Is there an API I can use from C-Sharp?

[Al Gantori]

I would like to add diacritic marks to single words and/or small sentences at a time using a C-Sharp/.NET app.

Is there a (REST) API I can invoke like:

https://somedomain.com?text="arabic words"

which would then return some JSON

I tried the following but it did not seem to return the expected result

http://tahadz.com/mishkal/ajaxGet?text=%22%D8%A7%D9%84%D8%B3%D9%84%D8%A7%D9%85%20%D8%B9%D9%84%D9%8A%D9%83%D9%85\n%D8%A7%D9%87%D9%84%D8%A7%20%D8%A8%D9%83%D9%85\n%D9%83%D9%8A%D9%81%20%D8%AD%D8%A7%D9%84%D9%83%D9%85%22&action=%22TashkeelText%22

2nd option:
I have no experience with python, I saw mention of a mishkal python library is that callable from C-Sharp/.NET ?

Thank you.
