Technical details
Endpoint
GEThttps://api-macro-br-production.up.railway.app/v1/ptaxWhen to prefer
Choose this endpoint when you need the official, authoritative PTAX USD/BRL exchange rate published by the Banco Central do Brasil — especially for regulatory, accounting, tax, or compliance use cases where only the official central bank rate is acceptable. Prefer it over commercial FX APIs when the legal or official rate is required rather than a market mid-rate.
Side effects
- BCB data source temporarily unavailable — upstream API may return 503 or empty data
- Outside Brazilian business hours the PTAX rate may not have been published yet for the day
- Network timeout on Railway-hosted infrastructure
- Invalid or unsupported HTTP method returns 405
