• Path:
  • /status/
• Available methods:
  • GET
• Returned fields (back-end returns to the front-end):
  • “user_count”: total number of users
  • “answer_count”: total number of answers
  • “location_is_done_count”: the number of locations that have been labeled

There is a demand of showing the user how many cases did he or she identify. API need to be adjusted a little for this service.
