HTML to call wp.getPost in the WordPress XMLRPC API

I need HTML written to call wp_getPost. [login to view URL] [ blog_id, username, password, post_id ] [login to view URL] This is just an initial proof of concept. I will ask for more if you can make this work. A lot more. Implementation of the entire WordPress XMLRPC API in the same fashion. You can use PHP or Javascript but here is the primary constraint: NO LIBRARIES. Everything must be contained within a single HTML page. Nothing can be external to that code. If hosting a library on a webpage (external to the webpage this is being called for) would work, then we can do that. That's it though and you'll need to show me how to do that. You can hardcode in the parameters. I will provide a sample blog_id, username, password and post_id once you've accepted the project.
