# RubyGems Metadata Scraper (`klondikeking/rubygems-scraper`) Actor - **URL**: https://apify.com/klondikeking/rubygems-scraper.md - **Developed by:** [Pierrick McD0nald](https://apify.com/klondikeking) (community) - **Categories:** Developer tools - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing Pay per usage This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## RubyGems Metadata Scraper — Extract Package Data from RubyGems.org The RubyGems Metadata Scraper extracts comprehensive package information from RubyGems.org, the official Ruby package registry. This Actor retrieves version details, download statistics, dependency trees, authorship, licensing, and source code links for any Ruby gem — ideal for dependency analysis, security auditing, market research, and compliance reporting. ### Use Cases - **Dependency Analysis** — Map out full dependency trees for Ruby projects to identify transitive dependencies and version constraints. - **Security Auditing** — Track gem versions and checksums (SHA) to verify package integrity and detect outdated or vulnerable dependencies. - **Market Research** — Analyze download trends and author ecosystems to identify popular gems and emerging libraries. - **License Compliance** — Extract license information from gems to ensure compliance with open-source policies. - **Portfolio Tracking** — Monitor version updates and download growth for gems your organization depends on. ### Input | Field | Type | Required | Description | |-------|------|----------|-------------| | `gemNames` | Array | Yes | List of Ruby gem names to scrape (e.g., rails, sinatra, devise) | | `maxItems` | Number | No | Maximum gems to process (default: 100) | | `proxyConfiguration` | Object | No | Proxy settings (optional) | ### Output The Actor outputs a dataset with the following fields for each gem: ```json { "name": "rails", "version": "8.1.3", "downloads": 735455152, "versionDownloads": 2112129, "authors": "David Heinemeier Hansson", "info": "Ruby on Rails is a full-stack web framework...", "licenses": ["MIT"], "homepageUri": "https://rubyonrails.org", "sourceCodeUri": "https://github.com/rails/rails/tree/v8.1.3", "bugTrackerUri": "https://github.com/rails/rails/issues", "documentationUri": "https://api.rubyonrails.org/v8.1.3/", "dependencies": ["actioncable (= 8.1.3)", "actionmailbox (= 8.1.3)", ...], "platform": "ruby", "sha": "6d017ba5348c98fc909753a8169b21d44de14d2a...", "projectUri": "https://rubygems.org/gems/rails", "gemUri": "https://rubygems.org/gems/rails-8.1.3.gem", "scrapedAt": "2026-04-23T16:00:00.000Z" } ```` ### Pricing Pay per event: $0.001 per gem scraped. No minimum fees. Proxy usage is optional — the RubyGems API is publicly accessible and does not require proxy rotation for typical usage. ### Limitations - Only publicly available gems on RubyGems.org can be scraped. - Gems that have been yanked or removed may return errors. - Rate limiting may apply for very large batches — the Actor includes automatic retry logic. - Dependency information includes only runtime and development dependencies as declared by the gem author. ### FAQ **Q: Do I need a proxy?** A: No. The RubyGems API is publicly accessible and typically does not block datacenter IPs. Proxy configuration is available as an optional setting. **Q: Can I scrape private gems?** A: No. This Actor only accesses publicly published gems on RubyGems.org. **Q: What happens if a gem name does not exist?** A: The Actor logs the error and continues processing the remaining gems. Failed lookups are recorded in the run statistics. ### Changelog - **v1.0.0** — Initial release with full metadata extraction, dependency parsing, and PPE charging. # Actor input Schema ## `gemNames` (type: `array`): List of Ruby gem names to scrape (e.g., rails, sinatra, devise) ## `maxItems` (type: `integer`): Maximum number of gems to process ## `proxyConfiguration` (type: `object`): Proxy settings (optional - RubyGems API usually works without proxy) ## Actor input object example ```json { "gemNames": [ "rails", "sinatra", "devise" ], "maxItems": 100, "proxyConfiguration": { "useApifyProxy": true } } ``` # Actor output Schema ## `results` (type: `string`): Extracted gem metadata ## `stats` (type: `string`): Execution statistics # API You can run this Actor programmatically using our API.
