LinkedIn Company Employees Scraper

I want to use the LinkedIn Company Employees Scraper service on Fast Marketplace.

## Setup (skip if you already have Fast Marketplace set up)
1. Open the marketplace skill: https://marketplace.fast.xyz/skill.md
2. Fund a Fast wallet on mainnet.
3. Provide one or more LinkedIn company URLs and optional location or title filters.
4. Keep the returned job token and poll the marketplace job route for completion.

## Available Endpoints

### Company Employees ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-linkedin-employees/company-employees" \
  -H "Content-Type: application/json" \
  -d '{
  "maxItems": 100,
  "companies": [
    "https://www.linkedin.com/company/google"
  ],
  "jobTitles": [
    "Software Engineer"
  ],
  "locations": [
    "New York"
  ],
  "profileScraperMode": "Short ($4 per 1k)"
}'

Use this when the starting point is a target account and you need employee discovery rather than direct profile enrichment.

For paid endpoints: the first call returns 402. Authorize payment with your Fast wallet and retry with the payment signature header.
