Text Translation API

About this tool

Instantly translate text between 100+ languages. Supports automatic source language detection — just set source_lang: "auto". The API tries LibreTranslate first, falls back to MyMemory, then Google Translate. Returns the translated text, detected language, and which provider was used. Accepts both target_lang and legacy to params.
