Hashtag videos

Videos posted with a hashtag, plus how big the hashtag is: total posts and views.

GEThttps://api.lurkapi.com/v1/tiktok/search/hashtag

When to use this

Use it to research a trend, a niche or a campaign hashtag: which creators post under it, what performs, and how big it is (hashtag.videoCount and hashtag.viewCount, exact). Videos come in the order tiktok.com's hashtag page shows them: neither newest nor most viewed first, and often months old.

Pagination. Up to 30 videos per page. Pass the response's cursor back as cursor (with the same hashtag) for more; has_more is false at the end. A few videos can repeat across pages, so dedupe by id. At times TikTok shows logged-out visitors only a handful of a hashtag's videos (with has_more: false), even for a big one. Full pages come back later.

Unknown hashtags return 404 not_found.

Example request

Copy one and replace YOUR_API_KEY with your API key (get one free). The code versions read the key from the LURKAPI_API_KEY environment variable instead.

curl "https://api.lurkapi.com/v1/tiktok/search/hashtag?hashtag=smallbusiness" \
  -H "x-api-key: YOUR_API_KEY"

Paste it into a terminal, with your key in place of YOUR_API_KEY.

const params = new URLSearchParams({
  hashtag: "smallbusiness",
});
const res = await fetch(`https://api.lurkapi.com/v1/tiktok/search/hashtag?${params}`, {
  headers: { "x-api-key": process.env.LURKAPI_API_KEY },
});
const data = await res.json();
if (!data.success) throw new Error(`${data.code}: ${data.error}`);
console.log(data.videos);

Node 18+. Save it as lurk.mjs and run node lurk.mjs. It reads your key from LURKAPI_API_KEY.

Pagination

Results come in pages. For the next page, repeat the call with the same parameters and add the response's cursor as cursor. On the last page, cursor is null. Each page costs 1 credit.

The first five pages, in JavaScript

let cursor = null;for (let page = 1; page <= 5; page++) {const params = new URLSearchParams({ hashtag: "smallbusiness" });if (cursor) params.set("cursor", cursor);const res = await fetch(`https://api.lurkapi.com/v1/tiktok/search/hashtag?${params}`, {headers: { "x-api-key": process.env.LURKAPI_API_KEY },});const data = await res.json();if (!data.success) throw new Error(`${data.code}: ${data.error}`);console.log(data.videos);cursor = data.cursor;if (!cursor) break; // last page}

Cost and freshness

Each call costs 1 credit. Calls turned away before they reach the platform (invalid parameters, a key or balance problem, a rate limit) are free, and so are 5xx errors. A not_found is charged, since the platform was checked. How charging works.

Answers are cached for up to 10 minutes. A repeat call within that time can return the same data, and costs the same.

Errors

A failed call returns success: false, an error message, a code your program can check, and a docs link. These are the errors this endpoint can return. All error codes.

Status	Code	Meaning
401	`missing_api_key`	No API key was sent. Put it in the `x-api-key` header.
401	`invalid_api_key`	This key doesn't exist or was revoked.
402	`insufficient_credits`	Not enough credits for this call. Buy a pack, or wait for tomorrow's free top-up.
402	`over_max_credits`	This call would cost more than the `max_credits` you set. The error says what it needs; raise `max_credits` to allow it. Not charged.
403	`account_suspended`	This account is suspended. Email support@lurkapi.com. Not charged.
404	`not_found`	What you asked for (a post, an ad, a subreddit) doesn't exist, or there's no endpoint at that path. Charged if the platform was checked.
405	`method_not_allowed`	Endpoints only take `GET`, with parameters in the URL.
429	`rate_limited`	Too many calls in a short time. Wait as many seconds as the `retry-after` header says, then retry.
500	`internal_error`	Something broke on our side. Retry. Not charged.
502	`upstream_error`	The platform didn't send a usable answer. Retry. Not charged.
503	`upstream_busy`	All our connections to the platform are busy. Retry in a few seconds. Not charged.
504	`upstream_timeout`	The platform took over 30 seconds to answer (90 for web pages). Retry. Not charged.

Use it in Claude

Connect LurkAPI to Claude and ask in plain English. This endpoint is the tiktok_hashtag_videos tool. For example:

Ask Claude

Use LurkAPI's tiktok_hashtag_videos tool with hashtag "smallbusiness", then summarize what you find.

Claude calls tiktok_hashtag_videos with arguments like these, and each call costs 1 credit:

Tool arguments

{"hashtag": "smallbusiness"}

To save tokens, tool results leave out empty fields, keep one URL per image or video, and give transcripts as plain text unless you pass timestamps=true. A result over 45,000 characters comes in parts. Its _note gives the offset for the next part, and later parts are free for 15 minutes. Pass trim=false for the full response.
