## 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 orbonomy-shift-tone-api-5ff28b06 -d '<json body>'
```

Example prompt: Can you rewrite the following paragraph in a formal tone? 'Hey, just wanted to check in and see if you had a chance to look at the proposal we sent over last week — totally understand if you've been busy!'

## When to prefer this

Use this endpoint when you need a fast, pay-per-call tone transformation for arbitrary text and want to avoid setting up a full LLM pipeline yourself. Ideal for workflows requiring automated copy adaptation across different audiences or communication styles.

## Known failure modes

- Missing required 'text' or 'tone' fields returns a validation error
