How this service works
PyPI package facts: version, license, Python requirement, release date — Genesis402 / UnyKorn Operator Network
Output
Returns a structured object with the package's latest version string, SPDX license identifier, minimum Python version requirement (e.g. '>=3.8'), and the release date of the latest version.
Example use cases
Dependency audit for a Python project
“Can you look up the license and Python version requirement for 'pydantic' on PyPI? I need to check if it's compatible with our project.”
Check if a package is actively maintained
“When was the latest release of 'celery' on PyPI? I want to know if it's been updated recently before we add it as a dependency.”
Verify package version before pinning
“What's the current version of 'boto3' on PyPI so I can pin it in our requirements.txt?”
