## When to prefer this

Use this endpoint when you need a comprehensive social signal snapshot for a single crypto asset — including mindshare trends, sentiment, momentum, and an AI-generated narrative insight. Prefer this over the history endpoints when you want the current profile rather than a time series, and over news feed endpoints when you want aggregated social metrics rather than individual articles.
