Hi Particle Community,
TLDR: Today we rolled out a way to access your past account usage history, via either the API or the Console.
Hi all 
Since the launch of the new commercial model, customers have tracked their usage in the console Billing tab. One strong piece of feedback we received was to allow access to past usage reports.
Today we’ve rolled this feature out. You can access a report on your past console usage via either the Console or through an API. Users can go to their Billing & Usage tab in the Particle Console & find the section “Historical Data”.
There you can select the type of report you want (per device, per product) & how long back you want it for and it will submit a request to generate your Usage report. In short order, we will email you a CSV, detailing your device or product data operations usage over the time period requested!
If you would like to do this in a more automated fashion, check out the API here and a brief description on how you might script this here.
We’re excited to rollout this feature and hope this makes it easier for customers to view past usage and investigate their device behavior.
