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.
The REST API is finally (commercially) available, see the API reference documentation.
A sample request would be
https://api.deepl.com/v1/translate?text=Hello%20World!&target_lang=EN&auth_key=XXX
where XXX is the authentication key you need to register with DeepL.
