  CoinGecko is a cryptocurrency data aggregator providing market data,
  analytics, and information on thousands of crypto assets, exchanges,
  derivatives, NFTs, and on-chain decentralized markets worldwide. The
  CoinGecko Developer Platform exposes three primary APIs: the public Crypto
  Market Data API (Demo plan and free tier), the commercial Pro API for higher
  rate limits and exclusive endpoints, and the Onchain DEX API powered by
  GeckoTerminal for decentralized exchange data across 250+ networks.
  Authentication uses x-cg-demo-api-key (Demo) or x-cg-pro-api-key (Pro)
  headers, with rate limits ranging from 30 calls per minute on Demo to 1,000
  calls per minute on top Pro tiers.
