LinkedIn Jobs Scraper

I want to use the LinkedIn Jobs 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 a job title, location, and the number of rows you want returned.
4. Keep the returned job token and poll the marketplace job route for completion.

## Available Endpoints

### Remote Jobs ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-linkedin-jobs/remote-jobs" \
  -H "Content-Type: application/json" \
  -d '{
  "rows": 25,
  "title": "Product Designer",
  "location": "Remote"
}'

Use this when the primary filter is remote availability rather than a specific metro area.

### Search Jobs ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-linkedin-jobs/search-jobs" \
  -H "Content-Type: application/json" \
  -d '{
  "rows": 25,
  "title": "Staff Product Manager",
  "location": "San Francisco Bay Area"
}'

Use this for direct LinkedIn job discovery when the unit of search is a title and place rather than a company page or external job board.

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