Instagram Post & Reel Stats + Campaign Report

Paste a list of Instagram post and reel links. Get back likes, comments, author, posting date and the full caption for each — plus the author's follower count, an engagement rate, and a campaign report you can send straight to a client.

No login, no Instagram account, no cookies.

What it's for

• Influencer campaign reporting — you paid 20 creators to post; paste their 20 links and get total likes, comments, engagement and cost per interaction in one run.
• Creator vetting — compare engagement rates across creators before you book them.
• Competitor content tracking — re-run on a rival brand's posts and see which formats perform.
• Content research — export captions, hashtags and mentions of top-performing posts.

What you get for each post

Performance	Likes, comments, engagement rate (likes + comments ÷ followers)
Author	Username, display name, follower count, profile link
Content	Full caption, hashtags, mentions, post type (post or reel)
Timing	Posting date
Media	Cover image

The campaign report

Every run writes a CAMPAIGN_REPORT to the key-value store. Real output from a test run on four NASA-family posts with a $5,000 budget:

{
  "postsFound": 4,
  "totals": { "likes": 1491000, "comments": 7620, "interactions": 1498620, "followersReached": 109736000 },
  "engagementRate": 0.0137,
  "countsApproximate": true,
  "budget": {
    "total": 5000,
    "currency": "USD",
    "costPerPost": 1250,
    "costPerInteraction": 0.003336,
    "costPerThousandFollowersReached": 0.04556
  },
  "failed": [
    { "input": "https://www.instagram.com/p/ZZzz9nonexist1/", "error": "Instagram post not found - deleted, private, or a mistyped link" }
  ]
}

It also lists the top posts by likes and by engagement rate, and a per-creator breakdown.

Read this first: what Instagram shows logged-out visitors

Figure	What you get
Likes	Exact below 10,000; rounded above it (234K, 1M) — flagged by likesExact
Comments	Exact below 10,000; rounded above it — flagged by commentsExact
Reel views	Not available. Instagram does not publish them without a login.
Follower counts	Exact below 10,000; rounded above it

Because views are not public, engagement here is measured against followers, the standard metric agencies use for Instagram. When any post in a run has rounded counts, the report sets countsApproximate: true.

Input

{
  "postUrls": [
    "https://www.instagram.com/p/DeAYvsnn4la/",
    "https://www.instagram.com/reel/DeCPVhERA8e/"
  ],
  "campaignBudget": 5000,
  "currency": "USD"
}

Field	Default	Notes
postUrls	—	Required. Post, reel or IGTV links. Links containing the username and tracking parameters both work. Duplicates are removed.
includeAuthorFollowers	true	Look up each author once to add follower counts and engagement rate.
campaignBudget	—	Optional total spend. Adds cost per post, per interaction and per 1,000 followers reached.
currency	USD	Label for the budget.
maxConcurrency	10	Posts fetched in parallel.

Speed and cost

Measured: 36 posts from 11 accounts in 31 seconds, with no retries. The actor reads only the top ~15% of each page, where Instagram keeps the post summary, and looks up each author just once however many of their posts you include.

You only pay for posts that load

Deleted, private and mistyped links are never written to the dataset, so they are never charged. They are listed with the reason in CAMPAIGN_REPORT.failed.

Limitations

• Private accounts' posts cannot be read without logging in.
• Instagram may hide like counts on some posts; those rows have likesHidden: true and likes: null.
• Large counts are rounded by Instagram itself, so totals that include them are approximate.

Legal

Reads only what Instagram shows any visitor without logging in. You are responsible for how you use the data.
