Niche YouTube Creator Leaderboard

SKILL: Niche YouTube Creator Leaderboard
Subscriber/follower counts are lagging vanity metrics. Pairing the niche creator roster with this month's and this week's real engagement exposes the over-indexers truly winning right now. YouTube is the always-on core; TikTok and Instagram can be toggled on to find momentum creators wherever they post, applying the same velocity-over-vanity logic.

You are running this skill on API Direct via its MCP tools. Execute the steps below yourself by calling the named tools in order — values in <angle brackets> come from a previous step. Then deliver the result described at the end.

INPUTS:
  - niche (required): <niche — ASK THE USER>
      The niche to rank momentum creators within
  - platforms (optional): (optional — e.g. tiktok, instagram)
      Comma-separated list of platforms to run — options: youtube, tiktok, instagram. Omit to run all of them; name specific platforms to limit the run.
  - depth (optional): 3 (default — override if you like)
      Optional. How many pages to pull per platform — more pages means a deeper roster and more videos/posts for accurate velocity attribution. Defaults to 3.
  - region (optional): (optional — e.g. US)
      Optional. Region code to scope the TikTok momentum search to a specific market when scouting region-specific creators. Only affects the TikTok step.

PLATFORM SELECTION: some steps are gated with "Only run if {platforms} includes X". If the user supplied a `platforms` value, run only the steps whose platform is listed. If the user did NOT supply `platforms`, run ALL steps — every platform the skill supports.

STEPS:
  1. Tool `search_youtube_channels` — search_youtube_channels(query={niche}, pages=3)
     Core (always runs): build the candidate roster of niche YouTube channels and record each subscriber_count as the vanity baseline.
  2. Tool `search_youtube` — search_youtube(query={niche}, upload_date=this_month, get_sentiment=true, pages=3)
     Core: pull this month's uploads, attribute view counts back to channels, and flag which are drawing positive reception via sentiment.
  3. Tool `search_youtube` — search_youtube(query={niche}, upload_date=this_week, pages=3)
     Core: layer in this week's breakout videos and rank channels by view-velocity relative to subscriber base to surface the momentum over-indexers.
  4. Tool `search_tiktok` — search_tiktok(query={niche}, publish_time=7, sort_by=most_liked, get_sentiment=true, pages=3)
     Only run if {platforms} includes tiktok: pull the week's most-liked niche TikToks (optionally scoped to {region}), attribute like-velocity to creators, and rank the TikTok momentum risers by engagement velocity, not follower vanity.
  5. Tool `search_instagram` — search_instagram(query={niche}, get_sentiment=true, pages=3)
     Only run if {platforms} includes instagram: pull recent niche Instagram posts, attribute engagement back to creators, and surface the accounts over-indexing on recent engagement velocity for the same momentum leaderboard.

DELIVER: A live, optionally cross-platform leaderboard of the niche's top creators ranked by momentum (view/engagement velocity versus follower base) rather than subscriber count alone — YouTube by default, with optional TikTok and Instagram extensions under the user's control.

Note: each underlying tool call is billed at its normal endpoint price; get_sentiment adds a small per-page surcharge. Page through results as needed but stop once you have enough to deliver the outcome.
