## 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 minimax-h3-video-generation-api-usdc-payment-7955c107 -d '<json body>'
```

Example prompt: Generate a short AI video of a sunrise over a misty mountain range using MiniMax H3 — pay the USDC fee automatically and send me the link to track the order status.

## When to prefer this

Choose this endpoint when you need AI video generation via MiniMax H3 with a single transparent USDC pricing model and on-chain payment via x402 on Base, especially in agentic workflows that require crypto-native payments without API key management. Prefer this over traditional API-key-based video services when operating in Web3 or x402-compatible environments, or when automatic failure refunds are important for financial reliability.

## Known failure modes

- Insufficient USDC balance or missing x402 payment header — payment rejected before generation starts
- Video generation failure — MiniMax H3 model error, but USDC is automatically refunded
- Invalid or malformed prompt — request rejected with error
- Network/worker timeout on the edge worker — order may not be created
- Status URL returned but video generation stalls — requires polling to detect final failure

## How this service works

H3 API provides MiniMax H3 text-to-video, image-to-video, first-and-last-frame, and lip-sync generation with exact USDC payment over x402 on Base.

## Output

Returns a JSON object with payment settlement phase (e.g. 'settling'), a unique order ID (UUID), and a status URL path to poll for the generated video result. On failure, the USDC payment is automatically refunded.
