PyPI Package Data — Metadata & Download Stats to JSON

Get clean data for any PyPI (Python) package — as JSON. Pass package names and get back a tidy row per package: latest version, summary, license, author, repository, Python requirement, dependencies and classifiers. Straight from the official PyPI API, with optional best-effort download counts. No API key, no anti-bot.

Skip scraping pypi.org — pull structured package data for dashboards, research and dependency audits.
