Today, BitcoinAverage has silently stopped supporting "unauthenticated" requests to its API, unexpectedly breaking my entire system that relied on this data. I have used them for a long time to get the current price of Bitcoin in various fiat currencies. The requests now come back all:
Unauthenticated requests are not allowed. Sign up for a new plan or get started

I am not creating an account to benefit from a "free trial". They want now at least TWELVE BUCKS PER MONTH so I can just freak out keeping track of Bitcoin value: https://bitcoinaverage.com/en/plans
I don't even pay nearly $ 12 in total each month for all of my "crucial Internet services" … What do they think I am? Some kind of rich person? If I were to bring in money, it would be a whole different matter – then I would be happy to buy their most expensive plan and not think twice about it. But this is not the case. I don't make a dime. Unfortunately.
Is there a stable and non-greedy API from which I can freely enter the current value USD => BTC (or EUR or GBP, etc.)?
