The API uses three different levels of authentication, depending on the method. None: No authentication. Anybody can query the method. API key: Requires an API key. Use your OAuth Consumer Key as your api_key. OAuth: Requires a signed request that meets the OAuth 1.0a Protocol.

reblog_info and notes_info are false by default because of the server impact involved in retrieving the data.
