It's my understanding that to create a personal repository on the command line, using the GitHub v3 API, one can do this (replacing USERNAME and REPONAME appropriately):
curl -u 'USERNAME' https://api.github.com/user/repos -d '{"name":"REPONAME"}'
The user then enters their username and password, and GitHub will create a new empty repository at "github.com/USERNAME/REPONAME".
My question is, how do I create an organization-owned repository via command line? I tried replacing USERNAME with the organization's name, and it prompted me for the 'host password'. I own the organization so I entered my password but I got "Bad credentials". Does this method not work for organization-owned repositories? Or am I doing something wrong?
To create a repository under an organisation you should send the request to the POST /orgs/:org/repos endpoint rather than /user/repos. Your user shouldn't need any extra permissions or scopes over what is required to create a user repository, but the user must be a member of :org:
Create

POST /user/reposCreate a new repository in this organization. The authenticated user must be a member of the specified organization.
