Inputs

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

Input	Type	What it does
query	string	≤300 chars
locations	text list
companySizes	enum list	Headcount bands: 1-10, 11-50, 51-200, 201-500, 501-1000, 1001-5000, 5001-10000, 10001+; any match.
industries	text list	Industry names, leaf or " > " path, from LinkedIn's own taxonomy.
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 27 rows

Field	Type
universalName	string
urn	string
name	string
industry	string
sizeBucket	string
employeesCount	integer
followers	integer
website	string
linkedinUrl	string

jobsUrl	string
callToActionUrl	string
locations	list of object
employeesByLocation	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.

ledgerly	Ledgerly	Software Development	11-50	38	4120
coinmint	Coinmint	Financial Services	51-200	96	12800

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 company	1	$0.004
10 companies	10	$0.04
A full page	50	$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 Company 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.

What can I filter companies by?

Keyword, locations, company sizes and industries, with a limit of up to fifty results per call.

Priced per company returned, with a free quote first. See the pricing page for the current rate.

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.
