Sponge: Kling O1 Image-to-Video – List Tasks

Use this endpoint when you need to poll or monitor the status of previously submitted Kling O1 image-to-video jobs through the Sponge/paysponge.com x402 proxy. Prefer this over other list-tasks endpoints when you specifically submitted jobs to the Kling O1 model (as opposed to Kling 2.1, MiniMax, Seedance, or other models available on the same platform).

• No tasks found — returns empty list if no jobs have been submitted
• Authentication or payment failure — x402 payment not processed correctly, returns 402 or 401 error
• Rate limiting — too many requests in a short window, returns 429
• Upstream Freepik API unavailable — proxy returns 502 or 503
• Invalid query parameters — returns 400 if unsupported params are passed
