Excited to share that I made a new API for the Plugin Check (PCP) reviews of plugins. Right now it's launched only for use by the spreadsheet plugins here: https://comparewp.org/cck/

It runs once a week, checks the latest version of the plugin for errors+warnings (full suite) and stores that for the API to consume. The API exposes just the total error + warning numbers at the moment.

Examples:
https://comparewp.org/plugin-check-api/pods/
https://comparewp.org/plugin-check-api/advanced-custom-fields/

The sheet above has a row that now shows those counts.
