Language Translation API

Language Translation API

Translate any given text from and between 47 languages (IBM Watson).

The IBM Watson Language Translator service converts text input in one language into a destination language for the end user using background from domain-specific models. Translation is available among Arabic, Catalan, Chinese (Simplified and Traditional), Czech, Danish, Dutch, English, Finnish, French, German, Hindi, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish and Turkish (some languages may not be available for all domains).

By default all language pairs leverage neural machine translation. This new technology uses deep learning to improve translation speed and accuracy.

curl --location --request POST '' \
--header 'apikey: YOUR API KEY' \
--data-raw 'We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.'
