+# @ohos.deviceAttest (Device Attestation)
+
+The **deviceAttest** module provides attestation of devices in OpenHarmony by comparing the device information with that stored in the cloud.
+You can use the APIs provided by the **deviceAttest** module to obtain the device attestation result.
+
+> **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
+
+```js
+import deviceAttest from '@ohos.deviceAttest';
+```
+
+## deviceAttest.getAttestStatus
+
+getAttestStatus(callback: AsyncCallback<AttestResultInfo>) : void
+
+Obtains details about the device attestation result from the cloud. This API uses an asynchronous callback to return the result.
+
+**System capability**: SystemCapability.XTS.DeviceAttest
+
+**Parameters**
+
+| Name  | Type                                                       | Mandatory| Description                                                        |
+| -------- | ----------------------------------------------------------- | ---- | ------------------------------------------------------------ |
+| callback | AsyncCallback&lt;[AttestResultInfo](#attestresultinfo)&gt; | Yes  | Callback invoked to return the result.<br/>If the operation is successful, **error** is **undefined**, and **result** is the [AttestResultInfo](#attestresultinfo) obtained. Otherwise, **error** is an error object. |
+
+**Error codes**
+
+| ID | Error Message            |
+|----------|----------------------|
+| 20000001 | system service exception. |
+
+**Example**
+
+```js
+try {
+    deviceAttest.getAttestStatus((error, value) => {
+    if (typeof error != 'undefined') {
+        console.info("error code:" + error.code + " message:" + error.message);
+    } else {
+        console.info("auth:" + value.authResult + " software:" + value.softwareResult + " ticket:" + value.ticket);
+        console.info("versionIdResult:" + value.softwareResultDetail[0],
+        " patchlevelResult:" + value.softwareResultDetail[1],
+        " roothashResult:" + value.softwareResultDetail[2],
+        " PCIDResult:" + value.softwareResultDetail[3],
+        " reserver:" + value.softwareResultDetail[4]);
+    }
+    })
+} catch (error) {
+    console.info("error code:" + error.code + " message:" + error.message);
+}
+```
+
+## deviceAttest.getAttestStatus
+
+getAttestStatus() : Promise&lt;AttestResultInfo&gt;
+
+Obtains details about the device attestation result from the cloud. This API uses a promise to return the result.
+
+**System capability**: SystemCapability.XTS.DeviceAttest
+
+**Return value**
+
+| Type                                                 | Description                           |
+| ----------------------------------------------------- | ------------------------------- |
+| Promise&lt;[AttestResultInfo](#attestresultinfo)&gt; | Promise used to return the device attestation information obtained.|
+
+**Error codes**
+
+| ID | Error Message            |
+|----------|----------------------|
+| 20000001 | system service exception. |
+
+**Example**
+
+```js
+try {
+    deviceAttest.getAttestStatus().then((value) => {
+    console.info("auth:" + value.authResult + " software:" + value.softwareResult + " ticket:" + value.ticket);
+    console.info("versionIdResult:" + value.softwareResultDetail[0],
+        " patchlevelResult:" + value.softwareResultDetail[1],
+        " roothashResult:" + value.softwareResultDetail[2],
+        " PCIDResult:" + value.softwareResultDetail[3],
+        " reserver:" + value.softwareResultDetail[4]);
+    }).catch((error) => {
+    console.info("error code:" + error.code + " message:" + error.message);
+    });
+} catch (error) {
+    console.info("error code:" + error.code + " message:" + error.message);
+}
+```
+
+## deviceAttest.getAttestStatusSync
+
+getAttestStatusSync() : AttestResultInfo
