Taking Ethereum as an example, you can interact with the Ethereum blockchain using the Web3.js library. First, you need to install and import the Web3.js library, then connect to an Ethereum node, such as Infura. Next, you can query the remaining computation units by calling contract methods on the blockchain or by writing custom functions using smart contracts. Specifically, you can create a function  that receives an address as a parameter, and queries the balance and used computation units of that address."}]}],"pr":"45b6446179d44d018cc160157c0e0beb0953aef1208a696fe377467732b999a6"}
