You can use the vSphere Automation REST API to inspect the contents of the already synchronized and imported depots. You can list the available base images, add-ons, and components, or retrieve some detailed information about a specific software update.

To retrieve a list of the base images available on a vCenter Server instance, use the GET https://<vcenter_ip_address_or_fqdn>/api/esx/settings/depot-content/base-images request. You receive in the response body, a list of BaseImages.Summary JSON objects for each available base image. To get more information about a single base image, use the GET https://<vcenter_ip_address_or_fqdn>/api/esx/settings/depot-content/base-images/versions/<version> request. You also get information about the components present in this base image.

To retrieve a list of all currently available add-ons in the vSphere Lifecycle Manager depot, use the GET https://<vcenter_ip_address_or_fqdn>/api/esx/settings/depot-content/add-ons request and submit some of the query parameters to filter the list of retrieved add-ons. To retrieve some detailed information about an add-on, use the GET https://<vcenter_ip_address_or_fqdn>/api/esx/settings/depot-content/add-ons/<name>/versions/<version> request and submit the name and version of the add-on.

To retrieve a list of all components currently available in the vSphere Lifecycle Manager depot, you can use the GET https://<vcenter_ip_address_or_fqdn>/api/esx/settings/depot-content/components request and submit some of the query parameters to filter the list of retrieved components. To retrieve detailed information about a component, use the GET https://<vcenter_ip_address_or_fqdn>/api/esx/settings/depot-content/components/<name>/versions/<version> request and submit the name and version of the component.
