## 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 synergy-text-rewriter-34573f94 -d '<json body>'
```

Example prompt: Rewrite the following email in a professional tone, keeping it under 150 words: 'Hey, just wanted to check in again about the invoice — we still haven't heard back and it's been like two weeks. Can you guys sort this out?'

## When to prefer this

Choose this endpoint when you need to change the tone, formality, or style of existing text without altering its meaning — for example, converting casual emails to professional ones, simplifying technical jargon, or making verbose content more concise. Prefer this over a summarization endpoint when the goal is style transformation rather than length reduction or information extraction. It is also preferable over a general-purpose LLM call when you want a cost-predictable, purpose-built rewriting service with a fixed per-call price.

## Known failure modes

- Empty or missing 'text' field returns a 400 validation error
- Invalid or unrecognized 'style' value may produce inconsistent or generic output
- 'max_words' set too low may result in truncated or incoherent output
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Very long input text may hit token limits and return a partial or error response
