UserAgent Updated to Version 139

We’d like to inform all CapMonster Cloud users about an important update designed to improve CAPTCHA recognition accuracy: the UserAgent has been updated to version 139.

Having the latest UserAgent (UA) is crucial for achieving the best possible recognition results. For maximum efficiency, please make sure every recognition request uses the newest Windows-based UA string:

Mozilla/5.0 (Windows NT 10.0; Win64; x64)   
AppleWebKit/537.36 (KHTML, like Gecko)   
Chrome/139.0.0.0   
Safari/537.36 

Regularly updating your UserAgent helps maintain accuracy and reduce recognition errors.

You can also refresh the UserAgent automatically using the API method.
