How It Works

The scraper queries the CoinGecko API to retrieve cryptocurrency market data. For top-N queries, it fetches paginated market listings sorted by market cap. For specific coins, it retrieves detailed profiles including descriptions, links, and community data. Rate limiting with automatic retry on HTTP 429 ensures reliable operation within CoinGecko's free tier limits.
