## 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`):

Example prompt: Translate this block of Simplified Chinese text into natural American English — keep all names in pinyin, preserve any numbers and dates exactly, and use the 'natural' naturalization level: '今天的会议将在下午三点开始，请各位准时出席。'

## When to prefer this

Choose this endpoint when you need Mandarin Chinese (Simplified or Traditional) translated specifically into natural American English, especially for subtitle files (SRT/WebVTT) where timing preservation is critical, or when you need line-by-line source alignment, pinyin romanization of names, and glossary compliance checking. It is purpose-built for Chinese-to-English media and drama localization workflows, unlike generic translation APIs that may not preserve subtitle formats or provide per-line source pairing.

## Known failure modes

- Input exceeds 4000 source characters — request rejected with character count error
- Non-Chinese or mixed-language input — may return partial translation or error on unsupported characters
- Malformed SRT/WebVTT format — timing parsing failure or format error returned
- Invalid naturalization level enum value — validation error
- Network timeout for large inputs near the character limit
- Glossary term not found — term returned untranslated with a flag

## How this service works

Translate Mandarin Chinese (Simplified or Traditional) into clear, natural American English: plain text by paragraph, or SRT/WebVTT subtitles returned in the same format with timings kept. Names, numbers, dates and units are kept exactly; names are romanized in pinyin. Up to 4000 source characters per call, at a chosen naturalization level (grammatical, natural, localized). Every line comes back beside its source, checked for glossary terms, untranslated characters and subtitle fit.

## Output

A structured response containing each translated line paired with its source text, the full English translation preserving original formatting (plain text by paragraph or SRT/WebVTT with timings), pinyin-romanized names, glossary term match annotations, flags for any untranslated characters, and subtitle fit warnings where applicable.
