Explore the Power of Querying: Unveiling In-Depth Details of Individual Datatokens

Get datatoken information

To fetch detailed information about a specific datatoken, you can utilize the power of GraphQL queries. By constructing a query tailored to your needs, you can access key parameters such as the datatoken's ID, name, symbol, total supply, creator, and associated dataTokenAddress. This allows you to gain a deeper understanding of the datatoken's characteristics and properties. With this information at your disposal, you can make informed decisions, analyze market trends, and explore the vast potential of datatokens within the Ocean ecosystem. Harness the capabilities of GraphQL and unlock a wealth of datatoken insights.

The result of the following GraphQL query returns the information about a particular datatoken. Here, 0x122d10d543bc600967b4db0f45f80cb1ddee43eb is the address of the datatoken.

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 and fetch the information of a datatoken. If you wish to change the network, replace the variable's value network as needed. Change the value of the variable datatokenAddress with the address of your choice.
