Just to be clear, package metadata already is sort of available through the pypi json api. I've got the entire set of all package metadata here: https://github.com/orf/pypi-data https://github.com/orf/pypi-data $ gzcat release_data/c/d/cdklabs.cdk-hyperledger-fabric-network.json.gz | jq '. | to_entries | .[].value.info.requires_dist' | head [ "typeguard (~=2.13.3)", "publication (>=0.0.3)", "jsii (<2.0.0,>=1.63.2)", "constructs (<11.0.0,>=10.0.5)", "aws-cdk-lib (<3.0.0,>=2.33.0)" ] It's just not everything has it, and there isn't a way to differenciate between "missing" and "no dependencies". And it's also only for the `dist` releases. But anyway, poetry uses this information during dependency resolution.
