## 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.

| Name | Type | Required | Default | Allowed values | Description | Example |
| --- | --- | --- | --- | --- | --- | --- |
| `url` | string | yes |  |  | Public LinkedIn Ad Library detail URL from the adLibraryUrl field of search ads. | `https://www.linkedin.com/ad-library/detail/1558746953` |

## Example request

Replace `YOUR_API_KEY` with your key, or set `LURKAPI_KEY` for the code. [Get a free key](https://lurkapi.com/login?next=/dashboard).

## 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](https://lurkapi.com/docs.md#credits)). [All error codes](https://lurkapi.com/docs.md#errors).

| 401 | `invalid_api_key` | The key is unknown or was revoked. |

| 404 | `not_found` | The endpoint, or the thing you asked for (ad, post, subreddit), doesn't exist. Charged when the platform was checked. |
| 405 | `method_not_allowed` | Endpoints take GET with query params. |

## Use it in Claude

Once LurkAPI is [connected to Claude](https://lurkapi.com/docs.md#claude), this endpoint is the `linkedin_ad` tool. Ask in plain English, for example:

Ask Claude:

```text
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:

Tool arguments:

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

Tool results skip nulls and empty lists to save tokens.
