怎么样通过程序来获得比特币钱包余额? (NodeJs/Python)

const axios = require('axios');

async function getBTCAddressBalance(btcAddress) {
  const url = `https://mempool.space/api/address/${btcAddress}`;

  try {
    const response = await axios.get(url);
    const { chain_stats, mempool_stats } = response.data;

    const confirmedBalance = chain_stats.funded_txo_sum - chain_stats.spent_txo_sum;
    const unconfirmedBalance = mempool_stats.funded_txo_sum - mempool_stats.spent_txo_sum;
    const totalBalance = confirmedBalance + unconfirmedBalance;

    console.log(`BTC钱包地址: ${btcAddress}`);
    console.log(`已经确认的余额: ${confirmedBalance} satoshis`);
    console.log(`未经确认的余额: ${unconfirmedBalance} satoshis`);
    console.log(`总余额: ${totalBalance} satoshis`);
    return {
        "total": totalBalance,
        "confirmedBalance": confirmedBalance,
        "unconfirmedBalance": unconfirmedBalance,
    };    
  } catch (error) {
    console.error('错误:', error.message);
    return null;
  }
