## 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 tempest-ai-content-engine-rewrite-8324791e -d '<json body>'
```

Example prompt: Can you rewrite the following paragraph in a confident, persuasive tone with a professional style, and make sure you keep the original meaning intact: 'Our software helps teams work together by sharing files and tracking tasks in one place.'

## When to prefer this

Choose this endpoint when you need to rephrase or stylistically transform existing text rather than generate new content from scratch, especially when tone or style targeting is important and meaning preservation is desired. Best for copywriting, content editing, and audience-adaptation workflows.

## Known failure modes

- Missing required 'text' field returns a 400 or error response
- Invalid tone or style values may produce unexpected output
- Very long text inputs may exceed processing limits
- Payment failure via x402 results in a 402 response and no content returned
- Network timeout on Vercel serverless function for large payloads
