Reddit Community Scraper

I want to use the Reddit Community 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 subreddit names or search queries and optional sort filters.
4. Keep the returned job token and poll the marketplace job route for completion.

## Available Endpoints

### Community Posts ($0.0001 USDC)
curl -X POST "https://api.marketplace.fast.xyz/api/apify-reddit/community-posts" \
  -H "Content-Type: application/json" \
  -d '{
  "sort": "top",
  "time": "month",
  "maxItems": 25,
  "subreddits": [
    "LocalLLaMA"
  ],
  "maxComments": 20
}'

Use this for subreddit monitoring, consumer discussion analysis, and community-driven trend research.

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