     7  The oracle contains information about price quotations of crypto assets from [CoinMarketCap](https://coinmarketcap.com/). You can access quotations for the top 50 assets ranked by market capitalization.  
     8  You can execute an oracle call as follows:
     9  
    10  1.  Access DIA's [CoinMarketCap Oracle](../deployed-contracts.md).
    11  2. Call `getValue(key)` where `key` is the symbol for the asset in capital letters, for instance `BTC` for Bitcoin. You can use the "Read" section on Etherscan to execute this call.
    12  3. The response of the call contains two values:
    13     1. The current asset price in USD with a fix-comma notation of five decimals.
    14     2. The [UNIX timestamp](https://www.unixtimestamp.com/) of the last oracle update.
