Thank you for requesting a data feed via DIA CDR. We confirm the CDR specifications were requested correctly. Find the oracle information below:
### Oracle
The oracle is deployed and can be accessed here:
- [Polygon Amoy](https://amoy.polygonscan.com/address/0xdb702b2899ded5c5089893deb3c405074dc70b9d)
- [Polygon Mainnet](https://polygonscan.com/address/0x7bb0d1c698af19f7cfde39e938deef1f85ba175a)
You can query for assets by calling the read function getValue() with parameters such as “USDC/USD”. It will return two values:
1. The price of the asset queried with 8 decimals
2. The unix timestamp of the last update
You can see Solidity and Vyper code integration examples [here](https://docs.diadata.org/introduction/intro-to-dia-oracles/access-the-oracle#oracle-integration-example) or use a dedicated DIA oracles integration library described in detail [here](https://docs.diadata.org/introduction/intro-to-dia-oracles/access-the-oracle#accessing-dias-oracles-with-a-dedicated-solidity-library).
### Funding
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](https://docs.diadata.org/introduction/intro-to-dia-oracles/oracle-funding).
Please make sure to top up the gas wallet, as we only put in some gas to deploy and start the oracle.
Gas Wallet address:
- [Polygon Amoy: 0xb389cb7b2bdf34e61919cd4b0ea19d99242cea22](https://amoy.polygonscan.com/address/0xb389cb7b2bdf34e61919cd4b0ea19d99242cea22)
- [Polygon Mainnet: 0x0f627642711e307c7d864ec3a69fe6c6a59648fe](https://polygonscan.com/address/0x0f627642711e307c7d864ec3a69fe6c6a59648fe)
### Markets
You can view the markets included for each feed by pressing on a link to DIA App in the deployed assets list:
1. [Ethereum-0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48](https://app.diadata.org/price/asset/Ethereum/0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48/?asset=USDC)
Note: DIA uses Blockchain-Address querying formatting to ensure asset selection precision (token symbols might duplicate)
You can also query current asset prices and find other market information on the asset by using the DIA API as described [here](https://docs.diadata.org/products/token-price-feeds/access-api-endpoints).
