I'm making a client app that will display a wordpress blog (outside of the browser) and show comments, TOC, etc. I would like to be able to use XML-RPC to get all the information rather than scrape it from the HTML. From what I can tell, the XML-RPC interface requires a wordpress login even to retrieve information.
Is there a public username/password that can be used just to retreive information and be locked out of making any changes?
If not, can I create a user account with the sole purpose of retreiving information from blogs via XML-RPC? I intend to make the user login with their own information if they wanted to post comments, but I would like to avoid forcing them to sign up for wordpress just to read the blog through my app. I would use SSL to encrypt the info and the "public" login information would never be revealed to the user of the app.
