## 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-e345adc1
```

Example prompt: Show me all my Veo 3.1 reference-to-video tasks on Sponge so I can check which ones have finished and see their results.

## When to prefer this

Use this endpoint when you need to retrieve the full list of previously submitted Veo 3.1 Reference-to-Video generation jobs, especially to check status, poll for completion, or audit past tasks. Prefer over text-to-video list endpoints when your workflow used a reference image or video as input to Veo 3.1.

## Known failure modes

- Authentication failure if x402 payment headers are missing or invalid (402 Payment Required)
- Empty list returned if no tasks have been submitted yet
- Rate limiting or quota exceeded errors
- Service unavailability from the underlying Freepik/Veo 3.1 backend
- Malformed response if upstream provider API changes
