Octocoder is a simple rack-based web service for use by Coderwall to identify users' repository-based achievements. E.g.

  • Riding the Rails - user has contributed to the Rails framework.
  • In the Wee Small Hours - user has contributed to the Sinatra framework.


In a nutshell, you'll query and get the JSON response {"count":6} indicating that leereilly has made 6 contributions to the repository called rails owned by user rails.

Note About API Version

If you want to always use the latest API version, point to

NB: This is usually considered bad practice i.e. if the API changes then your app might crash/burn/kill.

If you want to always hit version 2 of the API (current stable version) hit


Contributions are welcome and encouraged! You know the drill.

  • Fork.
  • Commit code with tests.
  • Pull.

General guidelines

Any changes to the actual API that aren't backwards-compatible should be added to a new version.


  • GitHub for being awesome and having a public API
  • Coderwall
  • Gems sinatra, mongo-mapper, shotgun, heroku, rest-client, json, rspec, rack-test and webrat

Bugs / Known Issues

  • This is hosted on a free Heroku account with only one dyno i.e. performance and availability not guaranteed.
  • The current GitHub API (Version 3) document doesn't list Contributor as an available resource; it may be modified/removed at any time :-o
  • More in the issues ^
  • The first time a repository is hit, all the contributors are cached. Subsequent calls will be faster.
