Query not fetching details of all the coins

At the time of creating this topic there are 8612 tokens in BSC network. I am using below query to get the token count.

{
  ethereum(network: bsc) {
    smartContractCalls(
      smartContractMethod: {is: "Contract Creation"}
      smartContractType: {is: Token}
    ) {
      count
    }
  }
}

{
  "ethereum": {
    "smartContractCalls": [
      {
        "count": 8612
      }
    ]
  }
}

When I am trying to extract details of all these 8612 tokens using the below query I am getting details of only 1632. Below is the query I am using to fetch the token details.

{

 ethereum (network: bsc) {

   smartContractCalls(options: {desc: "block.height", limit:9000}, 

     smartContractMethod: {is: "Contract Creation"}, 

     smartContractType: {is: Token}) {

     block {

       height

       timestamp {

         time

       }

     }

     smartContract {

       contractType

       address {

         address

         annotation

       }

       currency {

         name

         symbol

         decimals

         tokenType

       }

     }

   }

 }

}

I am using python program. Below is my python program. Could you please take a look into this and suggest why I am not getting details of all the tokens and getting only a subset of it?

                            json={'query': query}, headers=headers)

    print('[+] Getting details from BSCSCAN. Please wait.')                            

    if request.status_code == 200:

        return request.json()
