# Cost Minting a TimeBox incurs a fee, as storing data on the blockchain involves certain costs. The fee you need to pay is directly proportional to the weight (data size) of the TimeBox. The more files you store, the higher the fee. Currently, we only support payments with Time tokens. (During the public beta phase, you can only claim $Time through our free claim page). How is it calculated? > Fee (X = Data Size in KB) = MAX(X, 200KB) / 1024 \* 1 $TIME \* K X represents the data size in KB. If the data you put into the TimeBox is less than 200KB, it will be calculated as 200KB. K is a market coefficient, adjusted periodically based on actual storage costs, TIME TOKEN prices, and other factors. At the bottom of the Create TimeBox page, you will see an estimated cost, but the final fee is based on your actual payment. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://timebox.gitbook.io/docs/how-to-use-timebox/cost.md?ask= ``` The question should be specific, self-contained, and written in natural language.
