How to Access Data

​
getValue Method

To consume price data, you’ll need to invoke the getValue method on the oracle contract which you can access through the DIA Oracle library or the interface. Below is an example of a contract consuming data from our oracle on Aurora mainnet. If you pass BTC/USD as the key, it will return the most recent price of BTC in USD with 8 decimal places (e.g. 9601458065403 is $96,014.58065403) along with the Unix timestamp of the last price update. 
pragma solidity ^0.8.13;

interface IDIAOracleV2 {
    function getValue(string memory) external view returns (uint128, uint128);
}

contract DIAOracleV2Consumer{

    address immutable ORACLE = 0xf4e9C0697c6B35fbDe5a17DB93196Afd7aDFe84f;

    function getPrice(string memory key)
    external
    view
    returns (
        uint128 latestPrice,
        uint128 timestampOflatestPrice
    ) {
        (latestPrice, timestampOflatestPrice) =
                 IDIAOracleV2(ORACLE).getValue(key);
    }
}
