TikTok Trending Hashtags API

Returns TikTok Creative Center's top trending hashtags for a country over 7, 30 or 90 days, overall or in one industry. Each has its rank, ID and tag page link, how many posts used it and how many views they drew in the window, its day-by-day popularity curve and its industry. With no parameters you get the US overall board for the latest 7 days.

One schema on 2 platforms.

The response reference lists every field, its type and when it is null. See the full schema.

Null means unknown
A field TikTok doesn't show is null, never zero or an empty string, so a real zero always means zero.
No input needed
Every parameter is optional: the plain request returns the default list.
Write one parser
TikTok and Instagram answer in these fields, so the code that reads one reads them all.

platformstring: Platform ID (tiktok, instagram, …).
idstring: Platform-native hashtag ID (TikTok's challenge ID, Threads' tag ID); on platforms whose public pages key a hashtag by its name (Instagram, YouTube, Facebook, X), the name lowercased.
namestring: The tag without #, as the platform shows it (case kept). Threads tags may contain spaces ("book club").
urlstring: Canonical hashtag page URL (for a multi-word Threads tag, its tag search page).
descriptionstring: The hashtag's description as its page shows it; null when it has none.
thumbnail_urlstring: The hashtag's own picture (not one of its posts' images); null when it has none. Platform CDN URLs can expire.
metricsobject: Counts at fetch time; null = hidden or not exposed, 0 = zero.
approximate_fieldsstring[]: JSON paths of values rounded by the platform or parsed from display text ("36M videos": metrics.post_count). [] when all exact.

What teams build with the TikTok Trending Hashtags API.

Pick rising hashtags before you post
Track which tags lead an industry weekly
Compare trending tags across countries

Good to know before you build.

Logged out, Creative Center shows only the top hashtags of each board and keeps the rest behind its login, so the page ends with page.end_reason platform_limit. Each industry is its own board: read several industries for more tags.
The window is Creative Center's latest published one, not the days up to now, so a board trails today by as long as Creative Center takes to update it. trend[].start_at shows which days it covers.
period_post_count and period_view_count count the board's window, not all time, so metrics.post_count and the all-time view_count are null here.
trend[] is Creative Center's popularity curve, one point a day, scaled 0 to 1 against the window's peak.
A country Creative Center publishes no board for returns invalid_input naming the countries it does.
