jsDelivr
jsDelivr's data API (`data.jsdelivr.com`) returns JSON metadata for any package it serves — versions, entry points, file trees, and download-count stats for npm and GitHub-hosted projects — alongside the free asset CDN itself, which pulls files from npm and GitHub and fronts them with Fastly, Cloudflare, and other sponsor networks. Both the CDN and the data API are free with no signup, no bandwidth limits, and no rate limiting for normal use; the project is sustained entirely by CDN sponsors rather than paid plans.
