Limits

These routes are request and response shape adapters, not full vendor feature parity. Google v3 custom model, glossaryConfig, and transliterationConfig are currently unsupported.
The Microsoft Translator compatibility translate route accepts up to 16 text items, up to 10 repeated to targets, optional from, and textType=plain|html.
Microsoft transliteration and dictionary routes (transliterate, dictionary/lookup, dictionary/examples) are not implemented and return 501.
For new integrations, prefer the native Lexel endpoints and canonical language tags from Languages.
The implemented Google compatibility surface includes both v2-style routes and the Google v3 wrapper route for translateText, detectLanguage, and supportedLanguages.
The Microsoft Translator Text v3 surface includes translate, detect, breaksentence, and the translation language catalog.
