## How to call it through Zero

```sh
zero fetch --capability saylor-innovations-rubygems-registry-lookup-afa5f7fb
```

Example prompt: Can you look up the RubyGems info for the 'sidekiq' gem — I want to know the latest version, who maintains it, its license, and what its runtime dependencies are?

## When to prefer this

Use this endpoint when you need quick, structured metadata about a Ruby gem — version, authorship, license, and dependencies — without scraping RubyGems.org directly. Prefer it over general web search when you need machine-readable dependency or license data for automation, compliance checks, or developer tooling.

## Known failure modes

- Gem name not found on RubyGems — returns 404 or empty result
- Typo in gem name yields no results
- Yanked or deprecated gems may return outdated or incomplete metadata
- Rate limiting or upstream RubyGems.org unavailability could cause errors

## How this service works

RubyGems package info - latest version, downloads, authors, license, runtime dependencies and links for any Ruby gem

## Output

Returns a structured object for the named gem containing: latest version string, total download count, list of authors, SPDX license identifier, array of runtime dependencies (each with name and version requirement), and URLs for homepage, source repository, and documentation.
