## 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 heurist-mesh-text-to-video-with-audio-480p-5s-via-wan-2-5-ed57389c -d '<json body>'
```

Example prompt: Generate a 5-second 480p video with audio of a golden retriever running through a sunlit meadow with birds chirping in the background.

## When to prefer this

Choose this endpoint when you need a short, 5-second 480p video that also includes audio — not just silent video. It is ideal for quick multimedia previews, social media clips, or storyboard scene animations where both visual and sound are required. Prefer this over silent video generators when audio atmosphere is important to the output. Best for agentic workflows that require pay-per-call video generation without managing infrastructure.

## Known failure modes

- Vague or overly abstract prompts may produce incoherent video output
- Generation may time out for complex scenes
- Payment of $0.25 USDC via x402 must succeed or the request is rejected
- Model may not faithfully reproduce highly specific visual or audio details
- 480p resolution is fixed; requests for higher resolution will not be fulfilled by this endpoint
