Key Features

Turn every post into a clear performance signal

Compare content, follow account growth, and report results without stitching together platform-specific analytics workflows. Metrics vary by platform.

  • Eight Core MetricsImpressions, reach, likes, comments, shares, saves, clicks, and views — normalized across platforms.
  • Post TimelinesDay-by-day performance for any post, so you can see how content compounds after publishing.
  • Account & Daily MetricsAggregate daily metrics per account or profile, with publish-date or received-date attribution.
  • Follower GrowthFollower history per account, tracked daily, readable from the dashboard or the API.
  • External Post SyncPostZen also discovers posts you published outside PostZen on supported platforms, so analytics cover your whole account.
  • Best Time to PostEngagement-based recommendations for when to schedule, per platform and account.

How it Works

From connection to insights in 3 steps

No tracking pixels, no spreadsheets — connect once and the numbers flow.

  1. 01. Connect Accounts

    Link accounts via hosted OAuth. Analytics permissions are part of the same connect flow.

  2. 02. PostZen Collects Metrics

    Metrics sync automatically from each platform's API — no polling code, no per-platform quirks.

  3. 03. Read Anywhere

    Explore charts in the dashboard, or pull the same numbers from the REST API, SDKs, and MCP server.

Why use PostZen?

Frequently asked questions

Still have questions?

What is a social media analytics API?

A social media analytics API lets you programmatically read post metrics, account metrics, and follower stats. PostZen collects them from each platform's official API and normalizes them behind one interface.

Which metrics does PostZen track?

PostZen tracks eight core metrics — impressions, reach, likes, comments, shares, saves, clicks, and views — plus follower counts. Which metrics a platform reports varies; metrics a platform does not expose are shown as not reported rather than zero.

Does analytics cover posts I published outside PostZen?

Yes, on supported platforms. PostZen discovers external posts on your connected accounts and includes them in analytics.

How far back can I query?

Post analytics queries default to the last 90 days per request, and daily metrics support up to 180 days per request. Use fromDate and toDate to pick the window.

Can I build my own dashboard on top of it?

Yes. PostZen provides consistent REST endpoints for post analytics, timelines, daily metrics, best-time recommendations, and follower stats, plus SDKs.

Can AI agents read analytics?

Yes. The hosted MCP server exposes analytics tools — getAnalytics, getPostTimeline, getDailyMetrics, getFollowerStats, and getBestTimeToPost — so agents can report on performance.
