# Getting Information About My Organization

The examples in this section use REST API resources to retrieve organization-level information, such as a list of all objects available in your organization.

- **[List Available REST API Versions](/docs/platform/api-rest/guide/dome-versions.md)**

  Use the Versions resource to list summary information about each REST API version currently available, including the version, label, and a link to each version's root. You don’t need authentication to retrieve the list of versions.

- **[List Org Limits](/docs/platform/api-rest/guide/dome-limits.md)**

  Use the Limits resource to list your org limits.

- **[List Available REST Resources](/docs/platform/api-rest/guide/dome-discoveryresource.md)**

  Use the Resources by Version resource to list the resources available for the specified API version. This provides the name and URI of each additional resource.

- **[Get a List of Objects](/docs/platform/api-rest/guide/dome-describeglobal.md)**

  Use the Describe Global resource to list the objects available in your org and available to the logged-in user. This resource also returns the org encoding, as well as maximum batch size permitted in queries.

- **[Get a List of Objects If Metadata Has Changed](/docs/platform/api-rest/guide/describe-global-with-ifmodified-header.md)**

  Use the Describe Global resource and the `If-Modified-Since` HTTP header to determine if an object’s metadata has changed.
