# DIA

## Overview

DIA is a cross-chain oracle platform for Web3. It serves as an ecosystem for transparent financial data within a smart contract environment dedicated to finance. DIA's mission is to foster a collaborative environment among data analysts, providers, and consumers. Essentially, DIA offers a trustworthy and verifiable conduit linking external data from diverse origins to on-chain smart contracts, facilitating the creation of a myriad of financial decentralized applications. DIA is architected as a hybrid framework, integrating off-chain mechanisms for the storage and manipulation of extensive datasets, with on-chain elements that supply data to financial smart contracts.

### DIA's API 

Display the most transparent data to your users using DIA's API. Whether you're developing a financial service, a portfolio management tool, a new media platform, or anything else, DIA provides the most advanced and up-to-date data for your product. 

### API Access 

The base URL for DIA is <https://api.diadata.org/v1>. All API paths are extensions of this base URL. Detailed documentation for our API endpoints can be found on the [API documentation site](https://docs.diadata.org/documentation/api-1/api-endpoints).

### DIA's Oracle

Here is an overview of the deployed oracle contracts on each supported chain.&#x20;

DIA Development Oracle contracts are smart contracts that offer a selected range of asset prices for live testing on our Mainnet and Testnet. These contracts are regularly updated and replaced, not maintained indefinitely.&#x20;

DIA Development Oracle contracts are not meant to be integrated into a dApp. DIA creates specific contracts for dApps. To request a dedicated oracle, please contact the team on their website[ Discord ](https://discord.gg/bHKuz3bzaA)or the [DIA DAO Forum](https://dao.diadata.org/).

### Example (Solidity)

```solidity
pragma solidity ^0.8.13;

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

contract IntegrationSample{

    address immutable ORACLE = 0x719108DC653CC3a9055ab8d9018c5D7924912631;
    uint128 public latestPrice; 
    uint128 public timestampOflatestPrice; 
   
    function getPriceInfo(string memory key) external {
        (latestPrice, timestampOflatestPrice) = IDIAOracleV2(ORACLE).getValue(key); 
    }
   
    function checkPriceAge(uint128 maxTimePassed) external view returns (bool inTime){
         if((block.timestamp - timestampOflatestPrice) < maxTimePassed){
             inTime = true;
         } else {
             inTime = false;
         }
    }
}
```
