What people build with the LinkedIn Post Search API

Social listening

Every post this week that mentions your product, your competitor or a pain you solve.

Find warm leads

People posting about the exact problem you fix are the people to talk to first.

Content research

See which posts on a topic get the most engagement before you write your own.

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":"searchPosts","query":"AI agents","postedWithin":"7d","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":"searchPosts","query":"AI agents","postedWithin":"7d","limit":10}'

Inputs

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

Input	Type	What it does
query *	string	Words the posts must contain. Always needed, even with mentioning (a mention-only ask is refused, verified 2026-09-23): to list all that tags a company or person, use their name as the query. ≤300 chars
mentioning	text list	Only posts that tag these people or companies: /in/<slug> or /company/<slug> handles, or their URLs.
contentType	enum	What kind of post: videos, images, jobs, live_videos, documents, collaborative_articles. Omit or "all" for every kind.
postedWithin	enum
sort	enum
includeReposts	boolean	true: reposts of other people's posts count as hits too.
includeQuotePosts	boolean	true: posts that quote another post count as hits too.
limit	integer	1-50

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 13 rows

Field	Type
urn	string
body	string
kind	string
postedAt	string
permalink	string
mediaUrl	string
mediaType	string
likes	integer
comments	integer
reposts	integer
author	object
mentions	list of object
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 post	1	$0.002
10 posts	10	$0.02
A full page	50	$0.1

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 Post Search 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.

How is post search different from the posts API?

The posts API reads one person's recent posts. Post search finds posts across LinkedIn by keyword, from anyone.

How much does it cost?

$0.002 per post returned, up to fifty per call, with a free quote first.

Try it in a minute. $0.10 free.

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.
