|Start End||Time token delimiting the start/end of time slice (exclusive) to pull messages from.|
|Count of Messages on Channels||The API is a history based API that simply does a mostly normal history operation but instead of returning the messages in a channel it returns the count of messages. Without actually calling history on those channels this API gives you the ability to say if there are messages in the chat channel you can go look at further.|

|Filter Expression||Stream Filter allows a subscriber to apply a filter to only receive messages that satisfy the conditions of the filter. The message filter is set by the subscribing client(s) but it is applied on the server side thus preventing unwanted messages (those that do not meet the conditions of the filter) from reaching the subscriber.|
