oEmbed is a format for allowing an embedded representation of a URL on third party sites. The simple API allows a website to display embedded content (such as photos or videos) when a user posts a link to that resource, without having to parse the resource directly.

The as_article parameter triggers a non-standard oEmbed output of type article. When content is served as_article, content can be found in a body property, instead of the standard html property. Other non-standard properties, such as related_topics, are also available. This output was originally made available for one of our partners, but is available to all.
- in as_article mode, content is stripped of tags and limited to a ~256 characters excerpt (type=article, with body property).
- in standard (as_article=false) mode, content is served as markup in full, or in excerpt if provided and as set by author (type=link, with html property).
- supports posts and pages as link/html or article/body (see as_article argument).
