## 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](/docs/guides/how-to-guides/fetch-price-data/solidity#access-the-library) or the [interface](/docs/guides/how-to-guides/fetch-price-data/solidity#using-the-diaoraclev2-interface).

Below is an example of a contract consuming data from our oracle on Units Network. If you pass `WBTC/USD` as the key, it will return the most recent price of WBTC in USD with 8 decimal places (e.g.11796077504693 is \$117,960.77504693) along with the Unix timestamp of the last price update.

```solidity theme={"system"}

pragma solidity ^0.8.13;

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

contract DIAOracleV2Consumer{

    address immutable ORACLE = 0xc9783a5BaBE78D979B7EB5AD43Ea3B57Acb17034;

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