What people build with the LinkedIn Ad Library API

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

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

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.

Show all 16 rows

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.

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 playgroundThe 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 people ask.

What does the LinkedIn Ad Library API return?

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 people pick 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.
