# Mercado Bitcoin API
> Live spot market data from Mercado Bitcoin, Brazil's largest and oldest crypto exchange — served straight from its public API, no key, nothing cached. Get a pair's last price, buy/sell, 24h high/low, open and 24h change (in Brazilian real); read live market depth with the best bid/ask and spread; and list 1,300+ trading pairs. A distinct Brazilian / Latin-American venue with real pricing, separate from other exchange feeds. Pairs are BASE-QUOTE (e.g. BTC-BRL).
