 TODO: API RATE LIMITING / THROTTLING
+	- Return code 429 
 	- Going to need rate limiting to save people from themselves 
 	- All the big api's have hourly limits on requests and also limits on total data throughput per hour 
 	- (minute as well which actually makes more sense since it means they would only be down for a minute if they exceed it) too
+	- Find out what others do
