 ## About Primus Network-Core-SDK
 
-When integrating data verification solutions into your **backend** server, you can utilize the **Primus Network Core SDK**. For integrating Primus network capabilities with DApps for end users, please refer to the [DApp Integration](https://docs.primuslabs.xyz/primus-network/build-with-primus/for-developers/example) guide.

 The Network-Core-SDK allows you to verify data through API endpoint responses. An authorized token or other credential is required to request private data if the data source server requires permissioned access. Note that in the backend integration situation, the developer usually proves their off-chain data in their built application, and the Primus extension is **not** required. Typical scenarios include proof of reserves, in which a configured web page periodically proves that the stablecoin issuer holds sufficient collateral across off-chain platforms.
