    The Packagist API exposes the public PHP Composer package registry — over 454,000 packages and
    5.58 million versions backing more than 181 billion installs since 2012. Read endpoints (list,
    search, popular, package detail, Composer v2 metadata, change feed, statistics, security advisories)
    are anonymous; write endpoints (create-package, edit-package, update-package) authenticate with
    SAFE or MAIN API tokens via Bearer `username:apiToken`. Static Composer v2 metadata is served from
    a separate high-throughput mirror at repo.packagist.org.

  Packagist is the default package repository for Composer, the PHP dependency manager. It indexes
  over 454,000 open-source PHP packages — versions, dependencies, maintainers, download statistics,
  security advisories — and exposes them through a free public HTTP API plus a high-throughput static
  Composer v2 metadata mirror at repo.packagist.org. Packagist is MIT-licensed open source (composer/packagist
  on GitHub) and is operated by the Composer team, with funding from Private Packagist (the commercial
  hosted/self-hosted sibling product at packagist.com) and infrastructure sponsorships from Bunny.net
  and Aikido. Together with the Composer CLI, the SemVer library, the SPDX licenses helper, and the
  Satis static repository generator, Packagist anchors PHP's modern software supply chain.
