Lists existing image-to-video generation tasks for the Kling 2.1 Standard model via the Sponge x402 payment proxy

## Facts

- Endpoint: GET https://freepik.x402.paysponge.com/v1/ai/image-to-video/kling-v2-1-std
- Price: Free
- Status: down
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/freepik-4c3f71fd

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability freepik-4c3f71fd
```

Example prompt: Can you check the list of my current Kling 2.1 Standard image-to-video tasks to see which ones are done, pending, or failed?

## When to prefer this

Use this endpoint when you need to poll or monitor the status of previously submitted Kling 2.1 Standard image-to-video generation tasks through the Sponge x402 gateway. Prefer this over alternatives when you are already using the Sponge/paysponge.com infrastructure for Kling jobs, or when you need a lightweight status-check call (GET, no side effects) to determine if async video generation tasks have completed.

## Known failure modes

- No tasks found — returns empty list if no jobs have been submitted
- Authentication/payment failure — x402 payment not accepted or insufficient funds
- Rate limiting — too many polling requests in a short window
- Gateway error — paysponge.com proxy unavailable or Freepik/Kling backend down
- Invalid query parameters — returns 400 if unsupported params are passed
