## 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 imgnai-katana-api-google-omni-video-generation-7d24ebb3 -d '<json body>'
```

Example prompt: Generate a 10-second widescreen (16:9) AI video of a serene mountain lake at sunset with gentle ripples using Google Omni — no people or urban elements.

## When to prefer this

Choose this endpoint when you specifically need Google Omni video generation via a pay-per-call x402 micropayment model without a subscription, or when integrating into an OpenAPI/HermesOS/OpenClaw-compatible agent workflow that needs text-to-video at ~$0.52 per call.

## Known failure modes

- Missing required 'prompt' field returns validation error
- Invalid aspect_ratio format causes rejection
- Insufficient USDC balance triggers payment failure (x402)
- Duration value out of supported range causes error
- Model unavailability or upstream Google Omni outage returns error status
- Prompt violates content policy and is rejected
