Hey Neicudi,
I’ve finally found a good online dictionary that has a usable API, which could be used to extend the import from Jisho to 12 other languages (de,el,en,es,fr,it,pl,pt,ru,sl,tr,zh). Shotgun! German goes first!
I already tested sending a GET request to their endpoint and it works!
It returns all the info you’d need to create a card; native language, foreign language, word-gender, synonyms, and even a few example sentences.
It would be a super cool feature to have, for the non-日本語 students 
Heres the link -> PONS
Happy reviewing session!

I believe I’ve taken a look at this one before (due to someone else mentioning it before). They do seem to offer other pricing models when you contact them, so I’ll send them an email to see what they can offer
