## 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-seedance-2-mini-video-generation-ce5cb4dc -d '<json body>'
```

Example prompt: Generate a 5-second video of a golden retriever running through a sunny meadow in 16:9 aspect ratio — avoid any dark or stormy weather.

## When to prefer this

Choose this endpoint when you need pay-per-call text-to-video generation using the Seedance 2 Mini model without a subscription, especially when cost control matters ($0.57 per call), when OpenAI-compatible API format is needed, or when integrating into HermesOS or OpenClaw agent workflows. Prefer this over heavier Seedance variants when shorter videos or lower per-call cost is the priority.

## Known failure modes

- Missing required 'prompt' field returns a 400 validation error
- Invalid aspect_ratio value may cause a 422 unprocessable entity error
- Insufficient USDC payment (x402 protocol) results in a 402 payment required error
- Duration value out of supported range returns an error
- Server-side model timeout or failure returns a 500 error with status field indicating failure
- Invalid client_request_id format may be rejected
