I want to use my subdomains' webfonts in my main domain where can i get the request header?


You'll find examples of this and other headers for most HTTP servers in the HTML5BP Server Configs projects https://github.com/h5bp/server-configs

Nginx has to be compiled with http://wiki.nginx.org/NginxHttpHeadersModule (default on Ubuntu and some other Linux distros). Then you can do this

location ~* \.(eot|ttf|woff|woff2)$ {
    add_header Access-Control-Allow-Origin *;
