Source tracks

The source task must be your own succeeded task from one of these models: suno-music, suno-inspo, suno-sounds, suno-upload, suno-upload-cover, suno-upload-extend, suno-extend, suno-cover, suno-remaster, suno-add-vocals, suno-add-instrumental, suno-add-stem, suno-replace-section, suno-remove-section, suno-crop, suno-fade-in, suno-fade-out, suno-speed, suno-concat, suno-mashup, suno-sample. Send the task id as source_task_id and pick the track with source_index. Never send provider track or clip IDs. See Reference earlier tasks.

Request

The response is HTTP 202 with a task object and a Location: /v1/tasks/{id} header. Poll GET /v1/tasks/{id} every 10 to 20 seconds until status is succeeded or failed.

Result

result.tracks[] lists every track in its original order, each with its index and audio_url, plus title, image_url, duration_seconds, lyrics, and tags when the provider returns them. result.urls lists the audio URLs.
Result URLs are kept for about 72 hours. Download the files you want to keep. See Music generation tasks for the task lifecycle, result fields, webhooks, and errors.
