# Central Bank of Argentina FX API
> Live official exchange-rate data for the Argentine peso (ARS) from the Central Bank of Argentina (Banco Central de la República Argentina, BCRA) — straight from its public Estadísticas Cambiarias API as clean JSON. Get the BCRA's official quote for every published currency against the peso for the latest business day, with both the peso-per-unit rate and the currency's USD parity; pull a single currency's peso rate, USD parity and the inverse; retrieve a currency's official daily peso rate over any date range from the BCRA's own series; read the BCRA's master list of quoted currencies; or convert an amount between any two quoted currencies (including ARS) cross-computed through the peso. Read live from the BCRA, nothing cached. This is the official Argentine-peso central-bank rate — distinct from the ECB, BCB, SNB, Bank of Canada and other central-bank feeds and from market mid-rates: the BCRA's own published peso quotes.
