Querying a Collection

You can query the QuickNode Graph API for information about an NFT collection using the collection query. Here is an example query to retrieve information about a specific token within a specific NFT collection:

Example query

query CollectionToken($contractAddress: String!, $tokenId: String!) {
  ethereum {
    collection(contractAddress: $contractAddress) {
      name
      externalUrl
      ... on ERC721Collection {
        stats {
          volume
          floor
        }
        nft(tokenId: $tokenId) {
          tokenId
          attributes {
            name
            value
          }
          uploads {
            url
          }
        }
      }
    }
  }
}

Querying a wallet by ENS

You can query the QuickNode Graph API for information about an ENS wallet by using the walletByENS query. Here is an example in which we query a wallet by ENS to return the total count of NFTs held by the wallet, as well as details about each NFT collection within the wallet :

Example query

query NFTsByENS($ensName: String!) {
  ethereum {
    walletByENS(ensName: $ensName) {
      walletCollections {
        totalCount
        edges {
          node {
            collection {
              name
              address
              image {
                url
              }
            }
            nftsCount
          }
        }
      }
    }
  }
}

Querying Transactions

You can query the QuickNode Graph API for a paginated list of transactions by using the Transactions query. Here is an example in which we query Transactions to return details about transactions. You can filter Transactions by fromAddress, toAddress, blockNumber, and timestamp :

Example query

query walletTransactions($filter: TransactionsFilterInput){
  ethereum {
    transactions(
      first: 5
      orderDirection: DESC
      filter: $filter
    ) {
      edges {
        node {
          blockTimestamp
          fromAddress
          transactionIndex
          hash
          blockNumber
          contractAddress
          cumulativeGasUsed
          effectiveGasPrice
          gas
          gasUsed
          gasPrice
          input
          maxFeePerGas
          maxPriorityFeePerGas
          toAddress
          type
          value
        }
      }
    }
  }
}
