- Free to start: $0.10

## The ideas

- **[A B2B lead list builder](https://apiforagents.dev/platforms/linkedin/people-search-api).** For sales teams with a clear customer profile. It searches people by title, seniority, industry and company size, then saves each match to a sheet or CRM. Uses searchPeople.
- **[An account brief before a sales call](https://apiforagents.dev/platforms/linkedin/company-api).** For account executives who want context fast. It reads the company page, what the company is hiring for and recent posts that mention it, and writes a one-page brief. Uses companies, jobs and searchPosts.
- **[A job-change alert for champions](https://apiforagents.dev/platforms/linkedin/profile-api).** For customer success and sales teams. It re-reads the profiles of past buyers each month and flags anyone whose current position has changed. Uses profiles.
- **[A hiring-signal feed](https://apiforagents.dev/platforms/linkedin/jobs-api).** For vendors whose product fits a team that is growing. It searches new job listings for a role in chosen locations and lists the companies posting them. Uses jobs.
- **[A company list by market](https://apiforagents.dev/platforms/linkedin/company-search-api).** For founders and analysts sizing a market. It searches companies by keyword, location, industry and headcount band and exports the list. Uses searchCompanies.
- **[A buying committee map](https://apiforagents.dev/platforms/linkedin/people-search-api).** For sellers working one target account. It searches that company's people by function and seniority to show who leads each team. Uses searchPeople.
- **[A post engagement lead finder](https://apiforagents.dev/platforms/linkedin/reactions-api).** For marketers who post on a topic. It lists the people who reacted to or commented on a post, with their headlines, for a human to review. Uses postReactions and postComments.
- **[A topic listening feed](https://apiforagents.dev/platforms/linkedin/post-search-api).** For product and research teams. It searches posts by keyword from the last week, newest first, and sends a short digest. Uses searchPosts.
- **[A founder content benchmark](https://apiforagents.dev/platforms/linkedin/posts-api).** For founders and ghostwriters. It reads the recent posts of peers with likes, comments and reposts to see which formats get replies. Uses posts.
- **[A competitor ad tracker](https://apiforagents.dev/platforms/linkedin/ads-library-api).** For growth teams. It reads a rival's ads from the Ad Library with headline, format, impressions and days active, and flags new ones. Uses adsLibrary.
- **[A candidate sourcing assistant](https://apiforagents.dev/platforms/linkedin/people-search-api).** For recruiters. It searches people by title, location and years of experience, then reads full profiles with skills and positions for a shortlist. Uses searchPeople and profiles.
- **[A CRM enrichment job](https://apiforagents.dev/platforms/linkedin/profile-api).** For revenue operations teams with stale records. It refreshes headline, location and current position for each contact by LinkedIn handle. Uses profiles.
- **[A prospect interest digest](https://apiforagents.dev/platforms/linkedin/profile-comments-api).** For sellers who want a real reason to reach out. It reads what a prospect has commented on and reacted to lately and lists the topics. Uses profileComments and profileReactions.

## How to start

1. Sign up. An agent registers itself with one POST and starts with $0.10 of free credit; a person can sign up on the site instead.
2. Quote the first call for free: send the searchPeople request with "estimateOnly": true and read the price before anything is spent.
3. Run the same call with "maxUsd" set as a ceiling, and keep the rows it returns.
4. Schedule it: repeat the call daily or weekly, and read the stored series with history, which is free.

## Questions

### Where should the handles come from?

From evidence: a people search, a company search, or a pasted URL. A handle typed from a guess can belong to someone else and is still charged.

### Do I need a LinkedIn account to build these?

No. The API reads public data and never asks for your login, password or cookie.

### What does a run cost?

LinkedIn records are priced from $0.001 per record. A call can carry a minimum, so send it first with "estimateOnly": true. The quote is free and is the most the call can cost.

### Can an AI agent build and run these on its own?

Yes. It signs itself up with one call and gets $0.10 free, quotes each call before it spends, and pays from a prepaid balance. "maxUsd" caps every call, and only a person can add money.

## 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).
