There are two ways to get an article via the ScribbleLive API:
By article ID
/article/{Article Id}?Token={API Token}
By event ID (each article is associated with an event)
/article/post/{Post Id}?Token={API Token}
Those calls will return the HTML content of the article and information about the article.
Once you have the article on the page, check for updates with this call:
/article/{Article Id}/revision/published/latest?Token={API Token}
