## 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-08cd9c60 -d '<json body>'
```

Example prompt: Rewrite the following paragraph in a professional tone and persuasive style, and make sure the original meaning is preserved: 'Our product is pretty good and lots of people like it because it does what they need.'

## When to prefer this

Choose this endpoint when you need to transform existing text into a different tone or style rather than generating text from scratch. It is well-suited for content pipelines that need consistent voice adaptation (e.g., formalizing user-generated content, adapting blog posts for different audiences) and when meaning preservation is a priority. Prefer it over a general generation endpoint when the source text already exists and structural changes should be minimal.

## Known failure modes

- Missing required 'text' field returns validation error
- Empty string for text may produce unexpected output or error
- Ambiguous or conflicting tone/style combinations may yield inconsistent results
- Very long texts may hit token limits and be truncated
- Network timeout for unusually complex rewrites
- Insufficient USDC balance results in 402 Payment Required error
