API for large number of queries to different addresses every few minutes

Bitcoin Asked on January 2, 2022

I have an application that needs to makes queries to get address balances and transaction data from Bitcoin.

What are some possible solutions to this? It would be great if I didn’t have to manage a full node if possible.

One Answer

You can use a self-hosted (but low-burden!) instance of Esplora.

Blockstream is also exposing an instance for free (at the moment) at

Disclaimer: if you take part of Bitcoin as an economic actor (as an application providing account balances may imply), you should really consider using your own source of truth and self-host the instance. It's just a docker to start and an nginx reverse proxy to set up after all :-).
