Re: Are there REST or SOAP APIs available to embed the Unified Digital Profile within a CRM application similar to "My bestbets" within SalesForce?
I'm a little thrown off by your use of the term "UDP" because I do not consider Marketo a UDP repository. If your question is, "Is there an API that can return a pre-formatted HTML block or document corresponding to a Marketo lead," then no, there is no such API. However if someone is logged into Mkto you could iframe the lead detail page. I think you need to be more clear about your UI and API goals.
