# Data Client

Once a user has authenticated their wallet on your website, you will get access to an instance of the data client, which contains a set of rich API's that allow your website to quickly and easily retrieve NFT information and access other Manifold Services.

*Note that the Data Client is ONLY accessible if the following conditions are met:*

* You have installed the Connect Widget on your website
* The user has [authenticated their wallet](/manifold-for-developers/resources/widgets/connect-widget/wallet-authentication.md)

You can get an instance of the data client via the `m-authenticated` [event](/manifold-for-developers/resources/widgets/connect-widget/wallet-authentication.md) or `window.manifold` [window object](/manifold-for-developers/resources/widgets/connect-widget/wallet-authentication.md).
