Extracting bitcoin addresses info in batches

End goal is to find all used addresses of a xpub programmatically, in batches, by querying a local node.

This PHP tool ( https://github.com/dan-da/hd-wallet-addrs ) extracts regular bitcoin addresses from an HD bitcoin wallet . I have to query a local bitcoin node to find out whether the extracted addresses have been used or not.This can easily be found out by querying the node one address at a time ( https://bitco.in/en/developer-reference#getreceivedbyaddress ). It works, but is too slow.

How can the same be done in batches ? i.e is there a Core function call or something to check info about a group of addresses ?

or any other way this can be accomplished ? I am relatively new to bitcoin and don't fully understand its inner workings.

P.S: can't use an external API like blockchain.info

With importAddress and rescan (3 paramter) set to true, you can add the addresses that you want watch.

Than with listTransactions you can list the last transactions that affect the imported address.
