Quota Limits on generativelanguage.googleapis.com

Gemini API
,
1

Hi,

May be this is discussed earlier but I cannot see a correct solution for my issue. I have a Tier 1 Plan and all billing are set, but when I try to use my API key following is thrown

curl "https://generativelanguage.googleapis.com/v1beta/models/gemini-pro:generateContent" \
        -H 'Content-Type: application/json' \ 
        -H "x-goog-api-key: MYKEY" \
        -X POST \ 
        -d '{  
              "contents": [ 
                {  
                  "parts": [        
                    {                
                      "text": "Hello"
                    }
                  ]
                }  
              ]  
            }'  

  {
    "error": {
      "code": 429,
      "message": "Quota exceeded for quota metric 'Generate Content API requests per minute' and limit 'GenerateContent request limit per minute for a region' of service 'generativelanguage.googleapis.com' for

          }
        },
        {
          "@type": "type.googleapis.com/google.rpc.Help",
          "links": [
            {
              "description": "Request a higher quota limit.",
              "url": "https://cloud.google.com/docs/quotas/help/request_increase"
            }
          ]
        }
      ]
    }
  }

Any suggestions how to overcome this.
