 If you are interested in learning how app fees work, and how you can add them to your quotes please check out our [App Fees Doc](/features/app-fees).
 
+To check how a token is classified programmatically, use [`GET /currencies/classifications`](/references/api/get-currency-classifications), which returns the current stable and major symbol lists; any token in neither list is treated as minor.

 _Please note that the above fee structure applies to standard cases. In certain cases, such as route-specific campaigns or promotions, different fees may apply._

+<Note>
+The response lists the token symbols (lowercase) currently classified as **stable** and **major** — the live source of the fee-category lists in [Fees](/references/api/api_core_concepts/fees). There is no `minor` list: any token in neither array is treated as minor for fees. Classification is by symbol, not by contract address, and the lists can change as Relay adds tokens.
