Rest URL home vs. site

[dennishh]

We're having the issue that the REST API is only available via the home url, not the site url.
Unlike many other Wordpress users, we only use it as a headless CMS - the page hosted under home url is not a Wordpress, but a custom-built application. It doesn't know anything about the Wordpress API (and it should not!).
I know that this issue was rejected in https://core.trac.wordpress.org/ticket/37020, so I'm asking to either
a) add the possibility to configure the host for the API endoint or
b) give me some information on how to customize the REST API host via a plugin

Thanks in advance!

@dennishh You can use the rest_url filter to customize the returned value of the get_rest_url() function.
