## 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 deepl-write-via-locus-x402-2ec189fc -d '<json body>'
```

Example prompt: Can you use DeepL Write to rephrase this paragraph to sound more confident and business-like in US English: 'We are not sure if we can meet the deadline, but we will try our best to deliver the project on time'?

## When to prefer this

Choose this endpoint when you need to improve, polish, or rephrase existing text — not translate it — and you want fine-grained control over tone (enthusiastic, confident, diplomatic, friendly) and writing style (academic, business, casual, simple). It is ideal when the user already has text in one of the 8 supported languages and wants it to sound better, not when they need to convert between languages. Prefer the sibling translate endpoint for cross-language work.

## Known failure modes

- Unsupported target_lang value — only 8 specific language codes are accepted (de, en-US, en-GB, es, fr, it, pt-BR, pt-PT)
- Invalid tone or writing_style enum value causes request rejection
- Empty or null text array returns an error
- Payment failure or insufficient USDC balance prevents processing
- Rate limiting or DeepL API downtime results in 5xx errors
- Very long text inputs may exceed DeepL's per-request character limits

## Output

Returns a JSON object with the improved/rephrased text(s) produced by DeepL Write, along with payment settlement details (amount of USDC charged), a unique request ID, a status URL for tracking, and a success flag. The rephrased text reflects the requested tone and writing style.
