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.
Example use cases
Chinese drama subtitle localization
“I have an SRT subtitle file from a Chinese short drama — can you translate the Mandarin into natural American English, keep the timings intact, and flag any lines that might be too long for the subtitle frame?”
Business document paragraph translation
“Translate this Simplified Chinese business paragraph into clear American English at the 'localized' naturalization level, keeping all company names in pinyin and preserving the exact figures: '本季度销售额达到了2.3亿元，同比增长15%。'”
Traditional Chinese content adaptation
“Can you translate this Traditional Chinese article excerpt into grammatically correct American English? Keep all person names romanized in pinyin and check it against my glossary terms — here's the text: '隨著科技的進步，人工智慧已成為現代生活的一部分。'”

Endpoint
POSThttps://market.561.group/v1/translate/zh-en?utm_source=zero.xyzWhen to prefer
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.
Side effects
- Input exceeds 4000 source characters — request rejected with character count error

- 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
