I am looking for an API, where I can get the circulating supply for all crypto currencies?
For now, I found this: https://altcoinmarketcap.com/api. The problem is that if the site go down , I can not get my circulating supply data.
Is there are more sites that can provide me API fot this data?
If I don't want to be dependant on that site, Where can I get the data?
