You can query for assets by calling the read function getValue() with parameters such as “KLIMA/USD”. It will return two values:
The price of the asset queried with 8 decimals
The unix timestamp of the last update
You can see Solidity and Vyper code integration examples here or use a dedicated DIA oracles integration library described in detail here.

Each deployed oracle contract has a separate gas wallet which is the only entity allowed to update oracle values based on selected parameters. To find out more information on how it works, visit the following link.
Please make sure to top up the gas wallet, as we only put in some gas to deploy and start the oracle.
