  **Free** - does not consume credits

<Info>
  This endpoint uses a two-tier system. If a cached style exists and is less than 7 days old, it returns cached data for free. If no cache exists or the cache is older than 7 days, it auto-refreshes from X (subscription required, consumes usage).

<Info>
  If a cached style already exists for this username, it will be replaced with fresh data.

<Note>
  **Next steps:** [List Styles](/api-reference/styles/list) to see all cached styles, [Get Style](/api-reference/styles/get) to retrieve a specific style, or [Analyze Performance](/api-reference/styles/performance) to fetch engagement metrics for cached tweets.
