dailyLimitExceededUnreg from the getgo

I'm getting a 403 forbidden response on all requests.

Is there an additional authentication step I need to make for a valid API key? I made it through their API console.

The weird thing is, I am using this package with another website made with Laravel 5.2 and it works fine, but with Lumen 5.4, it doesn't, and I have no idea why.
I have also tried tzsk/shorten-url which always return null... Is anyone facing the same problem?
