Turn social graph data into retention
Follower count is the vanity metric. The **business** metric is who engages, who follows whom, and how that changes week over week. Zenndra exposes graph endpoints without headless browsers.
What to measure
- Follower velocity on creator dashboards
- Following graph for discovery ("who else do they read?")
- Fans / clappers on hit articles for outreach lists
Architecture
Snapshot weekly into your warehouse. Join with your product's user ids if writers are also customers. Alert when growth stalls—often a content problem, not a API problem.
Endpoints
/user/{user_id}/followers/user/{user_id}/following/article/{article_id}/fans
