Addons Mozilla has JSON API?

Now with the availability of WebExtension is possible to upload an extension to many store but track how their success is difficult because an unique panel is missing.
So I was thinking to do a script that check on the various store the downloads, rates and review number.
Before to start to write code and prepare a data scraping script I was thinking if exist an API for AMO.
Online I cannot find anything so someone have suggestions?

PS: Yes the Chrome Web Store don’t have that API and a data scraping is the only way.

Amazing!
The endpoint in my case is https://addons.mozilla.org/api/v3/addons/addon/glotdict/ and average_daily_users is the download amount.

As I can see is missing the mime type because on Firefox Developer Edition the JSON is rendered as JSON with the new JSON view.
