Sponge: Kling Elements Pro – List Tasks

Use this endpoint when you need to poll or monitor the status of previously submitted Kling Elements Pro image-to-video generation jobs, especially in workflows that submit tasks asynchronously and need to check for completion before retrieving results. Prefer this over submit endpoints when you already have tasks in flight and want a full task list rather than a single task status.

• No tasks found — returns empty list if no tasks have been submitted
• Authentication or payment header missing — returns 402 or 401 error
• Gateway timeout if the upstream Freepik/Kling API is unavailable
• Rate limiting if too many requests are made in a short window
• Malformed response if the upstream Kling Elements Pro API changes its schema
