Endpoint
GEThttps://api.cn402.com/hanzi/pinyinWhen to prefer
Use this endpoint when you need accurate Hanyu Pinyin romanization with proper tone marks for Chinese (Mandarin) text — ideal for text-to-speech pipelines, language learning apps, pronunciation guides, or annotating Chinese content for non-native readers. Prefer this over generic translation APIs when you specifically need phonetic output rather than meaning translation.

- Invalid or malformed characters may not be converted
- Network timeout for very long text inputs
- HTTP 402 if payment header is missing or insufficient
