# Create Music

> Creates a music generation task using Suno

<Note>
  For coding agents, discover the current recommended music shortlist first with `GET /v1/models?recommended_for=music`, then send the selected `model` explicitly to this endpoint.
</Note>

Generate music and lyrics using AI. This is an asynchronous API. Create responses return a task identity, and may also return a preferred `poll_url` for status checks.

## Request Body

<ParamField body="model" type="string" default="suno_music">
  Model to use: `suno_music` for music generation, `suno_lyrics` for lyrics only.
</ParamField>

<ParamField body="prompt" type="string">
  Music description. Required for music, lyrics, upload-cover, and upload-extend requests; omit for add-instrumental.
</ParamField>

<ParamField body="title" type="string">
  Title for the generated song.
</ParamField>

<ParamField body="tags" type="string">
  Style tags (e.g., "pop, upbeat, electronic").
</ParamField>

<ParamField body="negative_tags" type="string">
  Styles to avoid. Required when `audio_operation` is `add-instrumental`.
</ParamField>

<ParamField body="action" type="string">
  Generation type: `MUSIC` (default) or `LYRICS`.
</ParamField>

<ParamField body="mv" type="string">
  Official Suno model version. Required for music generation (when `action` is omitted or `MUSIC`); omit for lyrics-only requests. Supported values: `chirp-v3-5`, `chirp-v4`, `chirp-v4-5`, `chirp-v4.5`, `chirp-v4-5plus`, `chirp-v4.5plus`, `chirp-v4-5all`, `chirp-v4.5all`, `chirp-v5`, `chirp-v5-5`, `chirp-v5.5`.
</ParamField>

<ParamField body="make_instrumental" type="boolean">
  Set to `true` to generate instrumental output without vocals.
</ParamField>

<ParamField body="audio_url" type="string">
  Publicly reachable reference or uploaded audio URL. When provided without `audio_operation`, TokenLab uses the upload-cover flow.
</ParamField>

<ParamField body="audio_operation" type="string">
  Uploaded-audio mode: `upload-cover`, `upload-extend`, or `add-instrumental`. `upload-extend` requires `continue_at`; `add-instrumental` requires `audio_url`, `title`, `tags`, and `negative_tags`.
</ParamField>

<ParamField body="continue_clip_id" type="string">
  ID of a previous clip to continue from.
</ParamField>

<ParamField body="continue_at" type="number">
  Timestamp (in seconds) to continue from. Required when `audio_operation` is `upload-extend`.
</ParamField>

## Response

<ResponseField name="id" type="string">
  Task ID for polling status.
</ResponseField>

<ResponseField name="task_id" type="string">
  Async task identifier alias when returned by the adapter.
</ResponseField>

<ResponseField name="poll_url" type="string">
  Preferred polling URL for this task when provided.
</ResponseField>

<ResponseField name="status" type="string">
  Task status: `pending`, `processing`, `completed`, or `failed`.
</ResponseField>

<ResponseField name="created" type="integer">
  Unix timestamp of task creation.
