+## Retrieving Data
+`GET /code/<6-digit code>`  
+After the user receives the code, you should send a request to the API endpoint, which will return data about the Minecraft account.  
+The code is valid only once and for 5 minutes (by default) after it is received. After this time, the code is deleted.
+
+**Example of a Successful Response:**
+```json
