Details on interacting with RubyGems.org over HTTP.

NOTE: The API is a work in progress, and can use your help! RubyGems itself and the gemcutter gem use the API to push gems, add owners, and more.

API Authorization

Some API calls require an Authorization header. To find your API key, click on your username when logged in to RubyGems.org and then click on ‘Edit Profile’. Here’s an example of using an API key:

$ curl -H 'Authorization:YOUR_API_KEY' \
  https://rubygems.org/api/v1/some_api_call.json

Ruby Library

You can also interact with RubyGems.org using Ruby.

The gems client provides a Ruby interface to all the resources listed below. This library has full documentation that includes some basic usage examples in the README. You can install the library with the command:

gem install gems

Gem Methods
