## 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-93b0cf8d -d '<json body>'
```

Example prompt: Can you expand this short product description into a longer, more detailed version in a professional style, aiming for a long target length: 'Ergonomic office chair with lumbar support and adjustable armrests.'

## When to prefer this

Choose this endpoint when you need to programmatically lengthen, elaborate, or enrich short text inputs into fuller content, especially when you want control over style and target length and are comfortable with pay-per-call USDC micropayments on Base

## Known failure modes

- Missing required 'text' field returns a validation error
- Very long input text may be truncated or rejected
- Invalid or unrecognized style values may be ignored or cause errors
- Service unavailability returns a 402 or 5xx response
- Insufficient USDC balance causes payment failure and no content returned
