How I get postal data by using web Api

Question

Dear Friends,

I am very beginner in the web API's segment, in my VB Aspx, I'm trying to get data by using URL: https://api.postalpincode.in/pincode/{PINCODE} (for Ex. https://api.postalpincode.in/pincode/110001)

ref input field:

<asp:TextBox ID="txt_pincode" runat="server" CssClass="form-control" TextMode="SingleLine"  placeholder="6 Number" MaxLength="6" Width="100px" ></asp:TextBox>

When the user enters 6 digit Pincode then values will bind into the dropdowns as follows...

my DropDown controls

• "Name" field should append into ddl_city
  <asp:DropDownList ID="ddl_city" runat="server" CssClass="form-control" Width="200px">
  <asp:ListItem Text="--Select--" Value="0"></asp:ListItem></asp:DropDownList>
• "District" filed values should append into ddl_district (distinct values only) <asp:DropDownList ID="ddl_district" runat="server" CssClass="form-control" Width="200px">
  <asp:ListItem Text="--Select--" Value="0"></asp:ListItem></asp:DropDownList>
• "State" filed values should append into ddl_state (distinct values only)

<asp:DropDownList ID="ddl_state" runat="server" CssClass="form-control" Width="200px">
<asp:ListItem Text="--Select--" Value="0"></asp:ListItem></asp:DropDownList>

Thanks in advance.
