How to use RedStone Oracle in your dApp

A query is a description of the information you want to retrieve from RedStone Oracle. The request must include the type of data you want to retrieve, the data source, and the lifetime of the request.
RedStone Oracle will then send the request to the network of nodes and retrieve the data. The data will be transferred to your dApp and you can use it in your application.
You can use the data in your dApp to perform various tasks such as:

Updating the status of your dApp
Calling a smart contract
Displaying data to the user

An example of a query you can use to get the price of a token:

{ 
"type": "price", 
"symbol": "ETH", 
"source": "CoinMarketCap" 
}

This query will request the price of an ETH token from CoinMarketCap. The price will be returned as a JSON string.

Here is an example of how you can use RedStone Oracle data in your dApp:

function getPrice(symbol) { 
// Create a request for the price of the token 
 const request = { 
 type: "price", 
 symbol: symbol, 
 source: "CoinMarketCap" 
 }; 
// Send the request to RedStone Oracle 
 const response = await RedStoneOracle.sendRequest(request); 
// Get the price from the response 
 const price = response.data.price; 

// Return the price 
return price; 
}

This function requests a token price from RedStone Oracle and returns it.
