Amazon Product Scraper

I want to use the Amazon Product 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 Amazon product or category URLs and optional country or result limits.
4. Keep the returned job token and poll the marketplace job route for completion.

## Available Endpoints

### Category Products ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-amazon/category-products" \
  -H "Content-Type: application/json" \
  -d '{
  "country": "US",
  "maxItems": 25,
  "startUrls": [
    {
      "url": "https://www.amazon.com/s?k=mechanical+keyboard"
    }
  ]
}'

Use this when the input is an Amazon category or search results page rather than a direct product URL.

### Product Details ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-amazon/product-details" \
  -H "Content-Type: application/json" \
  -d '{
  "country": "US",
  "maxItems": 10,
  "startUrls": [
    {
      "url": "https://www.amazon.com/dp/B09X7MPX8L"
    }
  ]
}'

Use this when you already know the product URLs and want the clearest product-detail workflow.

### Scrape Products ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-amazon/scrape-products" \
  -H "Content-Type: application/json" \
  -d '{
  "country": "US",
  "maxItems": 10,
  "startUrls": [
    {
      "url": "https://www.amazon.com/dp/B09X7MPX8L"
    }
  ]
}'

Use this for Amazon-specific product and category scraping when you need ASIN-aware output and Amazon pricing data. ASIN-aware means the results include Amazon Standard Identification Numbers, the unique product IDs Amazon uses for listings.

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