B4J Question a b4x code where api keys are used and get data from an API

' Main module
Sub Process_Globals
    Public Const API_URL As String = "https://api.quantumnumbers.anu.edu.au"
    Public Const API_KEY As String = "your_secret_api_key"
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    ' Initialize the form
    MainForm = Form1
    MainForm.Show
   
    ' Example parameters
    Dim arrayLength As Int = 10
    Dim dataType As String = "hex16"
    Dim blockSize As Int = 1
   
    ' Call the function to fetch data
    FetchQuantumNumbers(arrayLength, dataType, blockSize)
End Sub

Sub FetchQuantumNumbers(arrayLength As Int, dataType As String, blockSize As Int)
    Dim url As String = $"${API_URL}?length=${arrayLength}&type=${dataType}&size=${blockSize}"$
   
    Dim Job As HttpJob
    Job.Initialize("QuantumNumbersJob", Me)
    Job.GetRequest.SetHeader("x-api-key", API_KEY)
    Job.Download(url)
   
    ' Wait for the job to complete
    Wait For (Job) JobDone(Job As HttpJob)
   
    If Job.Success Then
