A simple sample for retrieving the contractABI using Web3.js and Jquery to interact with a contract.

var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider());
var version = web3.version.api;

$.getJSON('https://open-platform.nodereal.io/{{APIkey}}/bsc-mainnet/contract/?action=getabi&address=0x55d398326f99059ff775485246999027b3197955', function (data) {
    var contractABI = "";
    contractABI = JSON.parse(data.result);
    if (contractABI != '') {
        var MyContract = web3.eth.contract(contractABI);
        var myContractInstance = MyContract.at("0x55d398326f99059ff775485246999027b3197955");
        var result = myContractInstance.balanceOf("0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb");
        console.log("result1 : " + result);
