With The Subscan API platform having been online for a few weeks, we also deployed an enhanced bot abuse detection system to prevent abusing the internal endpoints made for the Subscan web page.
Once the evaluated score reached a certain threshold, abusing bots might experience a browser checking page on Subscan (except the API endpoints). If you think that you are mistakenly marked, please let us know.
The abusing detection system is not deployed on *.api.subscan.io which is provided in the Subscan API documentation. Please ensure that you have followed Subscan API docs, therefore, the system will not potentially affect your apps.
