Sadly, no. The metadata available for packages on PyPI does not include
information about the dependencies.

(I'd love to be wrong about that, but I'm pretty certain that for most,
if not all, packages that's the case.)

All the solutions I've seen involve fetching the full package in order
to unpack it and *then* parse it for dependencies.

This is very sub-optimal, and I believe people are working on it; but
fixing it will at least require adjustment to all existing packages that
don't have dependencies in their metadata.
