## 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 inkbox-shift-tone-c42984fb -d '<json body>'
```

Example prompt: Rewrite this paragraph to sound casual and friendly instead of stiff and corporate: 'We regret to inform you that your request cannot be processed at this time due to insufficient account credentials.'

## When to prefer this

Choose this endpoint when you need to adjust the emotional register or stylistic voice of existing text without changing its core meaning — ideal for adapting content for different audiences, brand voices, or communication contexts. Prefer this over a general rewrite endpoint when tone is the primary variable you want to control.

## Known failure modes

- Missing required 'text' field returns validation error
- Missing required 'target_tone' field returns validation error
- Unrecognized or unsupported tone value may return an error or unexpected output
- Empty string inputs may result in empty or minimal output
- Payment failure (insufficient USDC balance) returns 402 Payment Required
- Very long text inputs may exceed token limits and fail or truncate
