Dynamic Host for API Call

Summary:

We are planning to use VBCS for our UI layer where we are calling dyanamic host based on the input field and get the data, modify and show in tabular format. We cannot use service connection as we need to create connctions beforehand, so we are planning to call SaaS REST directly from Javascript layer but we are getting CORS error. We want to understand the best way to handle this kind of requirement and how to handle this CORS error.
