How this service works
USD/BRL two ways: the official Central Bank PTAX rate and the LIVE crypto market — BTC/BRL, USDT/BRL and 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. Free sample, no payment: https://api.brazilayer.com/v1/mercado/amostra
Output
Returns the official PTAX USD/BRL rate from Brazil's Central Bank, live BTC/BRL and USDT/BRL prices sourced from Brazilian crypto exchanges, and a computed Brazil premium (ágio) expressed as a percentage showing how much above (or below) global prices Brazilians are paying for dollar or crypto exposure. A positive premium signals capital-flight pressure; a negative value signals inflows.
Example use cases
Capital flight pressure monitoring
“Check the Brazil crypto premium right now and tell me whether it's positive or negative — I want to know if there's capital-flight pressure or if money is flowing into Brazil.”
Crypto arbitrage desk FX snapshot
“Pull the live BTC/BRL and USDT/BRL prices from Brazilian exchanges alongside the official PTAX rate so I can see the spread and decide if there's an arbitrage opportunity.”
EM macro research FX comparison
“I'm writing a report on Brazilian monetary conditions — can you get me the official Central Bank PTAX rate and the current crypto market implied USD/BRL rate so I can show the divergence?”
Technical details
Endpoint
GEThttps://api.brazilayer.com/v1/mercado/cambioWhen to prefer
Choose this endpoint when you need a dual-lens view of Brazil's FX situation — both the official government PTAX rate and the live crypto market implied rate — plus the computed spread between them as a capital-flow signal. It is ideal for EM macro research, crypto arbitrage analysis, compliance checks requiring official BRL rates, or any agent workflow monitoring currency pressure in Brazil. Prefer it over generic FX APIs when the Brazil crypto premium (ágio) is specifically needed.
Side effects
