Instagram Post Engagers Lead List

Instagram

Operated by Sourcelane✓ verified

A tool that turns Instagram post engagers (commenters and likers) into a de-duplicated, ranked lead list by aggregating engagement across posts or a profile's recent posts. It identifies unique people who interacted with specified Instagram content, computes an engagement score that weights comments higher than likes, and ranks results so the most engaged users appear first. For each person it returns profile identifiers and status, engagement metrics (counts, number of posts engaged, weighted score), timestamps and examples of their comments, lists of engaged post URLs and per-engagement records (type, text, timestamp, like counts), and — when profile enrichment is enabled — public profile details such as biography, follower/following/post counts, business classification, external website, public contact email/phone, and city. The connector aggregates commenters and likers into one deduplicated list and requires no login to run.

Call it via Sourcelane

curl -X POST https://cool-puffin-608.convex.site/v1/call \
  -H "Authorization: Bearer sl_live_your_agent_key" \
  -H "Content-Type: application/json" \

Request params

Field	Type	Required	Description
`posts`	array	optional	Instagram post or Reel URLs (or bare shortcodes), one per line, up to 50. Engagers are combined and de-duplicated across all of them.
`username`	string	optional	Optional. Instead of (or in addition to) listing posts, pull the most recent posts of this public profile and collect their engagers.
`postsPerProfile`	integer	optional	How many of the profile's most recent posts to scan when a username is given.
`includeCommenters`	boolean	optional	Collect everyone who commented on the posts (weighted 3x in the engagement score).
`includeLikers`	boolean	optional	Collect everyone who liked the posts (weighted 1x). Instagram only exposes a recent slice of likers for very popular posts.
`maxCommentsPerPost`	integer	optional	Stop reading a post's comments after this many. Higher values cost more on long threads.
`minPostsEngaged`	integer	optional	Only keep people who engaged with at least this many different posts - set to 2 or more to find repeat fans.
`excludePostAuthors`	boolean	optional	Drop the accounts that published the posts (they usually reply in their own comments).
`enrichProfiles`	boolean	optional	Look up each returned person's full profile - bio, follower and post counts, business category, website, public email and phone.
`maxItems`	integer	optional	Maximum people to return, most engaged first. 0 = no limit. Capped at 100 per call.
