The Rates section provides methods for obtaining actual exchange rates on the Quickex platform. A rate is understood as the ratio of one currency to another within a certain trading pair (for example, BTC → USDT).

This data allows you to build exchange calculators, display actual quotes to the user, and determine how much of the target currency you will receive when exchanging. In this section, a method is available for obtaining one specific rate in JSON format.
