Bittrex: What Error Do You Receive for Spamming the API? I have a script which queries the Bittrex API pretty frequently (it makes an order after the previous order has filled).

This question asks about the rate limits. Therein, it is mentioned that Bittrex is rather dodgy about the rate limits, and they could change over time. 

I want to know what the error/warning response for spamming the API is so I can slow down my requests adaptively (and therefore, not need to edit my script if they change the rate limit in the future).

Does anyone know what the error/warning response for spamming the API is?
It isn't clear from Bittrex what error message is received when you encounter a limit. They just say that the request will fail. According the latest information from Bittrex Accounts can query the API up to 60-times a minute, once per second.

That said, there is a "success" flag returned for every request to the Bittrex API. I would imagine that this would be "false" and there would be some sort of message explaining the error. Maybe just look for false?
