The fastest solution would be to download daily dump of founded addresses (from blockchair or
http://addresses.loyce.club/ ), load into local database (for example postgresql) and then have have a program which launches queries to your database.
The fastest solution is this:
How to useThe most likely use is to check a long list of Bitcoin addresses for a remaining balance.
On Linux, use this to find matching addresses (after extrating the compressed .gz file of course):
comm -12 Bitcoin_addresses_LATEST.txt <(cat mylist.txt | sort | uniq)
- Bitcoin_addresses_LATEST.txt: the extracted latest version downloaded from addresses.loyce.club.
- mylist.txt: your own list of addresses, one address per line.
This takes only seconds to check millions of addresses. If your text file has Microsoft formatting, you may need to use this instead:
comm -12 Bitcoin_addresses_LATEST.txt <(cat mylist.txt | fromdos | sort | uniq)
Then again, that only gets you a list of funded addresses, not their balances. I'll cook something up.
I don't know exactly what you want, you ask question: how to check the balance for thousands of public addresses.
the loyce link only has data address which you can't check the address that you want.

List of all Bitcoin addresses with a balance.
