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/api-endpoints#asset-markets) 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/api-endpoints#asset-quotation) provides the asset quotation for each asset in the feed.

**Oracle**

The oracle is deployed and can be accessed here.

You can query for assets by calling the read function getValue() with parameters such as “CKB/USD”. It will return two values:

1. The price of the asset queried with 8 decimals
2. 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.

Also make sure they always have sufficient funding.
