If an eligible staking position's status is `Unregistered`, you can initiate a registration for it. You can filter the results by registration status. You can use this operation to: - Check which staking positions can be registered - Get staking details before initiating registration - Monitor available positions for registration As registration is an asynchronous process and might take some time to complete, it is recommended that you regularly call this operation to check staking position eligibility and register eligible positions on time.
