SUNO allows us to set the singer style for songs that have already been generated, and then create secondary works based on it. This document explains the integration method for the relevant API. This API has only three input parameters: first, audio_id, which is the ID of a song that has been successfully generated by the official service; second, name and description, which are a name and description of the singer style. Here, the audio_id we input is https://cdn.acedata.cloud/2qhzs3.png, which can refer to the Suno Audios Generation API for custom song generation, and finally obtain the audio_id. 
curl -X POST 'https://api.acedata.cloud/suno/persona' \
-H 'accept: application/json' \
-H 'authorization: Bearer {token}' \
-H 'content-type: application/json' \
-d '{
  "name": "test",
  "audio_id": "81745564-60e7-4ad4-85a9-6f42f0f4f3b3",
  "description": "test"
}'
The result is as follows: 
{
  "success": true,
  "task_id": "8e808558-f056-456f-91d6-b97fd94eb3be",
  "data": {
    "persona_id": "dae4ae5d-2b51-4af1-b286-1a4473ef4dba"
  }
}
As can be seen, the persona_id field in data is the ID of the generated singer style. With the singer style ID, we can use the Suno Audios Generation API to generate custom songs. For example, pass action as artist_consistency, while audio_id is the uploaded song ID, and also upload the parameter persona_id, which is the singer style ID returned above, to generate new songs based on the reference singer style.
