["result"]:
        print(f"  {clip['title']}: {clip['audio_url']}")
else:
    print(f"Failed: {data['error']}")
