# GOAT Network

> dApps built on GOAT Network can leverage DIA oracles to access up-to-date asset price information.

DIA is a cross-chain, trustless oracle network delivering verifiable price feeds for GOAT Network. DIA sources raw trade data directly from primary markets and computes it onchain, ensuring complete transparency and data integrity.

## How to Access Data

### getValue Method

To consume price data, you'll need to invoke the [`getValue` method](/docs/guides/how-to-guides/fetch-price-data/solidity#solidity-library) on the oracle contract which you can access through the [DIA Oracle library](/docs/guides/how-to-guides/fetch-price-data/solidity#solidity-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 GOAT Network 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.

```solidity theme={"system"}
pragma solidity ^0.8.13;

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

contract DIAOracleV2Consumer{

    address immutable ORACLE = 0x458DAfFcB1507835AAB0C8F2722d1196E9a4fFaB;

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

See the full example [here](/docs/guides/how-to-guides/fetch-price-data/solidity).
