PyPI Registry API

healthy 4,577 Subscribers

Python package data from PyPI as clean JSON. Look up any package’s latest metadata — version, summary, license, repository, author, keywords, required Python version, dependencies, supported Python versions and total release count — browse its full version history with release dates and yanked flags, or get the details and distribution files for one specific version. Sourced live from the public Python Package Index and returned through a fast, reliable API. Ideal for developer dashboards and tooling, package and dependency analytics, security and supply-chain checks, CI/CD and documentation sites.

PyPI Download Stats API

Live PyPI (Python Package Index) download analytics from pypistats.org — no key, nothing stored. The adoption view of a Python package: how much it is downloaded, the daily trend, and the breakdown by Python version and operating system, distinct from the PyPI registry-metadata API in the catalogue (which describes a package — this measures how much the community actually uses it). The recent endpoint returns the headline download counts: last day, last week and last month. The overall endpoint returns the daily download timeline so you can chart growth. The python endpoint breaks downloads down by Python version, showing which versions the package's users are actually on. The system endpoint breaks downloads down by operating system — Linux, Windows and macOS. Build package-popularity dashboards, dependency-adoption trackers, "which Python version should we still support" tools and ecosystem-trend widgets on top of real PyPI download data. Look up any package by its PyPI name (requests, numpy, flask); names are normalised to lowercase and the version and system splits include each category's share of total downloads.

Homebrew Install Analytics API

Live install analytics for Homebrew, the macOS and Linux package manager, from the public formulae.brew.sh feed — no key, nothing stored. The adoption view of the Homebrew ecosystem: how much each command-line formula and each desktop-app cask is installed, and the most-installed packages overall, distinct from the Homebrew formula-catalog API in the catalogue (which describes a package — this measures how much it is actually used). The formula endpoint returns a command-line tool's install counts over 30, 90 and 365 days plus install-on-request, with its version and description. The cask endpoint returns a desktop app's install counts. The top endpoint returns the most-installed formulae or casks over a chosen window, ranked. Build developer-tool popularity dashboards, "is this tool still maintained and used" widgets, package-trend trackers and ecosystem-health tools on top of real Homebrew analytics. Look up a formula by its name (wget, node, ffmpeg) or a cask by its token (google-chrome, visual-studio-code); counts come from Homebrew's opted-in user analytics.

AUR API

The Arch User Repository (AUR) as an API. Look up any AUR package for its version, description, upstream URL, maintainer and submitter, community votes and popularity score, license, out-of-date flag, keywords and full dependency lists (depends, make-depends, opt-depends), plus its source snapshot and ready-to-run git-clone command; search the whole AUR by name, description, maintainer, dependencies or keywords (results sorted by popularity); and list every package maintained by a given user. Covers the 90,000+ community-maintained packages of Arch Linux, from yay, paru and visual-studio-code-bin to google-chrome and spotify. Live from the official AUR RPC. Ideal for Arch/AUR helpers and dashboards, package and dependency tooling, and Linux developer portals. Open data from the Arch User Repository.

Homebrew API

The macOS and Linux package manager — Homebrew (brew) — as an API. Look up any formula (command-line package) for its description, latest version, license, homepage, dependencies and build dependencies, caveats and deprecation status; look up any cask (graphical macOS app) for its version, bundled apps and homepage; and search the whole registry of 8,300+ formulae and 7,600+ casks by name and description. Each result comes with the exact `brew install` command. Covers the Homebrew world from wget, git, ffmpeg, node and python to Firefox, Visual Studio Code, Docker and Rectangle. Live from the official formulae.brew.sh API. Ideal for developer dashboards, package and dependency tooling, dotfiles and setup automation, and macOS app catalogs. Open data from Homebrew.
