Suno Music Generation

Generate AI-powered music through AceDataCloud's Suno API.

Setup: See authentication for token setup.

Quick Start

curl -X POST https://api.acedata.cloud/suno/audios \
  -H "Authorization: Bearer $ACEDATACLOUD_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "a happy pop song about coding", "model": "chirp-v5-5", "callback_url": "https://api.acedata.cloud/health"}'

Async: All generation is async. See async task polling. Poll via POST /suno/tasks with {"task_id": "..."} every 3-5 seconds.

Available Models

Model	Best For
chirp-v5-5	Latest, highest quality
chirp-v5	High quality
chirp-v4-5-plus	Enhanced v4.5
chirp-v4-5	Good balance of quality and speed
chirp-v4	Fast, reliable
chirp-v3-5	Legacy, stable
chirp-v3-0	Legacy

Core Workflows

1. Quick Generation (Inspiration Mode)

Generate a song from a text description. Suno creates lyrics, style, and music automatically.

POST /suno/audios
{
  "prompt": "an upbeat electronic track about the future of AI",
  "model": "chirp-v5-5",
  "instrumental": false
}

2. Custom Generation (Full Control)

Provide your own lyrics, title, and style for precise control.

POST /suno/audios
{
  "custom": true,
  "lyric": "[Verse]\nCode is poetry in motion\n[Chorus]\nWe build the future tonight",
  "title": "Digital Dreams",
  "style": "Synthwave, Electronic, Dreamy",
  "model": "chirp-v5-5",
  "vocal_gender": "f"
}

3. Extend a Song

Continue an existing song from a specific timestamp with new lyrics.

POST /suno/audios
{
  "action": "extend",
  "audio_id": "existing-audio-id",
  "lyric": "[Bridge]\nNew section lyrics here",
  "continue_at": 120.0,
  "style": "Same style as original"
}

4. Cover / Remix

Create a new version of an existing song in a different style.

POST /suno/audios
{
  "action": "cover",
  "audio_id": "existing-audio-id",
  "style": "Jazz, Acoustic, Mellow"
}

5. Full Song Creation Workflow

For best results follow this multi-step workflow:

1. Generate lyrics — POST /suno/lyrics with a topic/prompt
2. Optimize style — POST /suno/style to refine style description
3. Generate music — POST /suno/audios with custom action, lyrics + style
4. Poll task — POST /suno/tasks with task_id until status is complete
5. Optional: Extend — Use extend action to add more sections
6. Optional: Concat — Use concat action to merge extended segments
7. Optional: Convert — Get WAV (/suno/wav), MIDI (/suno/midi), or MP4 (/suno/mp4)

Gotchas

• All generation is async — always set "callback_url" to get a task_id immediately, then poll /suno/tasks
• CRITICAL: Check the state field — only state: "complete" with success: true means done. During pending, the API may return intermediate audio_url values (streaming previews). Do NOT stop polling just because audio_url is non-empty
• Lyrics max ~3000 characters. For longer songs, use the extend workflow
• Style tags are descriptive phrases, not enum values (e.g., "Synthwave, Electronic, Dreamy")
• vocal_gender ("f"/"m") is only supported on v4.5+ models
• variation_category ("high"/"normal"/"subtle") is only supported on v5+ models
• The concat action merges extended song segments — requires audio_id of the extended track
• persona requires an existing audio_id to extract the vocal reference from
• Upload external audio via /suno/upload before using it with extend/cover
