## 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 glianaai-veo-3-1-fast-video-generation-342ace4d
```

Example prompt: Use Veo 3.1 Fast to generate a short video of a golden retriever running through a field of sunflowers at sunset, and pay the $2.25 USDC fee automatically.

## When to prefer this

Choose this endpoint when you need fast, high-quality AI video generation from text using Google's Veo 3.1 Fast model, want pay-per-call billing in USDC with no signup or subscription, and are operating in an agentic context where x402 micropayment is supported. Prefer this over subscription-based video APIs when cost per call matters and you need Google Veo quality without managing API keys.

## Known failure modes

- Model overload or timeout returns a 503 or 504 error
- Prompt policy violation (NSFW, harmful content) returns a 400 or 403 error
