API Access Token for api(dot)freecodecamp(dot)org/api

I’ve found that using api(dot)freecodecamp(dot)org/api can get the public details of that particular user.
I have 100-150 students, that I can guide them to follow FCC, As the teacher it seems like I use this free API endpoint for my usage to track those students progress into a custom dashboard. But I’ve following confusions, please can someone clarify on that.

1.) Will my server get block if 100-150 API calls happens in a day, in order to update the dashboard.
2.) And does anyone know to obtain a valid API Access Token for this API. I can provide my certified information of the institute and my program proposal to that also.
