Get list of organizations on GitHub

On June 17, 2015 GitHub added a new API to get organizations:

curl https://api.github.com/organizations

[
  {
    "login": "github",
    "id": 9919,
    "url": "https://api.github.com/orgs/github",
   "repos_url": "https://api.github.com/orgs/github/repos",
   "events_url": "https://api.github.com/orgs/github/events",
   "members_url": "https://api.github.com/orgs/github/members{/member}",
   "public_members_url": "https://api.github.com/orgs/github/public_members{/member}",
   "avatar_url": "https://avatars.githubusercontent.com/u/9919?v=3",
    "description": "GitHub, the company."
  },
  ...
]

Additional information can be found on the following link:

    "id": 1,
    "url": "https://api.github.com/orgs/github",
    "avatar_url": "https://github.com/images/error/octocat_happy.gif",
    "description": "A great organization"
  }
]

You can get a list of all accounts:

https://developer.github.com/v3/users/#get-all-users

The type parameter will tell you if it's a user or organization.

An alternative is to use the search API:

https://developer.github.com/v3/search/#search-users

You can specify type:org to get organizations only:

https://api.github.com/search/users?q=type:org

Note that it's also possible to use Github GraphQL v4 to request organization using :

{
  search(query: "type:org", type: USER, first: 100) {
    userCount
    nodes {
      ... on Organization {
        name
        createdAt
        description
      }
    }
  }
}
