Api through ajax call not working

[AlishaMathur]

Hello team, 

I want to do some customization on my site. 
I want to fetch specific customers on frontend through apis, but when i call its shows error 
Access to XMLHttpRequest at from origin has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Please give any solution regarding this or any other method to call customers on frontend.

That's a CORS error. What URL are you posting to, and if it's local on your machine, is your development environment configured correctly?
