Contact Info Scraper

I want to use the Contact Info 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 website URLs to crawl for contact details.
4. Keep the returned job token and poll the marketplace job route for completion.

## Available Endpoints

### Extract Contact Details ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-contact-info/extract-contact-details" \
  -H "Content-Type: application/json" \
  -d '{
  "maxPages": 25,
  "startUrls": [
    {
      "url": "https://example.com"
    }
  ],
  "mergeContacts": true,
  "enableLeadEnrichment": false,
  "enrichSocialProfiles": false
}'

Use this when the source of truth is a company website rather than a people database or social network profile.

### Extract Social Profiles ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-contact-info/extract-social-profiles" \
  -H "Content-Type: application/json" \
  -d '{
  "maxPages": 25,
  "startUrls": [
    {
      "url": "https://example.com"
    }
  ],
  "mergeContacts": true,
  "enrichSocialProfiles": true
}'

Use this when the primary goal is finding a company's social footprint from its website.

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