# Reference

This is a full list of the available CSPR.cloud REST API entities. Some of the entities are presented as root-level resources, and some represent related information of the root-level resources and are presented as their edges. The endpoints associated with each entity provide all the relevant data about that entity. Value objects that provide a mapping between identifiers and names aren't listed here and are documented with the corresponding endpoint documentation.

Entities may have relations to other entities. Such relations are exposed by the presence of one entity identifier in the other entity properties. Typically, it means that this identifier can be used as a [query filter](https://docs.cspr.cloud/1.3.x/documentation/overview/filtering) in the API requests and that the related entity could be included in the responses as an [optional property](https://docs.cspr.cloud/1.3.x/documentation/overview/optional-properties).
