Lists existing Kling v3 AI video generation tasks via the Sponge x402 payment proxy

## Facts

- Endpoint: GET https://freepik.x402.paysponge.com/v1/ai/video/kling-v3
- Price: Free
- Status: down
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/freepik-d98c4eef

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-d98c4eef
```

Example prompt: Show me all my current Kling 3 video generation tasks so I can see which ones are still running or completed.

## When to prefer this

Use this endpoint when you need to poll or monitor the status of previously submitted Kling v3 video generation jobs, or when building workflows that need to check task completion before proceeding to retrieve results. Prefer over Kling 2.1 variants when working specifically with Kling v3 (the latest generation model).

## Known failure modes

- Authentication/payment failure via x402 returns 402 Payment Required
- Upstream Freepik/Kling API unavailability returns 5xx error
- Empty list returned if no tasks exist
- Rate limiting may return 429 Too Many Requests
- Invalid query parameters return 400 Bad Request
