What Is the Suno AI Music Generation API?

The Suno AI Music Generation API is a RESTful interface that allows developers to generate original songs—both instrumentals and vocals—by sending structured JSON requests. Whether you're building a music app, a virtual artist experience, or dynamic background music for a game, Suno provides you with the tools to create royalty-free, high-quality tracks in real time.


Key Features

Capability Description
Music Generation Turn prompts like “sad acoustic ballad with male vocals” into full tracks.
Lyrics Generation Auto-generate song lyrics, suggested titles, and even line-by-line timestamps.
Custom Mode Set your own title, genre, mood, or insert custom lyrics for personalized compositions.
Audio Processing Convert tracks to WAV, remove vocals (karaoke), extend compositions, or replace sections.
Music Video Creation Generate synchronized MP4 videos with visuals—ideal for social sharing or branding.
Streaming Output Fast generation, watermark-free, with support for high concurrency.
Advanced Editing Extend or regenerate tracks, split stems, and remix without starting from scratch.

  • Flexible Licensing: Suitable for ads, games, YouTube videos, apps, and more.

Important: Always review the licensing terms per plan—most premium tiers grant full rights to use the content in commercial products without attribution or royalties.


How It Works (Simplified Example)

json
POST /api/v1/generate { "prompt": "An emotional piano ballad with soft female vocals", "instrumental": false, "customMode": true, "title": "Shattered Stars", "lyrics": "Falling fast, into the dark...", "genre": "Pop" }

In return, you’ll receive URLs to download the MP3/WAV/MP4 files and status tracking.

6. Pricing & Access

Tier Typical Limits Best For
Free 10–20 tracks/day, MP3 only Hackathons, prototypes
Developer Higher rate limit, WAV access Indie apps, small studios
Commercial Priority queue, video, unlimited seats SaaS platforms, large agencies

Always check rate‑limit headers and monitor credit usage to avoid throttling.


7. Best‑Practice Checklist

  1. Secure Your Keys – Store them in env variables, not source control.

  2. Handle Webhooks – Faster than polling; scale without hitting rate caps.

  3. Cache Results – Audio links often expire after ~15 days. Archive if needed.

  4. Batch Wisely – Queue generation during off‑peak hours if you have large jobs.

  5. Legal Review – Verify that your provider’s license grants the rights you need (commercial, distribution, derivative works).


8. Choosing a Provider

Evaluate each option on:

Factor What to Ask
Speed How fast is first audio byte?
Quality Controls Can I specify BPM, key, or vocal gender?
Cost CPM of generated minutes; overage fees?
Support Slack/Discord channels, ticket SLAs, sample code?
Compliance GDPR, SOC2, watermark‑free, explicit rights?
