Mercado Cambio
by Brazilayer Markets in Markets & finance
x402 APIPassing, checked 2 h ago
USD/BRL two ways: the official Central Bank PTAX rate and the LIVE crypto market (BTC/BRL, USDT/BRL), plus the Brazil premium (ágio): how much Brazilians pay above global price for dollar/crypto exposure. A classic emerging-market capital-flow signal, computed live from exchange prices at request time. Positive premium = capital-flight pressure; discount = inflow.
