Analytics

Call GET /v1/analytics?platform=instagram (Analytics API).

Three Instagram-only endpoints go deeper:

• Account insights: account-level reach, views, accounts engaged, total interactions, follows and unfollows, profile link taps. Only reach supports metricType=time_series; Instagram serves every other metric as total_value only.
• Follower history: a daily follower count series plus followers_gained and followers_lost, served from Zernio's daily snapshots because Instagram removed follower_count from /insights in Graph API v22 and never exposed a historical daily series.
• Demographics: audience by age, city, country or gender. Requires at least 100 followers.

Media URLs. Meta's CDN links for post images and covers expire.

When one has lapsed, the analytics response re-reads the media from Meta. It serves thumbnailUrl and the mediaItems images from Zernio storage instead, so those URLs do not expire and you can cache them.

Video file URLs stay Meta's signed links and are refreshed on read once they lapse.

Stories

Two endpoints read Stories while they are live. Zernio keeps their final metrics from Meta's story_insights webhook, so they stay queryable after the 24 hours.

• List active stories: GET /v1/accounts/{accountId}/instagram/stories returns the live stories with mediaType, permalink, mediaUrl, thumbnailUrl and timestamp. Meta excludes live videos, reshared stories and copyright-flagged media, and caption, likeCount and commentsCount do not apply to stories.
• Story insights: GET /v1/accounts/{accountId}/instagram/stories/{storyId}/insights returns views, reach, replies, shares, profileVisits, follows, totalInteractions and the navigation breakdown (tapsForward, tapsBack, exits, swipesForward). source is live (fetched from Meta), cached (expired, webhook payload captured) or unavailable (expired, no payload, typical when the account connected after the story expired). Counts below 5 may come back as 0 because of Meta's privacy floor.
