How to Use Suno API with Python: Step-by-Step Tutorial
Meta Description: A practical Python tutorial on using the Suno API for music generation. Learn how to submit async tasks, poll for results, and implement custom lyrics in your own application.
TL;DR
- Goal: Generate AI music tracks (vocals + instrumentals) using Python.
- Pattern: Asynchronous task API (Submit → Poll → Get Result).
- Prerequisites: EvoLink API Key, Python 3.x,
requestslibrary. - Key Models:
suno-v5-beta,suno-v4.5-beta. - Tutorial: Jump directly to Step 1.
Step 1: Installation
You need the
requests library for HTTP communication.pip install requestsStep 2: The Core Workflow (Async Pattern)
Unlike standard text models, Suno music generation takes 20-45 seconds. We use an Asynchronous Task Pattern:
- Submit Task: POST request to
/v1/audios/generations. - Get Task ID: API returns an
idimmediately. - Poll Status: GET request to
/v1/tasks/{task_id}until status iscompleted. - Download Result: Retrieve the generated audio URL from
result_data[0].audio_url.

Step 3: Python Implementation
1. Initialize Client
import requests
import time
API_KEY = "sk-your-evolink-key"
BASE_URL = "https://api.evolink.ai/v1"
headers = {
"Authorization": f"Bearer {API_KEY}",
"Content-Type": "application/json"
}2. Submit Generation Task
def submit_suno_task(prompt, model="suno-v5-beta"):
url = f"{BASE_URL}/audios/generations"
payload = {
"model": model,
"prompt": prompt
}
response = requests.post(url, headers=headers, json=payload)
response.raise_for_status()
# Returns the 'id' field
return response.json()["id"]
task_id = submit_suno_task("Upbeat pop song for Instagram Reels, energetic vocals")
print(f"Task submitted: {task_id}")3. Poll for Results
def get_song_result(task_id):
url = f"{BASE_URL}/tasks/{task_id}"
while True:
response = requests.get(url, headers=headers)
data = response.json()
status = data["status"]
if status == "completed":
# Access result from result_data list
return data["result_data"][0]["audio_url"]
elif status == "failed":
raise Exception(f"Task failed: {data.get('error')}")
print("Still generating...")
time.sleep(5) # Poll every 5 seconds
song_url = get_song_result(task_id)
print(f"Song ready: {song_url}")Step 4: Advanced Features
Using Custom Lyrics
Structure your lyrics using standard tags for better control over song structure.
lyrics_prompt = """
[Verse 1]
Walking down the street, feeling the beat
City lights are shining, life is so sweet
[Chorus]
We're alive tonight, dancing in the moonlight
Everything's alright, we're shining so bright
"""
task_id = submit_suno_task(lyrics_prompt)Applying Personas
Use the
persona_id parameter to maintain consistent vocal style across generations (requires v4+). Set custom_mode=True to enable custom structure.payload = {
"model": "suno-v5-beta",
"prompt": "Pop song",
"persona_id": "your-persona-id",
"custom_mode": True
}Troubleshooting & FAQ
Q: Why do I get a "Task failed" error?
A: Ensure your prompt length and style parameters follow current documentation standards. Ensure your account has sufficient credits.

Q: How do I handle timeouts?
A: Never use synchronous blocking code. Always implement a polling loop or use a webhook callback (recommended for high-volume apps).

Q: Can I change the model?
A: Yes, use
A: Yes, use
suno-v4.5-beta for faster/cheaper generations or suno-v5-beta for studio-quality audio.Start Generating
