Why are some WordPress links Oneboxed, and others are not?

Has anyone solved this? @AdamCapriola is there a way you can think of to make oneboxing work properly for Namati news/blog posts that just have URLs like the following:

https://domain.com/news/category-name/a-short-title
https://domain.com/resource/resource-title
https://domain.com/stories/category-name/a-short-title

If so perhaps we can contribute back the code here for the benefit of other wordpress people who don’t want to use the domain.com/year/month/day/title url syntax.
