LinkedIn ad details

When to use this

Use the adLibraryUrl from ad search. Returns the public ad preview and any payer, run-date, impression and targeting disclosures LinkedIn publishes. These may be absent outside EU-delivered ads. Counts and dates stay in LinkedIn's display format rather than guessing exact values. A restricted creative is marked restricted, while genuine delivery disclosures remain available.

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/linkedin/ad?url=https%3A%2F%2Fwww.linkedin.com%2Fad-library%2Fdetail%2F1558746953" \
  -H "x-api-key: YOUR_API_KEY"

const params = new URLSearchParams({
  url: "https://www.linkedin.com/ad-library/detail/1558746953",
});
const res = await fetch(`https://api.lurkapi.com/v1/linkedin/ad?${params}`, {
  headers: { "x-api-key": process.env.LURKAPI_KEY },
});
const data = await res.json();
if (!data.success) throw new Error(`${data.code}: ${data.error}`);
console.log(data.images);

import os
import requests

res = requests.get(
    "https://api.lurkapi.com/v1/linkedin/ad",
    params={
        "url": "https://www.linkedin.com/ad-library/detail/1558746953",
    },
    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["images"])

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.

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 linkedin_ad tool. Ask in plain English, for example:

Use LurkAPI's linkedin_ad with url "https://www.linkedin.com/ad-library/detail/1558746953" and summarize what you find.

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

{
  "url": "https://www.linkedin.com/ad-library/detail/1558746953"
}

Tool results skip nulls and empty lists to save tokens.
