We have only tested the English language thoroughly.
We have tried other languages some work but we cannot give any reliability.
You may have to test them yourself, to check if they work for your use case.
By the way the English language that you are required to put in the query is simply there to make you acknowledge that we support English only,
it will not stop you from trying other languages.

If you have any more doubts, feel free to contact us anytime.
Thanks for trying out our API.
