Producer Music Generation

Generate AI music through AceDataCloud's Producer API.

Setup: See authentication for token setup.

  -H "Content-Type: application/json" \
  -d '{"action": "generate", "prompt": "upbeat electronic dance track with synth leads"}'

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

Gotchas

• Use [Verse], [Chorus], [Bridge], [Outro] tags in custom lyrics
• continue_at is in seconds — the song extends from that point
• replace_section_start / replace_section_end define the time range to regenerate
• weirdness at 0 = predictable, at 1 = highly experimental
• Upload a reference audio via /producer/upload to get an audio ID for use with cover or extend
• WAV and video downloads are separate endpoints — call them after the main generation completes
• CRITICAL: Check the state field in task responses — 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
