Instagram Shared-Following / Common-Connections Mapper

Find the accounts that several Instagram profiles all follow. Feed in N public Instagram accounts and this actor computes the deterministic intersection of their follow graphs — the accounts they have in common — ranked by overlap_count. It is an audience-overlap and common-connections mapper for influencer marketing, competitive intelligence, community/niche research, and network analysis, built on real scraped follow edges (no estimation, no sampling).

What it does

• Common-connections intersection — one row per account followed by 2+ of your inputs, with overlap_count and the exact followed_by_inputs[] list.
• Ranked output — sorted by overlap_count (most-shared accounts first).
• Cross-input dedup — one row per unique account (pk), never charged twice.
• minOverlap filter — keep only accounts shared by at least K inputs.
• onlyVerified / excludePrivate filters — trim to verified or public accounts.
• Followers mode — switch scrapeMode to followers for shared-audience mapping.
• Graph edge-list export — bipartite source input handle → target followed handle edges for Gephi / networkx (in the Key-Value Store record edges and a per-run edges-<runId> dataset).
• Optional profile enrichment — on the deduplicated shared list only: biography, follower/following counts, external URL, business email/phone, category, plus regex-parsed bio emails/phones/links.
• Optional AI niche labelling — clusters enriched accounts into niche labels from their real bio text (off by default; multi-provider).
• scrapedAt timestamp on every row.

Input

Field	Type	Notes
urls	array	Instagram profile URLs or @handles (2+ for overlap)
scrapeMode	enum	following (default) or followers
maxItems	integer	Max follow-edges to fetch per input (0 = all)
minOverlap	integer	Minimum inputs that must follow an account (default 1)
onlyVerified	boolean	Keep only verified accounts
excludePrivate	boolean	Drop private accounts
includeProfileDetails	boolean	Enrich the deduped shared list
aiEnhancement	boolean	AI niche labelling (needs enrichment + API key)
aiModel / aiApiKey	string	Provider auto-detected from model name
sessionId	string (secret)	Instagram sessionid cookie — strongly recommended
proxyConfiguration	object	Apify Proxy (direct by default)

Example:

{
  "urls": ["https://www.instagram.com/nasa/", "nasaearth", "nasahubble"],
  "scrapeMode": "following",
  "maxItems": 300,
  "minOverlap": 2,
  "onlyVerified": false,
  "excludePrivate": false,
  "includeProfileDetails": true,
  "sessionId": "YOUR_SESSIONID_COOKIE"
}

Output

Each dataset row is one commonly-followed account:

• type, pk, username, full_name, is_verified, is_private
• overlap_count, followed_by_inputs[], profile_url, profile_pic_url
• Enrichment (when enabled): biography, follower_count, following_count, external_url, business_email, business_phone_number, category, bio_emails[], bio_phones[], bio_links[]
• ai_niche (when AI enabled), scrapedAt

The graph edge list is written to the Key-Value Store record edges and to a per-run edges-<runId> dataset.

Notes / compliance

• Scrapes only publicly available data. Private accounts' follow lists are not accessible. Values that are genuinely unavailable are emitted as null, never faked.
• Enrichment costs one extra request per unique shared account (the intersection only) — never per raw follow row, which keeps runs cheap.
• You are responsible for complying with applicable laws and platform terms.
