As part of the MetaCPAN hackathon, meta::hack, I was invited to work on the CPAN Testers integration. CPAN Testers is a community of CPAN users who send in test reports for CPAN modules as they are uploaded. MetaCPAN adds a summary of those test reports to every CPAN distribution to help you determine which module you'd most like to use. For quite a few months, this integration was broken, and the nature of the current integration (a SQLite database) means it is not as generally useful as it could be.

This API uses the CPAN Testers schema to expose CPAN Testers data using a JSON API. This API is built using the Mojolicious web framework, and an OpenAPI specification (using Mojolicious::Plugin::OpenAPI.
