Am I billed for user queries that return 404 errors?

You are not billed for user queries that return 404 errors. For example, if a malicious user is sending requests to an invalid/undefined index on your application, this does not impact your usage. 

Erroneous responses return nbQueries = 0 , so the total usage on your application is not increased and you will not be billed for these requests.
