Developer Resources

We hope that developers make use of the APIs and tools that we have built for PMC.

In this page, we list the APIs and public code repositories related to PMC. We also present some of the most common developer questions, and provide instructions and examples for addressing them in subsequent pages.


The use of our APIs is entirely free, and doesn't require an API key, but we ask that you please:

  • Do not make concurrent requests, even at off-peak times; and

  • Include two parameters that help to identify your service or application to our servers:

    • tool should be the name of the application, as a string value with no internal spaces, and
    • email should be the e-mail address of the maintainer of the tool, and should be a valid e-mail address.

    For the sake of readability, these parameters have been omitted from the on-screen display of the URLs in the example pages.

Here is a list of APIs that can be used to get data about PMC resources.
