Describe all registered entities (xml)

General notes on special params and headers:
no-cache - this will cause the caching headers to be set for no caching (default caching is set based on last modified date on entity OR 5 minutes)
last-modified - this will force the last-modified date header to be set (unix timestamp in ms), no-cache overrides this
accept - this standard header can be used in place of format extensions (e.g. xml), just leave the extension off the URL

When searching for entities in a list, the following params are handled specially in the system (note that all the RoR conventions are followed for sorting/paging):
_start (number): the position of the first entity to return (0 is the first), e.g. _start=5
_page (number): the page of data to display (0 is first), e.g. _page=2
_perpage (number): the number of entities to return for the page (0 means all), e.g. _perpage=20
_limit (number): the maximum number of entities to return (0 means all), e.g. _limit=50
_order (string): the sort order to return entities in (default is ascending), should be a comma separated list of entity field names which optionally include a suffix to determine order, suffix can be _reverse or _desc for descending order OR '' (blank) or _asc for ascending order, e.g. _order=name OR _order=name_reverse OR _order=name,email_desc,firstname_asc,lastname_reverse
_sort (string): same as order
_validateSession: supply this parameter if sessions are to be explicitly checked to ensure a valid session. Without this, the session validation is left to the provider

There are two optional URL parameters available: 'n' to set the total number of announcements returned, and 'd' to set the number of days in the past to retrieve announcements for. If these parameters are not set, they are retrieved from the tool configuration, or the standard defaults of n=3 and d=10 are used. For example /announcements/site/mercury.json?n=20&d=100 will retrieve up to 20 total announcements for up to 100 days ago.

After that you would use /direct/forums/site/SITEID/forum/FORUMID/topic/TOPICID.json to get a topic, basicallya set of conversations, then you would call /direct/forums/site/SITEID/forum/FORUMID/topic/TOPICID/message/MESSAGEID.json to get a fully populated message with attachments and children.
