Taken from their FAQ[1]:

Quote
Circulating Supply is the best approximation of the number of coins that are circulating in the market and in the general public's hands.
Total Supply is the total amount of coins in existence right now (minus any coins that have been verifiably burned).
Max Supply the best approximation of the maximum amount of coins that will ever exist in the lifetime of the cryptocurrency.

Why does the supply number sometimes appear grayed out?
- A grayed out supply number indicates that the data source for the supply has gone stale for at least seven days and might not be up to date.

Technical informations are manually inserted with every coin they add.
And other informations related to price are gathered from several exchanges APIs.

They take the prices of a coin from the exchanges and multiple it with the total amount of coins mined. Pretty simple.

Any Idea how they get the total amount of coin mined?

I want to get the data directly and not from thier API.

Thanks

They may run versions of the coins wallet and a simple call to the wallet will give you the parameter "moneysupply" which is the number of coins currently in existence on that chain.

Something like that.

coinmarketcap.com uses API exchanges
Go to https://coinmarketcap.com/currencies/bitcoin/#Markets
You see a list of exchanges that trade bitcoin.
All these exchanges have their own API, through which you can receive data.
And already with these data you can make a similar site.

Coinmarketcap(dot)com provides different types of supply for different cryptocurrencies. Broadly there are 3 types of supply provided by cryptocurrency listing cites such as coinmarketcap(dot)com.

Circulating supply: Circulating supply is the amount of coin available at the present time and circulating in the market.

Total supply: Total supply is the amount of coin that is already in existence. However, not all of the coins may be circulating at the present time. Generally, total supply is equal to or greater than the circulating supply.

Maximum supply: Maximum supply is the amount of coin that will ever exist for that particular cryptocurrency. For example, Bitcoins max supply is 21 million BTC.

I highly doubt that they use these APIs to retrieve a currency's circulating/total supply.

            Important factors to bear in mind before investing in any cryptocurrency is to find out the coin supply.Circulating supply is the amount of coin available at the present time and circulating in the market.Total supply is the amount of coin that is already in existence.Not
all the coin may be circulating at the present time.Generally total supply is equal to or greater than the circulating supply. If a cryptocurrency has
only the circulating supply and does not have total supply or max supply,that means that cryptocurrency has circulating supply and total supply but does not have max supply that means no maximum cap on that coin.In Etherum, monera etc, they only have circulating supply information because their supply is infinite.

All the data you need from practically every single crypto currency is stored on coinmarketcap.com (bookmark it, you're going to need it if you are serious about crypto currency). For me the total supply and the circulating supply are a big factor when I do a fundamental analysis.

Seems nobody answered this question perfectly. Each cryptocurrency has a dedicated block explorer like Iquidus Explorer who has an API function. Thanks to this API function, Coinmarketcap calls the API of the dedicated block explorer and changes the available information in the database vice-versa to the site.

"Circulating supply" is not that easy.  The larger trades (early adopters, institutional, etc....) are handled using OTC and Dark Pool mechanisms.  They are not funneled through public exchanges.  Frankly, those transactions out value the daily trades the public exchanges handle.  They move thousands or tens of thousands of coins per transaction and they way they do it doesn't move the price needle mid transaction due to sucking the demand curve.

Coinmarketcap gets it's data from users manually uploading it. Coinmarketcap then checks block explorers or etherscan to verify if it is right or not.
As far as I am aware, they only use API's for the larger cryptos like bitcoin, ethereum etc.

I'm not too sure about other sites.

For max supply, the only way to be sure is by reading the code. Especially with alts, which are under development, where the core team basically makes all the decisions and are decentralized only in aspiration, the inflation and max supply can change in a single commit.

I am not sure how circulating supply is derived.
