This will embed the form instance in your page inside an <iframe/>. 

How do I get the url to return the form instance

...

embed java script?

First get a hold of the corresponding FormTypeEntry and then get the url as shown in the snippet below:

...

<ns:form xmlns:ns="http://www.frevvo.com/schemas/_lvxDAF_vEd2bxNL8keLevQ" 
 
         name="FormTypeAtomTest"> 
    <A>TestA</A>
    <B>TestB</B>
    <C>2013-06-30</C>
</ns:form> 

FormsService service = ...; 
NameValueCollection nvc = new NameValueCollection();
nvc.Add("_formTz", "Asia/Kolkata");


using (FileStream docStream = File.Open(@"C:\temp\_data2.xml", FileMode.Open))
{
      string id = "_LIAtYHC3EeKVINiYeE5iPA!_qrSmgInoEeKOdqjLR19yFQ!test1"; 
      FormTypeEntry formType = service.GetFormType(id);
      FormEntry form = formType.CreateFormEntry(nvc, docStream);
}

...

Using the designer, expand the Data Source pane and click the plus button to auto-generate the form controls (note that the API will be expanded to support auto generating controls).
