# What Is Rangers Protocol Oracle

The Rangers Protocol oracle is a valuable tool developed and maintained by Rangers Protocol to mainly provide price services for various tokens, currently including BTC, ETH, MIX, and RPG. It uses multiple decentralized exchanges as the price feed data source, with the median calculation being used to obtain the token price. The oracle allows developers to obtain real-time prices of various tokens in USD through its free API to conduct various commercial activities.
