Thank you for requesting a DIA CDR. We confirm the CDR specifications were requested correctly. Find the oracle / API endpoint below:

**Markets**

By querying for blockchain and asset, the [API](https://docs.diadata.org/documentation/api-1/nft-data-api-endpoints) provides the markets used for calculating this feed.

**API endpoint**

By querying for blockchain and asset, the [API](https://docs.diadata.org/documentation/api-1/nft-data-api-endpoints) provides the Floor Price MA for each collection in the feed.

**Oracle**

The oracle is deployed and can be accessed here.

> **[DIANFTOracle | Address 0x0569e55031f35e24E5cD73017B17e5f29AFC2790 | Etherscan](https://goerli.etherscan.io/address/0x0569e55031f35e24E5cD73017B17e5f29AFC2790)**

> The Contract Address 0x0569e55031f35e24E5cD73017B17e5f29AFC2790 page allows users to view the source code, transactions, balances, and analytics for the contract address. Users can also interact and make transactions to the contract directly on...

You can query for collections by calling the read function getValue() with parameters such as “Ethereum-0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D”. Note that the address should be compatible with EIP-55 (i.e. case-sensitive). It will return three values in six fields:

- Field 1: The requested floor price of the collection with 8 decimals
- Field 2: The requested moving average of floor price of the collection with 8 decimals
- Field 6: The timestamp of the last update

Please make sure to top up the gas wallets very soon, as we only put in some gas to deploy and start the oracle.
