Freebase API: User Rate Limit Exceeded

I had a problem with my application and I exceeded the user's speed per second. This is the error I am getting.

{
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "userRateLimitExceededUnreg",
    "message": "User Rate Limit Exceeded. Please sign up",
    "extendedHelp": "https://code.google.com/apis/console"
   }
  ],
  "code": 403,
  "message": "User Rate Limit Exceeded. Please sign up"
 }
}

      

        
        
        
      

    

I have fixed my code so I will not exceed the limit anymore, but I still get the error even after 4 days. I don't really need more than the normal quota, so how can I get past that?

And what do they mean? Please register? Are they talking about requesting additional quota limits?

Is there a way to ask Freebase to track requests per second and 24 hour cycle? I am passing my API key.
