Music Use Cases

Cover workflow with persona and stems

This is the most common production-style flow when you want a stable voice identity and post-production assets.

Step 1: create a persona once

1. generate or locate a completed song whose voice you want to reuse
2. wait for the task to reach SUCCESS
3. call /suno/generate-persona with the completed taskId and audioId
4. store the returned personaId

Step 2: upload a song for cover generation

curl -X POST "https://gateway.api.anyint.ai/suno/upload-cover" \
  -H "Authorization: Bearer $ANYINT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "uploadUrl": "https://your-storage.com/original-song.mp3",
    "customMode": true,
    "instrumental": false,
    "model": "V5",
    "style": "R&B, soul, warm vocals",
    "title": "Cover Version",
    "personaId": "your-persona-id",
    "callBackUrl": "https://your-domain.com/callback"
  }'

Step 3: wait for completion and split stems

1. query /suno/query/task?taskId=... or wait for the callback
2. read the returned audioId
3. call /suno/vocal-removal
4. choose separate_vocal for two-track output or split_stem for multitrack output

New-song creation workflow

This flow works well for consumer apps, demo builders, and content studios.

Step 1: generate lyrics if needed

curl -X POST "https://gateway.api.anyint.ai/suno/generate-lyrics" \
  -H "Authorization: Bearer $ANYINT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A late-night R&B song about city life",
    "callBackUrl": "https://your-domain.com/callback"
  }'

Step 2: create the song

1. choose a lyric variant
2. call /suno/generate in custom mode
3. store the returned taskId
4. wait for the task to reach SUCCESS

Step 3: add post-processing

After the song is complete, you can optionally:

• call /suno/generate-cover for cover art
• call /suno/timestamped-lyrics for lyric alignment
• call /suno/wav-generate for lossless export
• call /suno/mp4-generate for music video output
