TikTok Viral Breakout Velocity Watch

A stateful TikTok video tracker: spot which of your tracked videos are accelerating fastest since the last check, ranked by engagement velocity, with deltas as evidence.

Which of the TikTok videos I'm tracking are taking off fastest?

This Actor watches a fixed set of TikTok creators or video URLs. On each run it re-scrapes the videos, compares play, like, comment, and share counts against a saved baseline, and returns the breakouts ranked by velocity with evidence — so you find out what's accelerating, not just what the view count says today.

When an MCP agent should use this

• "Which of my tracked TikTok videos are taking off fastest since last week?"
• "Alert me when one of my brand's TikTok videos starts breaking out."
• "Rank my monitored TikTok videos by how fast their views are accelerating."
• "Spot a TikTok breakout before the view count makes it obvious."

How it works

1. Collect — re-scrapes the videos you monitor (with a trusted fallback source for reliability).
2. Snapshot & diff — compares against your saved baseline for this tracked set.
3. Classify / rank — turns the play/like/comment/share deltas into a velocityScore per video and flags breakouts above your threshold. This per-video trend analysis is the paid value: change over time, not a static count.
4. Emit — writes export-ready rows (JSON / CSV / XLSX) and updates the snapshot.

Inputs

Field	Required	Example
profilesOrUrls	yes	["https://www.tiktok.com/@brandhandle"]
maxVideos	no	100
breakoutThreshold	no	0.2 (only report videos up at least +20%)
mode	no	"check_for_changes" (default) or "reset_baseline"

Baseline run:

{ "profilesOrUrls": ["https://www.tiktok.com/@brandhandle"], "maxVideos": 100, "mode": "reset_baseline" }

Refresh run (the recurring job):

{ "profilesOrUrls": ["https://www.tiktok.com/@brandhandle"], "maxVideos": 100, "breakoutThreshold": 0.2, "mode": "check_for_changes" }

Example output

A ranked breakout row:

{
  "videoId": "7300000000000000000",
  "videoUrl": "https://www.tiktok.com/@brandhandle/video/7300000000000000000",
  "profileHandle": "brandhandle",
  "velocityScore": 0.42,
  "playCountDelta": 120000,
  "diggCountDelta": 8400,
  "commentCountDelta": 530,
  "shareCountDelta": 210,
  "evidence": ["Plays up +120,000 (+42%) since last check", "Shares up +210"],
  "sourceUrls": ["https://www.tiktok.com/@brandhandle/video/7300000000000000000"],
  "snapshotDate": "2026-06-05",
  "changeType": "velocity_breakout"
}

Modes

• check_for_changes (default) — compare against the baseline and return the videos accelerating fastest. Auto-creates the baseline on the first run, so use this almost every time.
• reset_baseline — save a fresh starting point and report nothing. Use only to re-baseline after you intentionally changed which videos you monitor.

Billing

Event	Price	When
video-checked	$0.015	One tracked video re-checked against the baseline and a velocity row emitted.

First 10 result rows of every run are free — keep maxVideos at 100+ so the allowance is a small share of the run.

FAQ

Is this a TikTok video tracker?

Yes — it's the stateful kind. Instead of one-shot TikTok video analytics that read today's view counts, it saves a baseline and tells you which of your tracked videos are accelerating since the last check, ranked by velocity.

Can I use it to find viral TikTok videos in general?

No. This watches a fixed set you already chose and reports change over time. For open "what's trending on TikTok today" discovery, use a raw hashtag or search scraper.

How early does it catch a breakout?

As early as your run cadence and breakoutThreshold allow. Lower the threshold to catch acceleration sooner; raise it to cut noise. It flags rising velocity before raw totals make a hit obvious.

Does it download the videos?

No. It tracks engagement metrics only. For video files, use a raw TikTok scraper.

Limits & support

• The first run on a new tracked set is a baseline; the velocity diff begins on the next run.
• Tracks engagement metrics (play / like / comment / share) only — no video downloads, no follower or comment-level signals.
• A failed fetch is reported clearly, never silently treated as "no changes".
