Getting the DHCP Pools information via API

I need to get the informations under DHCP pools to monitor the percentages of each subnet per Site Socket. However, I am having issue when pulling the "dhcpPools" and saying that permission denied error. 

Is there a query for graphql that can call this such informations in CATO?

this is my query:

query dhcpPools($accountID: ID!, $siteId: ID!, $protoId: ID!, $search: String) {

dhcpPools(

accountID: $accountID

siteId: $siteId

protoId: $protoId

search: $search

) {

dhcpPools {

...DhcpPoolData

__typename

}

__typename

}

}

fragment DhcpPoolData on DhcpPool {

subnetRange {

...EntityData

__typename

}

dhcpRange {

...EntityData

__typename

}

allocatedIPs

availableIPs

__typename

}

fragment EntityData on Entity {

id

type

name

__typename

}

this is my variable:

{

"accountID": "2015",

"siteId": "105762",

"protoId": "1000000070",

"search": ""

}
