json – api in maintenance mode

Hi,

my web page is under construction (and i use plugin maintenance mode).

How i can send request e.g.:
https://mysite/api/?json=1 when is maintenance on?

If its maintenance mode off, all works properly, but when is maintenance mode on, with res client i get error (authentification).
I was try put basic authentification and set my wp login data, but nothing.

Please helm me,

BR
