Hello,
I'm sorry to hear that you've hit a problem with the TypePad API.
I'm a little confused by the question, since we've never had a "books"
endpoint for users. What data are you expecting to find at this endpoint?
Did you mean "blogs"? The endpoint /users/6p0133f5710960970b/blogs.json
is valid and will return a list of blogs for that user.
Thanks,
Martin
