Why use the official Central Bank of Argentina rate?

When an auditor or tax office in Argentina asks which rate you used, "the ARS mid-market rate at 14:32" is not an answer — the official rate published by Central Bank of Argentina for that date is. This API returns exactly those published figures, stamped with the bank's own rate_date; on weekends and holidays the most recent published table is returned, as compliance rules expect.

Pairs the bank doesn't print directly are resolved from its table (inverse or cross via ARS) and explicitly flagged "derived": true — so what the bank printed and what was computed are never confused.

Endpoints

• GET /api/v1/central-bank/bcra/latest — latest table or single pair (all plans)
• GET /api/v1/central-bank/bcra/{YYYY-MM-DD} — the table for any date (paid plans)
• GET /api/v1/central-bank/bcra/history — time series, up to 5,000 rows (paid plans)
• GET /api/v1/central-bank/bcra/availability — publication calendar: the dates the bank actually published (all plans)

Full parameter reference in the API documentation. Every request counts toward your plan's monthly quota — rates change once per business day, so caching a published table locally makes a small quota go far.
