CoinGecko vs MercadoBitcoin
CoinGecko is one of the largest independent crypto data aggregators, tracking price, market cap, volume, and metadata for 17,000+ coins across 1,000+ exchanges without requiring registration for its free public endpoint. A Demo API key unlocks slightly higher limits, while paid Pro plans add exchange order-book data, NFT floor prices, and on-chain DEX data through the same JSON interface.
Mercado Bitcoin is Brazil's oldest and largest cryptocurrency exchange, operating since 2013 with spot trading across dozens of BRL pairs. Its v4 REST API and companion WebSocket service expose public market data — candles, order books, tickers — without authentication, while trading and account endpoints require an API key created from account settings. The API is free to use for individual developers.
