# Oracle of Delphi

*Aptos CLI Version: 2.3.1*

An implementation of a price oracle module. 

This quest features a price oracle module using the ‘push model’. The oracle admin account routinely submits prices for coin pairs and anyone can use those prices on chain.

The quest is comprised of the following functionality:

- `update_price_feed`: Let the admin account update a price for a coin pair.

        Example
        
        Input
        pair = "APT/USDC"
        price = 691000000
        confidence = 00001000
        
        Explanation: Admin submits the following price and confidence for the "APT/USDC" 
        coin pair. This will either update the existing price or initialize the price.
        The confidence means that the price is accurate within +/- .00001 APT. So there 
        would be a range of 6.91001 APT and 6.90999 APT

- `get_price`: Allows anyone to retrieve a copy of the price of a request pair to use on chain.
