## 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 x402-deployer-x402-deployer-workers-dev-1f3d16ff -d '<json body>'
```

Example prompt: Can you rewrite this customer complaint response in an empathetic tone, keeping it concise and aimed at a general consumer audience: 'We have received your issue and will process it per our standard SLA timeline.'

## When to prefer this

Use this endpoint when you need deterministic, tone-specific rewriting across one of 12 well-defined styles with audience and length targeting. Prefer over generic LLM prompting when you need consistent, parameterized tone control without managing prompt engineering yourself, especially in automated pipelines at $0.02 per call.

## Known failure modes

- Invalid or unsupported tone name returns an error
- Empty or missing input text causes a 400 bad request
- Text exceeds maximum character/token limit
- Payment not included or insufficient USDC results in 402 Payment Required
- Unsupported audience or length parameter values rejected
