The API is going private!
After meeting with CloudFlare on Friday we came to an agreement this was the only viable option. 

To prevent any interruption of service obtain an API key and append it to ALL of your future requests.

How did it come to this? It turns out bandwidth costs money! CloudFlare has been mitigating this for us, but any option without them would merely transfer these costs to the hosting provider. The invoice image above was a two week simulated rate limiting test (that CloudFlare accidentally charged me for), which is exactly the price range I estimated for a full month $2,500-3,000+.

I need to rework all of the goals and rewards due to this change, and I hope the people dependent on this API can afford $1 a month for the time being.
