Using DeepL API to translate text

dontbyteme picture dontbyteme · Aug 29, 2017 · Viewed 15.8k times · Source

Is there any possibility to find out if the DeepL translator offers an API for the translation? Unfortunately I haven't found any information on this.

Would like to implement this to an Excel script for auto translation. I've already tried it with Google (like https://translate.google.com/#en/es/Hello%20World) but DeepL seems more accurate.

There is a POST call that allows you get the translations, I don't know how many time this will be supported or it's times limitations but here it is:

Url: https://www.deepl.com/jsonrpc

You should make a POST call with the next json:

{
        'jsonrpc': '2.0',
        'method': 'LMT_handle_jobs',
        'params': {
            'jobs': [
                {
                    'kind':'default',
                    'raw_en_sentence': TEXT_TO_TRANSLATE
                }
            ],
            'lang': {
                'user_preferred_langs': [
                    FROM_LANGUAGE,
                    TO_LANGUAGE
                ],
                'source_lang_user_selected': FROM_LANGUAGE,
                'target_lang': TO_LANGUAGE
            },
            'priority': -1
        },
}

The available languages are:

auto  Auto detect
DE    German
EN    English
FR    French
ES    Spanish
IT    Italian
NL    Dutch
PL    Polish

TO_LANGUAGE must be a valid language and FROM_LANGUAGE can be a valid language or auto

I wrote a python module that wraps this API: pydeepl There are currently also a node package and a php client that accomplish the same goal.
