I was looking at feeds.chain.link and it's not immediately obvious if anyone can tap into all these price feeds without incurring a cost:
For instance, I did find the ETH/USD aggregator contract, which has a "latestAnswer" property that anyone can access for free. At the time of posting this question, its value is 37867000000 (1 ETH = $378.67).
Is there an aggregator for all pairs listed on feeds.chain.link?
