- **Competitive ad research.** Every ad a competitor is running on LinkedIn right now, with the copy and the landing page.
- **Messaging research.** See how a market talks to its buyers before you write your own campaigns.

## Quote it, then run it

1. free quote: the exact price, nothing charged:

```bash
curl -X POST https://apiforagents.dev/v1/linkedin \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"adsLibrary","subject":"https://www.linkedin.com/ad-library/search?companyIds=<company-id>","limit":10,"estimateOnly":true}'
```

2. the same call, run:

```bash
curl -X POST https://apiforagents.dev/v1/linkedin \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"adsLibrary","subject":"https://www.linkedin.com/ad-library/search?companyIds=<company-id>","limit":10}'
```

## Inputs

Everything you can send in one adsLibrary call. Required inputs first.

| Input | Type | What it does |
|---|---|---|
| subject * | string | An Ad Library URL. An advertiser page or one ad's detail page. ≤400 chars |
| limit | integer | 1-100 |

## What comes back

The fields of every row, always present. Nothing is guessed: a value that could not be measured is null, and the answer's coverage says why.

| Field | Type |
|---|---|
| adId | string |
| adUrl | string |
| advertiserUrl | string |
| paidBy | string |
| headline | string |
| body | string |
| format | string |
| mediaType | string |
| mediaUrl | string |
| clickUrl | string |
| impressions | integer |
| targetingLocation | string |
| started | string |
| ended | string |
| daysActive | integer |
| details | object |

details is always the last field: everything else the source sent for that row, under our own field names. Its keys depend on the source that answered, so read them defensively; it is {} when there is nothing more.

## A sample answer

Made-up names and values in the real field names, so you can see the shape before you spend anything.

| paidBy | headline | body | format | mediaType | impressions |
|---|---|---|---|---|---|
| Northfold | Close your books 3x faster | Finance teams at 400+ companies close in 2 days. | SINGLE_IMAGE | image | 10k-50k |
| Northfold | The 2026 finance team benchmark | Download the report: 1,200 teams surveyed. | DOCUMENT | document | 50k-100k |
| Northfold | See it in 90 seconds | A quick tour of month-end close, start to finish. | VIDEO | video | 1k-5k |

## Pricing

Pay as you go, in US dollars, per record. No subscription, nothing expires, $5 first top-up, and every new agent starts with $0.10 free.

| Request | Records | At the list price |
|---|---|---|
| One ad | 1 | $0.002 |
| 10 ads | 10 | $0.02 |
| A full page | 100 | $0.2 |

These are per-record list prices. Some calls also carry a minimum, such as a page of search results, so a small request can cost more than the table shows. The quote ("estimateOnly": true) is free, gives the most your exact request can cost, and the charge then settles to what came back. Records that do not come back are refunded.

## Try it without writing code

- [Open the LinkedIn Ad Library API in the playground](https://apiforagents.dev/dashboard/run?platform=linkedin&op=adsLibrary): The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type.

## Why this one, and not a scraper you run yourself

- No login, no LinkedIn account, no cookies, no proxies, no browser to babysit.
- When the site changes its pages, your request stays the same: keeping the reads working is our job, not yours.
- A fetch that fails costs nothing: it is named in the answer with a reason, and the quote says the most a call can cost before it runs.

## Questions

### What does the LinkedIn Ad Library API return?

One row per ad: ad id and URL, advertiser URL, who paid, headline, body, format, media type and URL, click URL, impressions where LinkedIn shows them, targeting location, and start and end dates.

### What do I pass in?

A LinkedIn Ad Library URL: an advertiser's page (all their live ads) or a single ad's detail page.

### How much does it cost?

$0.002 per ad returned, up to a hundred per call.

## Why API for Agents

- One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
- A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
- Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
- $0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
- Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
- Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
- Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
- Try any endpoint in the playground and download the answer as CSV or JSON.
