Google ads by company

When to use this

Use it to study a competitor's Google and YouTube ads: formats, run dates and how long each ad has run. Pass domain (e.g. nike.com, every advertiser promoting it) or advertiser_id from search advertisers (google_search_advertisers).

Filter by region, platform, format and date range. topic=political lists election ads with their spend and impressions, and needs a region. For an ad's text, landing page and per-country stats, pass its ids to ad details (google_ad).

Pagination. Up to 100 ads per page. Pass cursor back with the same filters for the next page; it's null on the last page. Date ranges that start more than about a year back come back empty.

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/google/company/ads?domain=nike.com&region=US" \
  -H "x-api-key: YOUR_API_KEY"

const params = new URLSearchParams({
  domain: "nike.com",
  region: "US",
});
const res = await fetch(`https://api.lurkapi.com/v1/google/company/ads?${params}`, {
  headers: { "x-api-key": process.env.LURKAPI_KEY },
});
const data = await res.json();
if (!data.success) throw new Error(`${data.code}: ${data.error}`);
console.log(data.ads);

import os
import requests

res = requests.get(
    "https://api.lurkapi.com/v1/google/company/ads",
    params={
        "domain": "nike.com",
        "region": "US",
    },
    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({ domain: "nike.com", region: "US" });
  if (cursor) params.set("cursor", cursor);
  const res = await fetch(`https://api.lurkapi.com/v1/google/company/ads?${params}`, {
    headers: { "x-api-key": process.env.LURKAPI_KEY },
  });
  const data = await res.json();
  if (!data.success) throw new Error(`${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 12 hours, 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 google_company_ads tool. Ask in plain English, for example:

Use LurkAPI's google_company_ads with domain "nike.com", region "US" and summarize what you find.

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

{
  "domain": "nike.com",
  "region": "US"
}

Tool results skip nulls and empty lists to save tokens.
