How much is the WC007 fee schedule?

Excuse me, could you kindly elaborate on the WC007 fee schedule? I'm particularly interested in understanding the specifics of the charges involved, such as whether they vary depending on the transaction size or type. Additionally, are there any hidden fees or extra charges that I should be aware of? Furthermore, is there a way to estimate the total cost of using the WC007 service before initiating a transaction? Your clarification on these points would be greatly appreciated.
