There are multiple options available to query blockchain data for the peaq, krest, and agung networks. For a user-friendly experience, block explorers can be utilized. They grant access to blockchain data without the requirement of SQL or Python knowledge. For the more technically inclined users, connection to the blockchain can be established using the Substrate interface library for Python among other interfaces. Moreover, peaq has established a partnership with Subsquid, providing access to blockchain data via GraphQL APIs. This offers an alternative method for querying and retrieving data from the Krest network.
