Get datatoken information

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

{% hint style="info" %} Copy the query in the GraphiQL interface to fetch the results from the mainnet. For other networks use this table. {% endhint %}
