LinkedIn ad details

When to use this

Use it to read one ad in full: its creative, who paid for it, when it ran, and its impressions and targeting where LinkedIn publishes them. Pass the adLibraryUrl from ad search (linkedin_search_ads).

LinkedIn mostly publishes these details for ads shown in the EU, so elsewhere they're often missing. Counts and dates come as LinkedIn writes them; we don't guess exact values. When LinkedIn hides the ad's preview, restricted is true, but its delivery details can still be there.

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/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?${params}`, {
  headers: { "x-api-key": process.env.LURKAPI_API_KEY },
});
const data = await res.json();
if (!data.success) throw new Error(`${data.code}: ${data.error}`);
console.log(data.images);

Response fields

Every field in a successful response, and what it means. A name with [] belongs to each item of a list: videos[].url is the url of every item in videos. null means there's no value.

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 1 hour. 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.

Use it in Claude

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

Use LurkAPI's linkedin_ad tool with url "https://www.linkedin.com/ad-library/detail/1558746953", then 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"}

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.
