Hey! Sorry for the slow reply.

For most bits of data, yes. Although I haven't used limit/offset style
pagination as that doesn't perform particularly well.

The Guix Data Service web pages should help with how to use the API, so
you can look at how the packages page handles pagination for example:

  
https://data.guix.gnu.org/revision/c4025af8c11c3e9ea0c2747b6c475c916fb61d80/packages

You can get a count here for example [1], that also works with the
latest-processed-revision URL [2]. I think the counting methadolody is a
bit different to what's currently used though.

1: 
https://data.guix.gnu.org/revision/c4025af8c11c3e9ea0c2747b6c475c916fb61d80.json
2: 
https://data.guix.gnu.org/repository/1/branch/master/latest-processed-revision.json

> 3. Is there any way to get the "supported-systems" info of a package?

The value of that specific field isn't recorded, but you could look at
the derivations of the package, then just find the systems, that should
be pretty close:

  
https://data.guix.gnu.org/revision/c4025af8c11c3e9ea0c2747b6c475c916fb61d80/package/0ad/0.0.26-alpha.json

Thanks,
