UserAgent updated to version 143

Please review the terms of use for materials on this site.

UserAgent has been updated to version 143. This is an important update for all CapMonster Cloud users, significantly affecting the improvement of CAPTCHA recognition accuracy.

The current UserAgent (UA) plays a key role in achieving maximum recognition accuracy. For the best results, ensure that each recognition request uses the latest UA string for Windows:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) 
AppleWebKit/537.36 (KHTML, like Gecko) 
Chrome/143.0.0.0 Safari/537.36

Regularly updating the UserAgent helps maintain high accuracy and reduces the likelihood of recognition errors.

You can also update the UserAgent string automatically via the API method.

Note: the product is intended solely for automating testing on your own websites or resources that you have lawful access to.
