Discover the World of datatokens: Retrieving a List of datatokens

Get datatokens

With your newfound knowledge of fetching data NFTs and retrieving the associated information, fetching a list of datatokens will be a breeze 🌊. Building upon your understanding, let's now delve into the process of retrieving a list of datatokens. By applying similar techniques and leveraging the power of GraphQL queries, you'll be able to effortlessly navigate the landscape of datatokens and access the wealth of information they hold. So, let's dive right in and unlock the potential of exploring datatokens with ease and efficiency.

PS: In this example, the query is executed on the Ocean subgraph deployed on the mainnet. If you want to change the network, please refer to this table.

{% tabs %} {% tab title="Javascript" %} The javascript below can be used to run the query. If you wish to change the network, replace the variable's value network as needed.

var axios = require('axios');

const query = `{
    tokens(skip:0, first: 2, subgraphError: deny){
      id
      symbol
      nft {
        name
        symbol
        address
      }
      name
      symbol
      cap
      isDatatoken
      holderCount
      orderCount
      orders(skip:0,first:1){
        amount
        serviceIndex
        payer {
          id
        }
        consumer{
          id
        }
        estimatedUSDValue
        lastPriceToken
        lastPriceValue
      }
    }
}`

const network = "mainnet"
var config = {
    method: 'post',
    url: `https://v4.subgraph.${network}.oceanprotocol.com/subgraphs/name/oceanprotocol/ocean-subgraph`,
    headers: { "Content-Type": "application/json" },
    data: JSON.stringify({ "query": query })
};

axios(config)
    .then(function (response) {
        let result = JSON.stringify(response.data)
        console.log(result);
    })
    .catch(function (error) {
        console.log(error);
    });

{% tab title="Python" %} The Python script below can be used to run the query and fetch a list of datatokens. If you wish to change the network, then replace the value of the variable base_url as needed.
