+Error class representing a missing expired token error from the API.
+This error occurs when the server requires an expired token to mint a new session token.
+
+Use the static `is` method to check if a ClerkAPIResponseError matches this error type.
+
+## Example
+
+```typescript
+if (MissingExpiredTokenError.is(error)) {
+  // Handle the missing expired token error
+}
+```
+
+## is()
+
+Type guard to check if an error is a MissingExpiredTokenError.
+This checks the error's properties (status and error code) rather than instanceof,
+allowing it to work with ClerkAPIResponseError instances thrown from the API layer.
+
+### Parameters
+
+| Parameter | Type      |
+| --------- | --------- |
+| `err`     | `unknown` |
+
+### Returns
+
+`err is ClerkAPIResponseError`
+
+### Example
+
+```typescript
+try {
+  await someApiCall();
+} catch (e) {
+  if (MissingExpiredTokenError.is(e)) {
+    // e is typed as ClerkAPIResponseError with the specific error properties
+  }
+}
+```
