You can visit this url:


It isn't exactly what you're asking for, as you don't learn versions
of the non-latest major version, but maybe that's still helpful?

I see it wasn't documented. I've just pushed docs for it:

If you want to find all of the latest versions of the
packages that planet has available, visit


It returns a list of lists of length 4. Each sublist represents
the latest version of one of the packages and contains the
userid (as a string), the package name (including ".plt"), and
the version.
