RubyGems Package Scraper - Gem Metadata & Downloads

Scrapes RubyGems.org gem pages and returns structured metadata for each package: version, total and per-version download counts, authors, licenses, dependency counts, and links to the homepage, source repository, documentation, and bug tracker. Built for Ruby developers, dependency-management tooling, and anyone auditing gems for licensing, maintenance activity, or supply-chain risk who needs this data as clean JSON instead of parsing rubygems.org by hand.

Why this scraper

• Priced at the lowest per-result rate on the store ($0.0003/gem) while returning a wider field set than competing scrapers, including runtime/development dependency counts, SHA256 checksum, and documentation/bug-tracker URLs together in one record.
• Reads the same public data RubyGems.org itself serves — no login, no API key, no rate-limit workarounds needed.
• Pay only for gems successfully scraped; no charge for failed lookups.

Output fields

Field	Type	Description
gemName	string	Name of the gem
version	string	Latest published version
downloadsTotal	integer	Total downloads across all versions
downloadsVersion	integer	Downloads for the current version
authors	string	Comma-separated list of authors
licenses	string	Comma-separated list of licenses
description	string	Gem summary/description text
homepageUrl	string	Homepage URL declared by the gem
sourceCodeUrl	string	Source code repository URL
documentationUrl	string	Documentation URL
bugTrackerUrl	string	Bug tracker URL
projectUrl	string	Canonical RubyGems.org project page URL
runtimeDependenciesCount	integer	Number of runtime dependencies
developmentDependenciesCount	integer	Number of development dependencies
sha256	string	SHA256 checksum of the gem package

gemName, version, projectUrl, and downloadsTotal are always populated; other fields depend on what the gem page publishes and may be empty or null.

Pricing

Pay-per-event: $0.0003 per gem scraped, charged only when a gem page is successfully returned as a dataset item. A run of 1,000 gems costs $0.30.

Use cases

• Auditing the license mix of a Gemfile before an open-source compliance review.
• Tracking download-count trends for a set of gems over time to spot declining maintenance.
• Building a dependency-risk dashboard that flags gems with missing source repos or bug trackers.
