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 provides the markets used for calculating this feed.

API endpoint

By querying for blockchain and asset, the API provides the Floor Price MA for each collection in the feed.

Oracle

The oracle is deployed and can be accessed here.

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.
