Suno Music - AI Music Generation

Generate music using Suno AI's API.

Setup (One-Time)

•Sign in to suno.ai
•Open browser DevTools (F12) → Console tab
•Run: document.cookie
•Find the __session=eyJ... part (it's a long JWT token)
•Export it: export SUNO_COOKIE="__session=eyJ..."

Note: The __session token expires after ~1 hour. You'll need to refresh it periodically.

Usage

Run the generation script:

bash

python3 ~/.claude/skills/suno-music/generate_music.py "your prompt here" [options]

Options

Option	Description	Default
`--custom`	Treat prompt as lyrics (not description)	False
`--tags`	Style/voice tags (e.g., "female voice, pop, upbeat")	None
`--title`	Song title	None
`--instrumental`	Generate instrumental only (no vocals)	False
`--output`	Output directory path	./generated_music
`--model`	Model key (e.g., chirp-auk-turbo)	Default free model

Examples

Generate from description

bash

python3 ~/.claude/skills/suno-music/generate_music.py "an upbeat electronic track for a tech product demo"

Custom lyrics with style

bash

python3 ~/.claude/skills/suno-music/generate_music.py "[Verse 1]
Walking through the morning light
Everything feels just right" --custom --tags "indie folk, acoustic guitar, male voice" --title "Morning Light"

Instrumental track

bash

python3 ~/.claude/skills/suno-music/generate_music.py "epic orchestral trailer music with building tension" --instrumental

Output

Songs are saved with format: {timestamp}_{sanitized_title}_{n}.mp3

Example: 20260106_morning_light_1.mp3

Suno generates 2 variations per request by default.

Credits

•Free tier: 50 credits/day (renews daily)
•Each generation uses 10 credits (5 per song × 2 variations)
•So you can generate 5 songs per day on the free tier

Check remaining credits:

bash

python3 ~/.claude/skills/suno-music/generate_music.py --credits

Models

Model	Key	Notes
v4.5-all	chirp-auk-turbo	Best free model (default)
v5	chirp-crow	Pro only, beta
v4.5+	chirp-bluejay	Pro only
v4	chirp-v4	Pro only

Requirements

•Python 3.x
•requests library (usually pre-installed)
•SUNO_COOKIE environment variable with __session token

Troubleshooting

"API Error: 401" - Token expired. Get a fresh __session token from the browser.

"API Error: 402" - Out of credits. Wait for daily refresh or upgrade.
