  • Auto-refresh tokens when they expire

Requirements

  • Node.js 18+

  • BrowserOS running on port 9000 with an active Suno session

  • A Suno account (free or paid)

How It Works

Authentication

Suno uses Clerk for auth with short-lived JWT tokens (~1 hour). The client:

  1. Checks the __session cookie from BrowserOS via Chrome DevTools Protocol (CDP)

  2. If expired, reloads the Suno page to trigger a token refresh

  3. Captures the fresh token from network requests

Song Generation

Direct API calls fail due to hCaptcha. Instead, we:

  1. Connect to the Suno page via CDP

  2. Inject JavaScript to fill the form (lyrics, style)

  3. Click the Create button (CAPTCHA runs invisibly in browser context)

  4. Capture song IDs from the network response

Example

// Generate a song const result = await suno_generate_song({ lyrics: "[Verse]\nHello world\n\n[Chorus]\nThis is a test", style: "indie folk, acoustic, male vocals" }); // Wait for it to complete const songs = await suno_wait_for_songs({ ids: result.songIds }); // Download it await suno_download_song({ songId: songs[0].id, folder: "./downloads" });

Known Limitations

  • Title field doesn't work reliably (Suno UI limitation)

  • Requires BrowserOS with an active Suno session

  • Token expires every ~1 hour (auto-refreshes)
