Instagram Mentions Scraper → UGC & Creator-Discovery Lead Engine

Turn Instagram mentions into ranked, contactable creator leads. This Instagram mentions scraper finds the people who tag or mention a brand in their posts, deduplicates them into unique creators, and enriches each one with follower count, biography, contact details and a real engagement rate. It is built for UGC discovery, influencer marketing, brand monitoring, social listening and competitor mention tracking.

Unlike a plain Instagram scraper that dumps a brand's own feed, this actor reads the tagged-media feed — the posts where the target account is tagged — so every row is an external creator promoting the brand, not the brand itself.

What it does

1. Resolves each brand username to its Instagram user id.
2. Pages the tagged-media feed (usertags) — posts where the brand is tagged. The author of each post is the creator who tagged the brand = the lead.
3. Deduplicates authors into creator leads (tag count, first/last seen, total likes & comments).
4. Optionally enriches each unique creator with follower count, biography, external URL, business/public email, category and parsed bio contacts (emails, phones, Linktree-style links).
5. Computes a real engagement rate per creator ((likes + comments) ÷ follower count).
6. Adds videoUrl + videoDuration for Reels.
7. Optionally runs AI sentiment / topic / brand-safety tagging over real captions and preview comments.
8. Emits a competitive share-of-voice summary across multiple brands.

Output

Three row types share one dataset, distinguished by the type column:

• mention_post — one tagged post (creator, caption, likes, comments, media, videoUrl/videoDuration, engagement rate, optional AI fields).
• creator_lead — one aggregated unique creator (tag count, totals, follower count, bio, contacts, average engagement rate). Also mirrored to a per-run creator-leads-<runId> dataset.
• brand_summary — one per brand (tagged post count, unique creators, share-of-voice %).
• caption_mention — best-effort caption @-mentions (only when the hashtag supplement is on; clearly labeled non-exhaustive).

Coverage & honesty notes

• Tagged-media only. The core feed covers posts where the brand is tagged in media. Caption @-mentions have no exhaustive Instagram search endpoint — the optional hashtag scan is best-effort, not complete.
• Comment coverage is limited to the 2–3 preview_comments the feed exposes; this actor does not claim full comment-thread mention detection.
• No fabricated metrics. Reach, impressions, audience demographics and ad-value estimates are not available from public data and are never synthesized. Follower count is the only real reach proxy. Genuinely unavailable values are emitted as null, never faked.
• Engagement rate is derived only from real like/comment counts and the enriched follower count.

Compliance

Only publicly available data is collected. Respect Instagram's terms and applicable data-protection law (GDPR/CCPA) for any downstream use of scraped contact fields.
