Search TikTok Ad Library

When to use this

Use it to see what a brand or a category advertises on TikTok: each ad with its advertiser, caption, video or images, when it ran and roughly how many people saw it. This is TikTok's Ad Library under the EU Digital Services Act, so it only has ads shown in the EU/EEA, Switzerland, the UK and Turkey. Ads shown only in the US or elsewhere aren't in it.

Search by query, a keyword matched against ad text and advertiser names (so resellers show up too), or by advertiser_name for one advertiser's ads, spelled as the library shows it (e.g. NIKE Retail B.V., as in a result's advertiser_name). Results are ads shown in the last 30 days, most relevant first. region narrows them to one country; an ad that ran in several countries appears under each.

Pagination. 12 ads per page. Pass the response's cursor back as cursor (with the same params) for more; has_more is false at the end. For keyword searches total stops counting at 5,000.

An advertiser_name the library doesn't know returns 404 not_found, with close matches in the message.

Parameters

All parameters go in the query string.

Example request

Replace YOUR_API_KEY with your key, or set LURKAPI_KEY for the code. Get a free key.

curl "https://api.lurkapi.com/v1/tiktok/ad-library/search?query=running+shoes&region=DE" \
  -H "x-api-key: YOUR_API_KEY"

const params = new URLSearchParams({
  query: "running shoes",
  region: "DE",
});
const res = await fetch(`https://api.lurkapi.com/v1/tiktok/ad-library/search?${params}`, {
  headers: { "x-api-key": process.env.LURKAPI_KEY },
});
const data = await res.json();
if (!data.success) throw new Error(`${data.code}: ${data.error}`);
console.log(data.ads);

import os
import requests

res = requests.get(
    "https://api.lurkapi.com/v1/tiktok/ad-library/search",
    params={
        "query": "running shoes",
        "region": "DE",
    },
    headers={"x-api-key": os.environ["LURKAPI_KEY"]},
    timeout=60,
)
data = res.json()
if not data["success"]:
    raise RuntimeError(f"{data['code']}: {data['error']}")
print(data["ads"])

Example response

A real response from this endpoint, captured from the live API and trimmed to a couple of items. Strings over 96 characters (mostly signed media URLs) are cut short and end in ….

Response fields

Every field of a successful response. [] marks a list: a[].b is the b of each item in a. nullable fields can be null; optional fields can be missing.

Pagination

Pass the response's cursor back as cursor, with the other parameters unchanged, for the next page. It's null on the last page. Each page costs 1 credit.

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

Caching and freshness

Responses are cached for up to 1 hour, so a repeat call within that window can return the same data. It still costs 1 credit.

Errors

Errors return { success: false, error, code, docs } with the HTTP status below. Validation errors, 401/402/429 rejections and 5xx failures are free; not_found is charged (how charging works). All error codes.

Use it in Claude

Once LurkAPI is connected to Claude, this endpoint is the tiktok_ad_library_search tool. Ask in plain English, for example:

Use LurkAPI's tiktok_ad_library_search with query "running shoes", region "DE" and summarize what you find.

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

{
  "query": "running shoes",
  "region": "DE"
}

Tool results skip nulls and empty lists to save tokens.
