+    <code class="details" id="get">get(project, clientOperationId=None)</code>
+  <pre>Fetch the representation of an existing Project.
+
+Args:
+  project: string, Identifies the project addressed by this request. (required)
+  clientOperationId: string, For mutating operation requests only. An optional identifier specified by the client. Must be unique for operation resources in the Operations collection.
+
+Returns:
+  An object of the form:
+
+    { # A project resource. The project is a top level container for resources including Cloud DNS ManagedZones. Projects can be created only in the APIs console.
+    "quota": { # Limits associated with a Project. # Quotas assigned to this project (output only).
+      "networksPerPolicy": 42, # Maximum allowed number of networks per policy.

+      "managedZonesPerNetwork": 42, # Maximum allowed number of managed zones which can be attached to a network.
+      "totalRrdataSizePerChange": 42, # Maximum allowed size for total rrdata in one ChangesCreateRequest in bytes.
+      "resourceRecordsPerRrset": 42, # Maximum allowed number of ResourceRecords per ResourceRecordSet.
+      "targetNameServersPerManagedZone": 42, # Maximum allowed number of target name servers per managed forwarding zone.

+          "keyType": "A String", # Specifies whether this is a key signing key (KSK) or a zone signing key (ZSK). Key signing keys have the Secure Entry Point flag set and, when active, will only be used to sign resource record sets of type DNSKEY. Zone signing keys do not have the Secure Entry Point flag set and will be used to sign all other types of resource record sets.
+          "keyLength": 42, # Length of the keys in bits.
+          "kind": "dns#dnsKeySpec", # Identifies what kind of resource this is. Value: the fixed string "dns#dnsKeySpec".
+          "algorithm": "A String", # String mnemonic specifying the DNSSEC algorithm of this key.
