# ApexCache > Edge API caching gateway with database-aware invalidation ApexCache is an edge API caching gateway. Point a CNAME at your API subdomain, configure one upstream origin URL, and cache safe GET responses at the edge. Invalidate by key, tag, REST mutation, or automatic CDC from PostgreSQL, MySQL, and MongoDB.
