End Points not working

Hi ,

API end points not working. We are geting error message while using from postman or in our code.

Till yesterday(19th May 2018) everthing was working fine, But from today it is not working.
Actully I have a demo with customer for OCR Poject. So Please suggest?

I am using following Key for testing purpose.
form.Add(new StringContent(“helloworld”), “apikey”); //Added api key in form data
form.Add(new StringContent(getSelectedLanguage()), “language”);

Please suggest?
