Once you installed the packages, you can use them to call ZAP Contracts :
// Example with @zapjs/provider package to create Oracle
import {ZapProvider} from "@zapjs/provider"
import * as Web3 from "web3"
const myWeb3 = new Web3("nodeURL")
const newOracle = new ZapProvider(yourAddress,{networkId:1,networkProvider:myWeb3})
