+# @ohos.systemCapability (SystemCapability)
+
+System capability (SysCap) refers to a relatively independent feature in the operating system. Different devices provide different system capabilities, and multiple APIs implement a system capability. You can determine whether an API can be used based on system capabilities. This module provides APIs for querying the set of system capabilities.
+
+> **NOTE**
+>
+> - The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+> - The APIs provided by this module are system APIs.
+
+
+## Modules to Import
+
+```ts
+import systemcapability from '@ohos.systemCapability'
+```
+
+## systemcapability.querySystemCapabilities
+
+querySystemCapabilities(callback: AsyncCallback<string>): void;
+
+Queries system capabilities. This API uses an asynchronous callback to return the result.
+
+**System capability**: SystemCapability.Developtools.Syscap
+
+**Parameters**
+
+| Name| Type| Mandatory| Description|
+| -------- | -------- | -------- | -------- |
+| callback | AsyncCallback<string> | Yes| Callback invoked to return the result.|
+
+
+**Example**
+
+```ts
+try {
+    systemcapability.querySystemCapabilities(function (err, data) {
+    if (err == undefined) {
+        console.log("get system capabilities:" + data)
+    } else {
+        console.log(" get system capabilities err:" + err.code)
+    }});
+}catch(e){
+    console.log("get unexpected error: " + e);
+}
+```
+
+
+## systemcapability.querySystemCapabilities
+
+querySystemCapabilities(): Promise&lt;string&gt;
+
+Queries system capabilities. This API uses a promise to return the result.
+
+**System capability**: SystemCapability.Startup.SystemInfo
+
+**Return value**
+
+| Type| Description|
+| -------- | -------- |
+| Promise&lt;string&gt; | Promise used to return the result.|
+
+**Example**
+
+```ts
+try {
+    var p = systemcapability.querySystemCapabilities();
+    p.then(function (value) {
+        console.log("get system capabilities: " + value);
+    }).catch(function (err) {
+        console.log("get system capabilities error: " + err.code);
+    });
+}catch(e){
+    console.log("get unexpected error: " + e);
+}
+```
+
+
+> **NOTE**
+> - The system capabilities returned by the preceding APIs are in the form of an encoded numeric string.
