TikTok Hashtag Search API

Returns the TikTok hashtags a web search finds for your words, each with its name and link, a page at a time. Its post count and TikTok's description of it come too when the search index shows them. Add fill=true to also get each hashtag's full live record (its ID, exact post and view counts, picture) in the same response.

200 OK · GET https://socialtap.dev/v1/tiktok/search_hashtagsLong arrays and strings are shortened here. Real responses are complete.Docs

One schema on 6 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.
What it accepts
Words to find TikTok hashtags by, as a web search reads them: a topic, a niche, a community (cooking, home gym, "meal prep").
Write one parser
TikTok, Instagram, Facebook and 3 more platforms answer in these fields, so the code that reads one reads them all.

platformstring: Platform the item is on.
typestring: The kind of item the result names, as the resource that describes it: profile (an account), post, hashtag, sound, place or community. The item's summary is the field of that name, and a filled result's record is details.<type>. A search that finds several kinds (a platform's top search) mixes them in one list. New values may be added as more kinds are searchable; treat unknown values as other.
positioninteger: Zero-based rank of the result in the list, across pages: the search engine's order, counting only the results kept.
urlstring: The item's canonical link on the platform (the account's page for a profile, the post's for a post).
matched_urlstring: The page the index listed: the item's own page, or one of its pages that names it (a video of an account, for a profile found through it).
titlestring: The page's title as the index shows it: often the item's name, but not the item's own field. Null when the index shows none.
snippetstring: The index's excerpt of the page: often the item's description and counts as the page stated them when it was indexed, days or weeks ago. Null when the index shows none.
profileobject: The account the result names (type profile): what its link and the index's text say of it, completed from details when the result is filled. Null for every other type.

What teams build with the TikTok Hashtag Search API.

Find the hashtags around a niche
Pick campaign tags by their size
Turn a keyword into hashtags to track

Good to know before you build.

TikTok has no logged-out hashtag search, so results come from a web search engine's index of TikTok's tag pages, in that engine's ranking.
A tag is listed when its page is indexed and matches your words: its name can contain them (cookk for cooking) as well as equal them.
Without fill, a result's id and thumbnail are null, and its post count and description are the index's copy of the tag page: rounded, possibly weeks old (listed in approximate_fields), and null when the snippet quotes one of the tag's videos instead.
With fill=true each result's details.hashtag is the tag's live record from the TikTok Hashtag API, and its summary is updated from it.
A result the hashtag lookup couldn't fetch stays unfilled and costs nothing extra, and meta.warnings says how many.
For the videos themselves, in TikTok's own ranking for a keyword, use the TikTok Search API.
The index goes only so deep: a search usually ends after two or three pages (page.end_reason end).
Case doesn't matter, and site: operators in your query are removed.
