PyPI / Project metadata with every release

A Python project on PyPI: latest version, summary, long description, licence, author and maintainer, project URLs, classifiers, requires_python and requires_dist, the latest release's files and vulnerabilities, and a releases map of every version with its files. Large projects answer several hundred KB; a project over 5 MB fails at $0, use the release route then. An unknown project is a miss ($0). Free, no key: the PyPI JSON API run by the Python Software Foundation. PyPI's Acceptable Use Policy bans using the author emails in this data for spam or selling them.
