G2 Product Reviews Scraper

I want to use the G2 Product Reviews 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 the G2 product slug and the maximum number of reviews to fetch.
4. Keep the returned job token and poll the marketplace job route for completion.

## Available Endpoints

### Product Reviews ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-g2-reviews/product-reviews" \
  -H "Content-Type: application/json" \
  -d '{
  "product": "postman",
  "max_reviews": 200
}'

Use product slugs from G2 when you want review text and rating signals for customer feedback or competitor analysis.

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