}Operations are enabled individually by server configuration. Disabled operations return 503 without a task. Music credit deduction is currently disabled.
Using this operation
Register an existing audio URL to obtain an APIstable audio ID for covering or extending it.-
- Prepare the fields shown in the example below. Replace sample URLs and IDs with resources you can access.
-
- Set model to suno_upload and place the parameters inside input. Submit once and save the returned task_id.
-
- Query the saved task or receive its callback. A processing result is not a reason to submit the operation again.
- Read songs from result.data.data. Each song has its own APIstable id, which can be used as audio_id in a later task.
Create task
Send model and input to the common task endpoint. callback_url is an optional top-level public HTTPS address. All resource IDs are APIstable IDs owned by your account. Music credit deduction is currently disabled.{
"model": "suno_upload",
"input": {
"upload_url": "https://example.com/sample.mp3"
}
}
Acceptance response
HTTP 200 confirms acceptance, not completion. Query GET /api/v1/tasks/{task_id} until data.status is succeeded or failed. Read data.result only after success; a failed task has its error in data.message.{
"code": 200,
"msg": "success",
"data": {
"task_id": "YOUR_TASK_ID"
}
}
Parameter reference
| Field | Type | Required | Description and limits |
|---|---|---|---|
| upload_url | string | Yes | Public HTTPS audio URL on port 443, without URL credentials. Use MP3/WAV/FLAC/OGG/M4A/AAC with a readable audio track. See the operation size limit. |
| copyright_audio | boolean | No / conditional | PayAPI upload extension, default false; enabling may incur additional supplier cost. default: false |
Inputs and limits
The schema lists supported fields, types and basic limits. Also follow Important conditions: cross-field and source-resource checks are not fully represented in JSON Schema. Unknown parameters are rejected. URL fields accept public HTTPS URLs, never file objects.{
"$schema": "https://json-schema.org/draft/2020-12/schema",
"type": "object",
"properties": {
"upload_url": {
"type": "string",
"format": "uri",
"description": "Public HTTPS audio URL on port 443, without URL credentials. Use MP3/WAV/FLAC/OGG/M4A/AAC with a readable audio track. See the operation size limit."
},
"copyright_audio": {
"default": false,
"type": "boolean",
"description": "PayAPI upload extension, default false; enabling may incur additional supplier cost."
}
},
"required": [
"upload_url"
],
"additionalProperties": false
}
Important conditions
- Audio URL inputs must contain readable MP3/WAV/FLAC/OGG/M4A/AAC audio with positive duration; the limit is 500 MiB per file. URLs must be publicly accessible HTTPS on port 443, without embedded credentials or private-network addresses. Keep them accessible until the task finishes.
- Song audio may be MP3 or M4A. Use suno_export_mp3 for an actual MP3 file. Unavailable optional cover art may be null; audio remains usable.
- Uploaded files last 24 hours, generated files 14 days and task details 30 days. Reused files keep their original expiry. Valid Voice/Persona identity mappings are separate from task-log cleanup. Download files you need to retain.
Result schema
The creation response is {code:200,msg:“success”,data:{task_id}}. Poll GET /api/v1/tasks/{task_id}. On success, data.result is an object matching the schema below; it is otherwise null. input remains a JSON string.{

Song duration is in seconds; task duration is in milliseconds. createTime is a Unix timestamp in milliseconds or null. Current stream_audio_url and source_stream_audio_url are null. source_audio_url/source_image_url refer to the same APIstable-hosted copies as audio_url/image_url, not provider links. Process the actual song array; upload registration does not imply two newly generated songs.
