Trying To View Ethereum Balance On Goerli TestNet With ETH.Build

I'm presently trying to learn Solidity development and follow this tutorial here on build.eth:

I am using the Goerli testnet, and put Ethereum (GoerliETH) into a new wallet from a couple faucets. I can see it on Etherscan and in MetaMask.

However, when I go to hook up the components in build.eth like in the example to view the balance, I can't figure out what to put in the "[blockchain]" text field.

I tried "https://goerli.api.0x.org/" as an example, but it still shows a balance of 0. I remember I tried a couple of other addresses the other day (I can't remember where I found them), and both still showed 0 as well. I double checked my wallet address is correct and everything seems to be hooked up right.

Any idea what I should be putting into that field or something I should be doing differently?

Thanks so much.
