Thanks for submitting your Custom Delivery Request!

The DIA DAO will review your requirements shortly and if all information is correctly provided, a core developer will proceed and deliver the API endpoint. If the requirements are partially or incorrectly requested, a DAO member will get in touch with you again.

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.

- Goerli: [DIANFTOracle | Address 0x177a3acca28c66b85853294cc0ed767135c205e3 | Etherscan](https://goerli.etherscan.io/address/0x177a3acca28c66b85853294cc0ed767135c205e3)
- Rinkeby: [DIANFTOracle | Address 0xea1d3bcd189ef0986d04acaae495a53da731534a | Etherscan](https://rinkeby.etherscan.io/address/0xea1d3bcd189ef0986d04acaae495a53da731534a)

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 two values in six fields:

- 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.

Goerli: 0x13Ef3387966226eC1554b52f412B074c9C3a53aF  
Rinkeby: 0x0CC7453f8e826fB61c8aa3c23f69Aaf51f920372

Also make sure they always have sufficient funding in the future.

Please be aware that Rinkeby will be shut down on October 5th.
