Looking for a public Jenkins instance using the new Coverage Plugin (io.jenkins.plugins.coverage) for shields.io badge testing

Hi Jenkins community! :waving_hand:

I’m working on adding shields.io badge support for the new Jenkins
Coverage Plugin (io.jenkins.plugins.coverage).

To validate the implementation, I need a public Jenkins instance
that:

  • Uses the new Coverage Plugin (io.jenkins.plugins.coverage)
  • Has publicly accessible build/coverage API endpoints

I tried ci.jenkins.io but the coverage API endpoints return empty {}.

Does anyone know of a public Jenkins instance I could use for
testing? Or could someone from the Jenkins team point me to the
right job on ci.jenkins.io?

Noting Coverage Badges Extension plugin for getting that info directly from Jenkins itself
https://ci.jenkins.io/buildStatus/icon?job=Plugins%2Fcoverage-plugin%2FPR-669&status=${lineCoverage}&subject=Line%20Coverage&color=blue
So in principle the data is there on ci.jenkins.io but there is no anonymous access there
