Instagram data for influencer marketing platforms
Discovery, vetting and reporting all start with the same data: who a creator is, how big their audience is, what they post and how it performs. IGramAPI returns that for any public account from a username.
How it fits together
Find
Turn a name or niche keyword into candidate accounts with verification and follower counts.
Vet
Check audience size, bio, link and verification before outreach.
Analyze
Pull recent posts and reels to compute average engagement and posting cadence.
Report
See which creators rank under your campaign hashtag.
Build a creator database that stays fresh
Store each creator's numeric user id and refresh their profile on a schedule. Because follower and following counts are plain integers, you can chart growth, detect sudden spikes and rank creators without parsing text like '1.2M'.
Engagement rate needs likes, comments and followers. The posts endpoint returns the first two for every post and the profile endpoint returns the third, so a complete engagement calculation takes two calls.
No creator login required
The official API requires each creator to connect their account to your app. That is fine for managing talent you already work with, but it is impossible for discovery. IGramAPI works from public information, so you can evaluate anyone before reaching out.

Questions
Can I calculate engagement rate with the API?
Yes. Fetch recent posts for likes and comments, fetch the profile for followers, and divide. Posts where the owner hides like counts are flagged so you can exclude them.
How many creators can I check per month?
A profile lookup is 1 credit. On the Pro plan, 100,000 credits cover 100,000 lookups, or a smaller number of deeper reports that also fetch posts.
Is audience demographics data available?
No. Demographics are private to the account owner and are not exposed. The API covers public data only.
