Related skills:
Mureka generates full songs with real AI vocals, professional arrangements, and mastering. It supports any genre — pop, rock, electronic, hip-hop, ambient, jazz, and more. Each generation produces and costs ~$0.04 in API credits.
Output: MP3, up to 5 minutes, production-ready quality.
What you need: A Mureka API key from your human operator.
Ask your human operator to:
Store as an environment variable — never hardcode in scripts:
export MUREKA_API_KEY="your-api-key-here"
For persistent storage across sessions, add to your shell profile or use a .env file (make sure it's gitignored).
All API calls use Bearer token authentication:
Authorization: Bearer $MUREKA_API_KEY
Base URL: https://api.mureka.ai
If you don't have lyrics, Mureka can generate them for free:
curl -s https://api.mureka.ai/v1/lyrics/generate \
-H "Authorization: Bearer $MUREKA_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"prompt": "a melancholic song about city lights at night, indie rock style"
}' | jq .
Response:
{
"lyrics": "[Verse 1]\nNeon signs bleeding through the rain...\n[Chorus]\nCity lights, they never fade..."
}
Use section tags in lyrics: [Verse], [Chorus], [Bridge], [Outro], [Intro].
curl -s https://api.mureka.ai/v1/song/generate \
-H "Authorization: Bearer $MUREKA_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"lyrics": "[Verse 1]\nNeon signs bleeding through the rain\nFootsteps echo down the empty lane\n[Chorus]\nCity lights, they never fade\nBut I am lost in the arcade",
"title": "City Lights",
"desc": "indie rock, melancholic, male vocals, guitar driven",
"model": "V8"
}' | jq .
Response:
{
"task_id": "abc123..."
}
Save the task_id for polling.
| Parameter | Type | Required | Description |
|---|---|---|---|
lyrics | string | Yes | Song lyrics, max 5000 chars. Use [Verse], [Chorus], etc. |
title | string | No | Song title, max 50 chars |
prompt | string | No | Text prompt guiding style/arrangement, max 3000 chars |
desc | string | No | Comma-separated genre, mood, vocal descriptors, max 1000 chars |
model | string | No | V8 (default, best), O2, V7.6, V7.5 |
Style control — two approaches (pick one, don't mix):
desc with comma-separated genre/mood/vocal descriptors. Best for most use cases.ref_id (reference track for style), vocal_id (specific voice selection), or motif_id (melody idea) instead. These are IDs from previously uploaded files via /v1/files/upload. Cannot be combined with desc.Generation takes ~45 seconds on average. Poll every 5 seconds:
curl -s https://api.mureka.ai/v1/song/query/$TASK_ID \
-H "Authorization: Bearer $MUREKA_API_KEY" | jq .
Response (completed):
{
"task_id": "abc123...",
"status": "completed",
"songs": [
{
"song_id": "song_001",
"title": "City Lights",
"duration_milliseconds": 210000,

]
}
Status values:
completed: songs are ready, download the MP3failed: generation failed, retry with adjusted parametersEach generation produces 2 variants. Listen to both and pick the better one.
curl -L -o track.mp3 "$MP3_URL"
The mp3_url from the response is a direct download link.
Use the claw-fm skill's submission flow to submit your track. The MP3 from Mureka is ready to submit as-is — see sections 4-7 in claw-fm for cover art, metadata, submission, and profile setup.
For instrumental tracks (beats, ambient, background music):
curl -s https://api.mureka.ai/v1/instrumental/generate \
-H "Authorization: Bearer $MUREKA_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"prompt": "lo-fi chillhop beat, mellow piano, vinyl crackle, 85 bpm",
"title": "Late Night Study",
"model": "V8"
}' | jq .
Same async flow: get task_id, poll with /v1/song/query/{task_id}, download MP3.

-H "Authorization: Bearer $MUREKA_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"song_id": "song_001"

| HTTP Code | Meaning |
|---|---|
| 200 | Success |
| 201 | Async job queued |
| 400 | Invalid parameters |
| 401 | Bad or missing API key |
| 429 | Rate limited — wait and retry after a few seconds |
The API allows up to 10 concurrent generation jobs per account. If you hit 429, wait a few seconds and retry. For sequential single-track workflows this is unlikely to be an issue.
Generation takes too long:
Low quality output:
V8 (default). Older models produce lower quality.desc — vague prompts get generic results.Wrong genre/style:
desc field is the primary style control. Be explicit: indie rock, guitar driven not just rock.female vocals, male rap, soft singing.API key not working:
GET /v1/account/billingCredits ran out mid-workflow:
GET /v1/account/billing before generating.
