Spot viral TikToks before they peak.

Rank any TikTok feed by views/day velocity, read the hook that made each one blow up, and see whether a trend is still heating or already saturated — from a single scrape, no polling.

A view count tells you what already won. It can’t tell you the hook that made people stay, how fast a video is accelerating right now, or whether its format still has runway. viralcli returns all of it — per video, tracked over time, as a dataset you can build on.

01What you get

The signal, not just the view count.

One call, the whole record

Paste a TikTok URL and get back the stats, caption, hook transcript, storyboard, and views/day velocity — a single structured JSON object, not five scrapes to stitch.

v/day

Age-normalized velocity

Views divided by age, so a 2-day breakout and a 2-month evergreen are finally comparable. The number that means “going viral now.”

Hook + storyboard

The opening line as text and the visual beats as one image — read why a video worked instead of guessing from a thumbnail.

Discovery with a heating verdict

Give a keyword, get the breakout TikTok videos ranked by velocity plus an adoption histogram — and a one-word read on whether the format is heating, steady, or saturating. From a single scrape, no polling.

02The longitudinal layer

Not just a snapshot — the whole trajectory.

A single scrape tells you where a video stands. Keep watching it and you get the truth: how fast it’s accelerating, whether it’s peaking, and a history no one else has. viralcli tracks any video or keyword over time and pushes you events — over the same REST API and CLI your agents already call.

True velocity & acceleration

One scrape gives a lifetime average; tracking gives the truth. Two snapshots yield instantaneous views/day, three yield acceleration — so you know a video is peaking now, not just that it once went viral. Every tracked video returns its full trajectory.

Breakout & peaking webhooks

Track a video or keyword and the watcher polls it on an adaptive cadence — fast while it accelerates, slow once cold — and pushes a signed webhook the moment velocity crosses your threshold or the video peaks. No dashboard to babysit.

A dataset that compounds

Every snapshot lands in a longitudinal store — hot for live reads, Parquet for history — and is exportable. The view counts you capture today become time-series trend history no official API can backfill tomorrow.

03Coverage

TikTok coverage, one schema.

The same call shape works on every platform we cover — so an agent written for one is already written for all of them.

Analyze, discover, track.

One command, or one HTTP request, returns the whole record as JSON — then keeps watching it over time. Same shape on TikTok, Reels, and Shorts, so the code you write once runs everywhere.

How to find viral TikToks before everyone else

By the time a TikTok shows up on a 'trending' list, the window has closed. Catching a breakout early means watching speed, not totals — and reading what made it work fast enough to ride it. That's exactly what viral TikTok data from viralcli is built for.

Velocity finds breakouts; totals find history

A lifetime view count rewards old videos. Age-normalized views/day rewards the ones accelerating right now. viralcli ranks a TikTok feed by velocity so a 3-day-old rocket sorts above a 6-month-old hit — the difference between catching a trend and documenting one.

Read the hook that made it blow up

Every breakout in the list comes with its hook transcript — the opening words — and a storyboard of the visual beats. Instead of guessing why a viral TikTok worked, you read it, and you can reuse the structure on your own video the same day.

Is the trend still worth chasing?

A single discovery scrape reconstructs the format's adoption curve and flags it heating, steady, or saturating. Heating means runway; saturating means you're late. Add a breakout webhook and viralcli pings you the instant a TikTok's velocity crosses your threshold — no dashboards to watch.

Questions, answered.

It ranks videos by age-normalized velocity — views divided by the video's age in days — instead of lifetime views, so fast-accelerating clips surface while they're still climbing. A single discovery scrape also reconstructs the format's adoption curve to tell you whether the trend is heating or already saturated, and breakout webhooks fire the moment a video crosses your velocity threshold.
