How this service works
Use for anything needing an up-to-date Brazilian benchmark rate: pricing a loan, indexing a contract, converting USD/BRL. No body required. Returns Selic (Copom policy rate), CDI (interbank rate) and USD/BRL (PTAX sell rate), each with its reference date, straight from the BCB's own SGS API.
Output
Returns a JSON object with three top-level keys: 'selic' (rate_pct and effective_date), 'cdi' (rate_pct and date), and 'usd_brl' (rate and date), plus a 'source' field confirming the data came from bcb-sgs. All rates are current as of their respective reference dates.
Example use cases
Loan pricing with current Selic
“I'm pricing a new Brazilian real-denominated loan and need the current Selic policy rate set by Copom — can you pull the latest figure from the Central Bank?”
Contract indexation to CDI
“I need to index a supplier contract to the current CDI interbank rate — what's the latest CDI value and its reference date from BCB?”
USD to BRL conversion for invoicing
“I'm about to send an invoice and need to convert USD amounts to BRL — what's the official PTAX sell rate from the Brazilian Central Bank today?”

Endpoint
POSThttps://tools.miniframe.com.br/taxas-bcb?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, up-to-date Brazilian financial benchmark rates (Selic, CDI, or PTAX USD/BRL) in a single call without managing BCB API credentials or rate-series codes yourself. Ideal for loan pricing, contract indexation, currency conversion, or any financial calculation anchored to official Brazilian Central Bank figures.
Side effects
- BCB SGS API unavailable or rate-limited — endpoint may return an error or stale data
- Network timeout if BCB upstream is slow
- Unexpected schema changes from BCB SGS could break parsing
- Rate data may lag by one business day around holidays or weekends
