Sponge: Kling Elements Standard - List Tasks

Use this endpoint when you need to retrieve the status or history of previously submitted Kling Elements Standard image-to-video tasks via the Sponge/paysponge proxy. Prefer this over task-creation endpoints when your goal is monitoring or polling rather than submitting new jobs. Choose the sibling Kling 2.1 Standard list endpoint if you used the newer Kling 2.1 model instead.

• No tasks found — returns empty list if no tasks have been submitted
• Authentication or payment failure — x402 payment not accepted or insufficient funds
• Rate limiting — too many requests to the proxy endpoint
• Upstream Freepik API unavailability — proxy cannot reach the backend service
• Invalid query parameters — returns error if unsupported parameters are passed
