How to get Total supply of EOS?

Question

I'm curios about EOS stat data which can fetch from table using cleos get table eosio.token EOS stat.

In eos authority(https://eosauthority.com/voting), Total EOS Supply value is different from real table data (I used http://eosnetworkmonitor.io/#api).

Q1. How can I get proper value of EOS Total supply?

Q2. Which is right, cleos result or EOS Authority?

Here are captures for your convenience.

Answer 1

Should be the same, but the web interfaces lags behind due to synchronous updates, and it can also fall behind if eosauthority BP falls behind

curl --request POST \
     --url publicapi-mainnet.eosauthority.com/v1/chain/get_currency_stats \
     --data '{"symbol":"EOS","code":"eosio.token"}'

returns ~1,004,528,250 for me while front-end shows ~1,004,525,681, so a ~2,600 difference, probably due to synchronisation problems
