What people build with the LinkedIn Profile Reactions API

Read intent

What someone likes this week says what they are thinking about. Use it to time and tailor outreach.

Map influence

Find the voices a group of buyers keeps reacting to.

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":"profileReactions","subjects":["satyanadella"],"limit":25,"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":"profileReactions","subjects":["satyanadella"],"limit":25}'

Inputs

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

Input	Type	What it does
subjects *	text list	/in/<slug> handles or profile URLs. 1-10 items
postedWithin	enum
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 24 rows

Field	Type
reactorProfileId	string
reactorHandle	string
reactorName	string

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 reaction	1	$0.002
10 reactions	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 Profile Reactions 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 it return?

Reaction rows: the reaction type, the post URL, author and text, and when, for reactions the person left anywhere on LinkedIn.

How much does it cost?

$0.002 per reaction returned.

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.
