'Language agnostic way to get public package exports

I'm looking for language independent way to get public package exports (and other package metadata).

For example I choose some packages for java, js, php. Then I download them, analyse and get exports for each.

I've found a lot of analysers on https://analysis-tools.dev/ but I think prettiers and linters doesn't suitable for me

Do you know tools which can help me to analyse packages in this way?
