How can I get circulating supply and total supply for cryptocurrencies?
I am not talking about using coinmarketcap's API, I want to get the data myself. Should I get it from the source-code?

For all cryptocurrencies/altcoins? That is going to be a lot of work. There are thousands and the vast majority are effectively scams.– Michael FolksonCommented Oct 18, 2021 at 16:03

For Bitcoin you can get the total supply via gettxoutsetinfo, which produces the following output:
$ bitcoin-cli gettxoutsetinfo
{
"height": 705603,
"bestblock": "0000000000000000000173b87bcaa99c5020eb16b13a856f7015130889c5ff93",
"transactions": 45865084,
"txouts": 75262497,
"bogosize": 5632719734,
"hash_serialized_2": "ac0ce667248d97678d5eb4fcfb7e2ae667e205775765852e5b595afa73fb2eb0",
"disk_size": 4613582238,
"total_amount": 18847318.79243407
}
In the output, total_amount refers to the sum of all existing bitcoins. While other cryptocurrencies are not on-topic here, gettxoutsetinfo should also work for most Bitcoin-derived altcoins.

As mentioned in the answer, this site only covers Bitcoin, but a few other cryptocurrencies have their own stackexchange sites and you could ask there.– Murch ♦Commented Oct 19, 2021 at 11:22
