Query Scope

Scalar API queries are grouped into four scopes. Each scope allows access to a different piece of a Scalar book. A combination of calls might be needed to gain all information about a Scalar book (e.g., the book’s title and all of its content). However, a single call, for example to instancesof/content, will return all content in a Scalar book. Adding a GET variable to the same call will return all content plus all relationships between content, effectively modeling the entire Scalar book in a single query.
