Inputs
- Upload URL (required) — The publicly accessible URL of the audio file to upload and extend.
- Prompt — Optional text description to guide the audio extension generation.
- Reply URL — Webhook URL that will be called when the extend task completes.
- Reply Ref — Custom reference string included in the webhook callback for identification.
- Wait for Completion — Boolean flag to determine if execution should wait for the task to complete; polls status every 3 seconds with a 5-minute timeout.
Output shape
a JSON array of one or more objects representing the API response data from the upload and extend request
If 'Wait for Completion' is enabled, the operation polls the task status endpoint until the task finishes, returning the final result. Otherwise, it returns the immediate response which may include a task ID for later querying.
