Mastodon & Fediverse Influencer & Content Intelligence 🐘

Discover niche influencers, enrich accounts, scrape posts & engagement, and pull hashtag content from the Fediverse — no API key, no proxy.

Works on any Mastodon-compatible instance — so one actor covers Mastodon, Pleroma, Pixelfed and Firefish. Point it at an instance and:

• 🔥 Discover niche influencers — give it a hashtag (#art, #opensource, #photography) and get the accounts active in that niche, ranked by followers, each with an engagement score. (Federated — surfaces accounts from across many instances.)
• 👤 Account enrichment — handles → full profiles (followers, following, post count, bio).
• 📝 Posts & engagement — an account's posts with favourites/reblogs/replies.
• #️⃣ Hashtag content — every recent post under a hashtag.

Perfect for influencer marketing, community & brand monitoring, audience research, and social analytics on the open social web.

Uses the public Mastodon REST API — no key, no login, pure JSON. Very low maintenance.

Run it on a schedule

Track a hashtag's leaderboard or a set of accounts over time — pipe to a sheet, database or webhook.

Notes & limitations

• Uses public, unauthenticated endpoints — hashtag timelines, account lookup/statuses and account search. (The instance-wide public firehose is often login-gated; hashtag discovery covers the niche use case.)
• Coverage depends on the instance you query and how much of the Fediverse it federates with.
• Data source: the queried Mastodon-compatible instance.
