The API of the Toolforge toolviews program should be able to return hits for all dates for a specific tool.
|T166406 Program 10 Outcome 3: Outreach
|T176677 Promote Toolforge Tools and their maintainers within Wikimedia communities
|T178834 Provide any rough metrics for tool and project usage
|T129630 Collect and display basic metrics for all tools (service groups)
|T87001 Provide basic page view metrics for individual tools on toolforge
|T227120 Toolforge toolviews API could return views for all dates
I added an API endpoint that will give daily hit counts for a given tool between a start and end date: https://tools.wmflabs.org/toolviews/api/v1/tool/sal/daily/2019-06-01/2019-06-30
I don't recommend or encourage it, but this can be used to list "all" dates by choosing the start and end dates to be at extremes.
