## 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 x402engine-minimax-h3-video-generator-4346d817 -d '<json body>'
```

Example prompt: Generate a 5-second 768p landscape video of a lone astronaut walking across a red Martian desert at golden hour, with native audio capturing the wind and distant machinery.

## When to prefer this

Choose this endpoint when you need a fixed-spec 5-second 768p landscape video with native audio generated by MiniMax H3 via a simple pay-per-call API, without managing API keys or subscriptions. Prefer it over alternatives when the 5-second duration and landscape format suit your use case and you want audio included by default.

## Known failure modes

- Prompt is empty or exceeds 2000 UTF-8 bytes — returns validation error
- Payment of $1.22 USDC not fulfilled — returns HTTP 402
- MiniMax H3 model is temporarily unavailable — returns upstream error
- Generated video URL may expire after a limited time window
- Prompt content violates content policy — request rejected
