Nginx alias configuration for API with Silex

I have a problem with NGinx configuration, I know that there are many topics, but I was not able to work normally ...

So, I have mydomain.com and mydomain.com/api/, my folders are similar to: /var/www/mydomain.com/website/dist and /var/www/mydomain.com/api/public

And at the moment, something almost works for me. But index.php still gets the / api part on my routes.

server {
    listen 80;
    server_name mydomain.com www.mydomain.com;

    index index.php index.html;

    location / {
        root /var/www/mydomain.com/website/dist;
    }

    location ~ ^/api(/|$) {
        root /var/www/mydomain.com/api/public;
        try_files $uri /api/index.php;

        location ~ \.php$ {
            try_files $uri /index.php =404;

            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_index           index.php;
            fastcgi_pass            unix:/tmp/php5-fpm.sock;
            include                 fastcgi_params;
            fastcgi_param           SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param           APPLICATION_ENV production;
        }

        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Allow-Headers' 'X-Requested-With,Content-Type,Authorization';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS';
    }

    access_log /var/logs/nginx/logs/mydomain.com-access.log;
    error_log /var/logs/nginx/logs/mydomain.com-error.log;
}
