Suno AI API

Use API to call the music generation AI of Suno.ai and easily integrate it into agents like GPTs.

👉 We update quickly, please star.

Introduction

Suno is an amazing AI music service. Although the official API is not yet available, we couldn't wait to integrate its capabilities somewhere.

We discovered that some users have similar needs, so we decided to open-source this project, hoping you'll like it.

This implementation uses the paid 2Captcha service (a.k.a. ruCaptcha) to solve the hCaptcha challenges automatically and does not use any already made closed-source paid Suno API implementations.

Demo

We have deployed an example bound to a free Suno account, so it has daily usage limits, but you can see how it runs: suno.gcui.ai

Features

• Perfectly implements the creation API from suno.ai.
• Automatically keep the account active.
• Solve CAPTCHAs automatically using 2Captcha and Playwright with rebrowser-patches.
• Compatible with the format of OpenAI’s /v1/chat/completions API.
• Supports Custom Mode.
• One-click deployment to Vercel & Docker.
• In addition to the standard API, it also adapts to the API Schema of Agent platforms like GPTs and Coze, so you can use it as a tool/plugin/Action for LLMs and integrate it into any AI Agent.
• Permissive open-source license, allowing you to freely integrate and modify.

Getting Started

1. Obtain the cookie of your Suno account

1. Head over to suno.com/create using your browser.
2. Open up the browser console: hit F12 or access the Developer Tools.
3. Navigate to the Network tab.
4. Give the page a quick refresh.
5. Identify the latest request that includes the keyword ?__clerk_api_version.
6. Click on it and switch over to the Header tab.
7. Locate the Cookie section, hover your mouse over it, and copy the value of the Cookie.

2. Register on 2Captcha and top up your balance

2Captcha is a paid CAPTCHA solving service that uses real workers to solve the CAPTCHA and has high accuracy. It is needed because of Suno constantly requesting hCaptcha solving that currently isn't possible for free by any means.

Create a new 2Captcha account, top up your balance and get your API key.

[!NOTE] If you are located in Russia or Belarus, use the ruCaptcha interface instead of 2Captcha. It's the same service, but it supports payments from those countries.

[!TIP] If you want as few CAPTCHAs as possible, it is recommended to use a macOS system. macOS systems usually get fewer CAPTCHAs than Linux and Windows—this is due to its unpopularity in the web scraping industry. Running suno-api on Windows and Linux will work, but in some cases, you could get a pretty large number of CAPTCHAs.

3. Clone and deploy this project

You can choose your preferred deployment method:

Deploy to Vercel

Run locally

git clone https://github.com/gcui-art/suno-api.git
cd suno-api
npm install

Docker

[!IMPORTANT] GPU acceleration will be disabled in Docker. If you have a slow CPU, it is recommended to deploy locally.

Alternatively, you can use Docker Compose. However, follow the step below before running.

docker compose build && docker compose up

4. Configure suno-api

• If deployed to Vercel, please add the environment variables in the Vercel dashboard.

• If you’re running this locally, be sure to add the following to your .env file:

Environment variables

• SUNO_COOKIE — the Cookie header you obtained in the first step.
• TWOCAPTCHA_KEY — your 2Captcha API key from the second step.
• BROWSER — the name of the browser that is going to be used to solve the CAPTCHA. Only chromium and firefox supported.
• BROWSER_GHOST_CURSOR — use ghost-cursor-playwright to simulate smooth mouse movements. Please note that it doesn't seem to make any difference in the rate of CAPTCHAs, so you can set it to false. Retained for future testing.
• BROWSER_LOCALE — the language of the browser. Using either en or ru is recommended, since those have the most workers on 2Captcha. List of supported languages
• BROWSER_HEADLESS — run the browser without the window. You probably want to set this to true.

SUNO_COOKIE=<…>
TWOCAPTCHA_KEY=<…>
BROWSER=chromium
BROWSER_GHOST_CURSOR=false
BROWSER_LOCALE=en
BROWSER_HEADLESS=true

5. Run suno-api

• If you’ve deployed to Vercel:
• Please click on Deploy in the Vercel dashboard and wait for the deployment to be successful.
• Visit the https://<vercel-assigned-domain>/api/get_limit API for testing.
• If running locally:
• Run npm run dev.
• Visit the http://localhost:3000/api/get_limit API for testing.
• If the following result is returned:

{
  "credits_left": 50,
  "period": "day",
  "monthly_limit": 50,
  "monthly_usage": 50
}

it means the program is running normally.

6. Use Suno API

You can check out the detailed API documentation at : suno.gcui.ai/docs

API Reference

Suno API currently mainly implements the following APIs:

- `/api/generate`: Generate music
- `/v1/chat/completions`: Generate music - Call the generate API in a format that works with OpenAI’s API.
- `/api/custom_generate`: Generate music (Custom Mode, support setting lyrics, music style, title, etc.)
- `/api/generate_lyrics`: Generate lyrics based on prompt
- `/api/get`: Get music information based on the id. Use “,” to separate multiple ids.
    If no IDs are provided, all music will be returned.
- `/api/get_limit`: Get quota Info
- `/api/extend_audio`: Extend audio length
- `/api/generate_stems`: Make stem tracks (separate audio and music track)
- `/api/get_aligned_lyrics`: Get list of timestamps for each word in the lyrics
- `/api/clip`: Get clip information based on ID passed as query parameter `id`
- `/api/concat`: Generate the whole song from extensions

You can also specify the cookies in the Cookie header of your request, overriding the default cookies in the SUNO_COOKIE environment variable. This comes in handy when, for example, you want to use multiple free accounts at the same time.
