### Key Features

* Complete verifiability from source to destination smart contract.
* Direct data sourcing from 100+ primary markets eliminating intermediary risk.
* Support for 20,000+ assets across all major asset classes.
* Custom oracle configuration with tailored sources and methodologies.

## How to Access Data

### getValue Method

Call the `getValue()` function on the oracle contract with the Query Symbol (e.g., "BTC/USD"). The function returns the asset price with 8 decimal precision and the timestamp of the last update.

#### Solidity Example

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

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

contract DIAOracleV2Consumer {
    // E.g. Boba Sepolia Oracle Address: 0x907e7f6bd9653e4188da89e4f2d3ea949dcec076
    address immutable ORACLE = 0x907e7f6bd9653e4188da89e4f2d3ea949dcec076;

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