Sponge: Kling 2.1 Pro Image-to-Video – List Tasks

Use this endpoint when you need to enumerate or poll all Kling 2.1 Pro image-to-video tasks previously submitted through the Sponge proxy, especially to check job completion status before downloading results. Prefer this over task-specific status endpoints when you need a full overview of all jobs.

• No tasks found — returns empty list if no jobs have been submitted
• Authentication/payment failure — x402 payment not accepted or invalid
• Gateway error — paysponge.com proxy unreachable or returns 5xx
• Rate limiting — too many requests to the Kling endpoint
