# Primary Domains

### Primary domains <a href="#primary-domains" id="primary-domains"></a>

This endpoint can be used to retrieve the primary domains of a list of user public keys. You may include up to 20 public keys in a comma separated list. Results are cached, and refreshed every 5 minutes. If you're integrating SNS into your dApp, we strongly recommend using primary domains since users have selected these domains specifically to represent their identities apart from other domains they may own.

{% hint style="info" %}
Primary domains used to be called favorite domains.
