A CrowdTangle alternative for public page data
If you relied on CrowdTangle for public Facebook page and Instagram account numbers, Captapi returns those as JSON: page followers and talking-about counts, posts from public groups, and Instagram follower counts. It is a per-request API, not a dashboard, so you build the tracking and the charts yourself.

Endpoints that cover this job
What Captapi does not do here
- No search across all public Facebook or Instagram content.
- No historical data from before you (or another customer) first fetched an account through Captapi.
- No dashboards, saved lists, or exports. You get JSON per request.
- Instagram post-level feeds are not covered on this page.
Frequently asked questions
Is Captapi a CrowdTangle replacement?+
For a narrow slice. You can fetch public Facebook page stats, public group posts, and Instagram profile counts as JSON. Captapi has no dashboards, no cross-platform search, and no backfilled history.
Can I track a page's followers over time?+
Yes, going forward. Facebook page and Instagram profile counts are stored each time they are fetched fresh, and GET /v1/history returns that series. History only starts when the account is first fetched.
Do I need a Facebook login or app review?+
No. You need a Captapi API key. These endpoints read public pages only.
