user3029: I'm trying to build out a Bitcoin service that requires me to query address balances and other data. So far I've been just using blockchain.info to do these request, but lately i'm hitting the too many request error. I've looked into alternatives, but many of these just went belly up over the years. Blockchain.info seems to be best long standing one that is free up to a point. Even blockstream.info has a limit.
Is there some type of locally hosted service I can just use it for the same type of query data like blockchain.info? I understand I'll need to install bitcoind and download the entire blockchain.

user85334: Blockstream.info is powered by Esplora, which is open source and reasonably easy to run yourself. You can then query that API as much as you want, with no rate limits. Note that you need quite a bit more disk space than just running Bitcoin Core.
