rest_url() │ WP 4.4.0

Gets the REST API URL for the current site. You can specify a specific route.

Differs from get_rest_url() in that there is no option to specify the site ID of the network here, while there is there.

The returned URL is not sanitized for output. Therefore, use the function esc_url() before outputting.

Uses: get_rest_url(), rest_get_url_prefix()
