You need the appropriate permissions to list or use public
APIs and services in a Google Cloud project. For example, to enable a service,
you need the serviceusage.services.enableIdentity and Access Management permission. To
learn about the required IAM permissions for
Service Usage, see
Access Control.
Private APIs and services
Private services are
typically APIs implemented using Cloud Endpoints running in
another Google Cloud project. To discover or use private APIs and services,
you must be first be granted access by a principal with the necessary
permissions. To learn how to grant access to enable Cloud Endpoints APIs from
a Google Cloud project, see the following pages for each of the respective
Cloud Endpoints API frameworks:
You must also have the appropriate IAM permissions to list or use
private APIs and services. For example, to call the
services.enable
method for a private service, the servicemanagement.services.bind permission
is required. To learn about the necessary permissions for
Service Usage, see Access Control.
When you list available or enabled APIs and services in a Google Cloud project
, the results include any public and private APIs you have access to. To learn
more about listing enabled and available services in your
Google Cloud projects, see
Listing Services.

Examples of public Google Cloud APIs and services include:\n\n- [BigQuery API](/bigquery)\n- [Cloud Storage](/storage)\n- [Cloud Monitoring API](/monitoring)\n\nYou need the appropriate permissions to list or use public\nAPIs and services in a Google Cloud project. For example, to enable a service,\nyou need the `serviceusage.services.enable` [Identity and Access Management](/iam) permission. To\nlearn about the required IAM permissions for\nService Usage, see\n[Access Control](/service-usage/docs/access-control).\n\nPrivate APIs and services\n-------------------------\n\nPrivate services are\ntypically APIs implemented using [Cloud Endpoints](/endpoints) running in\nanother Google Cloud project.
