Suno Music Generation#

Generate songs via a local gcui-art/suno-api server.

Setup#

1. Clone and install: git clone https://github.com/gcui-art/suno-api && cd suno-api && npm install && npm run build
2. Create .env with your Suno cookie and optional 2Captcha key (see repo README)
3. Start server: PORT=3100 npm start (or create a LaunchAgent/systemd service)
4. Verify: curl http://localhost:3100/api/get_limit

Set SUNO_API_URL env var if not running on http://localhost:3100.

Quick Generate (simple mode)#

For casual requests ("make a song about X") — Suno writes the lyrics:

bash

scripts/suno.sh generate --prompt "DESCRIPTION" --wait

Custom Generate (full control)#

For specific lyrics and style:

bash

scripts/suno.sh custom --prompt "LYRICS" --style "GENRE TAGS" --title "TITLE" --wait

Add --instrumental for no vocals. Add --negative-tags "TAGS" to exclude styles.

Generate Lyrics First#

When user provides a theme but not lyrics — generate, review, then create:

bash

scripts/suno.sh lyrics --prompt "THEME"

Check Status / Credits#

bash

scripts/suno.sh status --ids "ID1,ID2"
scripts/suno.sh credits

Download Audio#

bash

scripts/suno.sh download --url "AUDIO_URL" --out "/path/to/file.mp3"

Workflow#

1. Vague idea → generate (Suno writes lyrics from description)
2. Specific vision → write lyrics, then custom with style tags and title
3. Review first → lyrics to generate, show user, edit, then custom
4. Always use --wait — blocks until audio URLs are ready (~60-120s)
5. Each generation creates 2 song variations
6. Download audio and send via message tool (as attachment)
7. Songs appear in the user's Suno library/playlists

Style Tags Examples#

• pop, upbeat, happy, female vocals
• country, acoustic guitar, male vocals, storytelling
• hip hop, trap beats, autotuned vocals
• classical, orchestral, cinematic
• rock, electric guitar, energetic, anthem
• thrash metal, aggressive riffs, double bass drums, distorted guitar
• jazz, smooth, saxophone, lounge
• lullaby, soft, gentle, music box
• folk, banjo, americana, warm
• edm, electronic, dance, synth
• r&b, soulful, smooth, groovy

Cookie Refresh#

If auth errors occur, refresh the Suno cookie:

1. Open suno.com/create in browser → DevTools (F12) → Network tab
2. Refresh page → find request with ?__clerk_api_version
3. Copy the Cookie header value → update .env → restart server

Notes#

• Default model: Suno v5 ( chirp-crow); override via --model flag
• Each generation uses credits (~10 per song pair)
• Audio files are MP3, typically 2-4 min
• 2Captcha key optional but recommended for long-term stability
