xmlrpc

I have an xmlrpc.php hyperlink that shows as hidden and broken on all pages in the background of my WordPress sites.
Wondering if we need it? I believe it’s in the htaccess folder and hoping there is a way to delete it if it is not necessary? Would prefer not to use a plugin.

Found this code to hide/block it but it did not seem to work:

# Block WordPress xmlrpc.php requests
<Files xmlrpc.php>
order deny,allow
deny from all
</Files>

Have not had luck getting a hold of the theme developer. Please let me know any thoughts. Thank you!
