## 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 datavault-text-expand-2b79cd7e -d '<json body>'
```

Example prompt: Can you expand this short product blurb into a detailed paragraph in a professional style, targeting around 200 words: 'Lightweight wireless headphones with 30-hour battery life and noise cancellation'?

## When to prefer this

Choose this endpoint when you need to programmatically expand short text snippets into longer prose, especially when you want control over writing style and output length. Pay-per-call USDC pricing makes it suitable for occasional or variable-volume use cases without subscription overhead.

## Known failure modes

- Missing required 'text' field returns validation error
- Invalid or unsupported style value may produce unexpected output
- Very long input text may exceed processing limits
- Payment failure via x402 protocol results in 402 response and no content
- Empty or whitespace-only text may return generic or unhelpful expansion
