API Key blocked, sorta?

I'm working on a rails app that uses character data, which I wanted to get from the ComicVine API. When I attempt to make calls to the API from within the app, they fail and I'm told my API key is invalid. However, if I type them out in browser and test the calls, they work just fine with my key. On the dashboard, however, it appears that the calls are making it through as it's counting them against my rate limit.

Can anyone help?

@cotarg: Sorry it took so long to respond, some of the queries you are making are taking a very long time to execute and are timing out. We are looking into the issue

@wcarle - Awesome, thank you so much.

I'm using caching and a couple of work arounds for now, but I'll keep an eye on this!

(And once this app is done, I'll even link to it. :) )

Thanks again!
