Integrate API to Android || Grammar Check

I am developing a mobile application where the app, gives a word to the user, the user speaks a sentence using the word and the app returns if the statement was grammatically correct or not, and if wrong, what could be the right possible answer.
Could I make use of langauagetool and would a premium version be needed?

Hi, you could just try Public HTTP Proofreading API - LanguageTool Wiki if the limits are okay for you.
