Rest API with NGINX?

Seems like you quoted the wrong part from .htaccess so I stand by my previous comment.
The relevant part is:

<IfModule mod_rewrite.c>
    Options -MultiViews
    RewriteEngine On
    RewriteRule api/v2/ api.php [L]
</IfModule>

This is indeed the only part in .htaccess that is about mandatory redirection and not optional protection.

Where did you put your special NGINX rewrite ?
