## 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-wanvideogenagent-text-to-video-with-audio-480p-5s-9efb8592 -d '<json body>'
```

Example prompt: Create a 5-second 480p video with audio of a golden retriever running through a sunlit field of flowers, and go ahead and enhance the prompt automatically.

## When to prefer this

Choose this endpoint when you need a short AI-generated video clip (5 seconds, 480p) that includes audio, produced directly from a text description. It is ideal for rapid prototyping of video content, social media clips, or demonstration videos where a quick turnaround on a budget ($0.25) matters. Prefer this over image-only generation when motion and sound are required together.

## Known failure modes

- Invalid or empty prompt returns validation error
- Prompt too long or unsupported content triggers rejection
- Model timeout or inference failure returns server error
- Payment of $0.25 USDC not completed results in 402 Payment Required
- Debug mode left true may alter output or expose internal state
