How to measure Docker Hub image pulls for free account user (reference to new policy by Docker Hub from 1. Nov 2020)?

I have two questions:

  1. As Docker Hub is updating their image pull and retention policy from 1. November 2020 and particularly restricting the image pull requests for free user account. I want to measure how many pull requests (GET) for images as well as manifests has been made by a free user account. Is there a docker hub api that gives this metadata?
  2. How to verify the docker pulled image is downloaded by a particular user?

Thank you,
