When purchasing Keys via the CLI, you may use the estimate-node-purchase-price command to view the total cost (in Arb ETH) of purchasing a specified number of Keys.
The price of Xai Sentry Keys increase in tranches per this table. If your purchase crosses a tranche, the estimate-node-purchase-price command will account for the higher unit price of Keys in its calculation.
Here's how to use this function to retrieve the estimated cost of purchasing a specified number of Keys (not including gas):
Type in the command estimate-node-purchase-price into the CLI.
Enter the quantity of Keys you would like to purchase.
Hit 'Enter'.
View the result for "Estimated Total Price".
