Analytics on viewers for past months

There are few restrictions to note regarding the Analytics API. Currently the stats are updated every 15 minutes of the hour (ex: XX:00, XX:15, XX:30, XX:45). Also, analytics providing a daily breakdown of your usage (Day) are stored for a window of 90 days, and the hourly data (Hour) is stored for a window of 7 days. This means you can query your data using the Day format for a maximum timeframe of the last 90 days. Hourly data is available to be queried for a maximum timeframe of last 7 days from the current day of your query. After the respective timeframes, this detailed data is purged from our system and you will then only have access to summarized monthly data.

A breakdown of per-stream data is also only available within a 7 day window. This includes geographic data as well as detailed bandwidth usage information per stream. If this detailed usage data is valuable to you, it is advised that you regularly download this data before it expires and is no longer available for querying.
