# Market mapping with LinkedIn data. Every company in a niche.

> Map a market from LinkedIn: every company in a niche by industry, size and location, with employee counts and websites. $0.004 per company.

Canonical: https://apiforagents.dev/use-cases/market-mapping · Updated 2026-10-16

Size a market before you build or sell into it: search companies by keyword, industry, size and location, then compare headcount, followers and founding years across the whole set.

- For: Founders, investors, analysts
- Billed: Per record
- Free to start: $0.10
- Minimum top-up: $5

## How it works

1. Search companies by keyword and filters, a page of fifty at a time.
2. Compare employee counts, founding years and specialities across the set.
3. Repeat monthly: every value is dated, so growth is visible.

## The calls

a niche:

```json
{
  "op": "searchCompanies",
  "query": "climate tech",
  "locations": [
    "Germany"
  ],
  "limit": 50
}
```

## What it costs

At today's per-record prices, pay as you go. Quotes are free, records that do not come back are refunded, and a record your account already fetched today is free.

| Job | Records | Cost |
|---|---|---|
| A 50-company niche | 50 companies | $0.20 |
| A 500-company market | 500 companies | $2.00 |

## 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.

## Start

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. Open it at https://apiforagents.dev/dashboard/run (sign in first).
